Although officially called lady beetles, members of the family Coccinellidae are more commonly known as ladybugs (American) or ladybirds (Great Britain, Australia, Canada). This is the largest of the cucujoid families with nearly 6,000 described species and about 370 genera worldwide. They are among the most familiar and beloved of insects, and are widely recognized for their role in controlling voracious plant pests such as aphids and scale insects. Not surprisingly, in many cultures coccinellid beetles are considered harbingers of good luck and a bountiful harvest. Even the common name, which dates back to medieval times, is a testament of their sacred status as "beetles of Our Lady" (in reference to the virgin Mary).
Lady Beetles are small, round, with convex wing-covers. The head and pronotum are often shiny black with white markings, while the wing-covers are often shiny orange-red with black dots. Some species, however, are predominantly black, or gray with black dots, and may have fine hairs on their bodies. The adults usually feed on aphids, scale insects, and other small insects, while the larvae tend to feed on the same kinds of insects. Adults occasionally appear on flowers with exposed nectaries to feed on nectar. Lady Beetles are considered beneficial insects, although a few species feed on the foliage of crop plants.

M. E. Mulsant
Present day members of the family Coccinellidae first appeared in Linnaeus’ (1758) Systema Naturae under the genus Coccinella, which contained, at the time, 36 species. Redtenbacher (1844) provided the first internal classification system for the family by recognizing two biologically defined groups, the plant feeders and the aphid feeders. His phytophagous group corresponds to the subfamily Epilachninae (sensu Sasaji 1968) but the aphidophagous one spans the other currently recognized subfamilies. Mulsant’s (1846; 1850) interpretation of the family diversity divided Coccinellidae into the “Trichoisomides” (the hairy species) and the “Gymnosomides” (the glabrous ones), a system that was even more artificial than its predecessor. Mulsant, however, was the first author to recognize supra-generic categories for the family many of which correspond to the current tribes in Coccinellidae. Korschefsky’s (1931) classification recognized the subfamilies Epilachninae, Coccinellinae, and Lithophilinae. This system is consistent with that of Redtenbacher but further subdivides the entomophagous taxa (the so-called “aphidophaga”) on the basis of the tarsal structure. Despite these advances, the classification of Coccinellidae was still rudimentary and extremely artificial until the second half of the 20th century.
In the most influential series of works of the 20th century dealing with this topic, Sasaji (1968; 1971a, b) revised the classification of the family, proposing six subfamilies: Sticholotidinae, Coccidulinae, Scymninae, Chilocorinae, Coccinellinae and Epilachninae. This system was widely accepted and remains the primary reference for the family (e.g., Booth et al., 1990; Pakaluk et al., 1994; Lawrence and Newton, 1995; Kuznetsov, 1997). Additional subfamilies have since been recognized: Azyiinae and Exoplectrinae, elevated from tribal status (Gordon, 1994); Ortaliinae, for Ortaliini plus Noviini (Kovář, 1996); and Hyperaspidinae, for Hyperaspidini plus Brachiacanthini (Duverger 1989; 2001) (Giorgi et al. 2009). In the most recent major contribution to the systematics of Coccinellidae, Kovář (1996) proposed a classification of Coccinellidae worldwide, recognizing seven subfamilies and 38 tribes. Duverger (2003) attempted to apply a distinct subfamily name to each of the 18 major groupings in Kovář 's dendrogram (1996). Many of these names, however, were invalid (based on junior synonyms), misspelled, or applied inconsistently within the different sections of the same paper.
Pope (1989) and Vandenberg (2002) pointed out major caveats in the current classification of Coccinellidae, emphasizing the lack of morphological support for most of the recognized subfamilies. Ślipiński (2007) acknowledged the criticism and proposed a more conservative system, in which only two subfamilies are recognized, Microweiseinae (=Scotoscymninae Duverger =Sticholotidinae sensu Kovář 1996, in part), and Coccinellinae. None of these various classifications has received a universal following (see Table below for alternative classifications).
Many regional taxonomic monographs have been published in the last three decades, including: Fürsch (1967) [European fauna]; Gordon (1985) [North America]; Hoang (1982; 1983) [Vietnam]; Iablokoff-Khnzorian (1982) [Palearctic and Oriental regions]; Kuznetsov (1997) [Russian Far East]; Pang and Mao (1979) [China]; Pope (1989) [Australian Coccinellinae]; Sasaji (1971a) [Japan]; and Savoiskaya (1983) [Central Asia and parts of the former USSR].

Lady beetles come in many different colors and patterns. Mouse over the following words to see more examples below: striped, checkered, banded, ocellate, metallic, punctuation marks, inkblot, radial lines.
The charismatic red and black dappled members of the tribe Coccinellini are easily recognized by the layperson, but the family as a whole is somewhat difficult to characterize. Most species can be identified by the broadly rounded to elongate body form with convex dorsum and flattened venter, clubbed antennae, and the presence of a postcoxal line on the first abdominal ventrite (lacking in Paranaemia, Naemia, and Coleomegilla). The tarsal formula of most species is 4-4-4 with the third tarsomere minute and tucked within the broad triangular second (cryptotetramerous or pseudotrimerous), only a few have the tarsomeres more equal (truly tetramerous), and some have tarsi reduced to 3-3-3 (truly trimerous).
It can be difficult to recognize a lady beetle without studying some of its minute morphological features. The majority of species are very small, drab, and pubescent ("furry") like the image below.

What are their respective vulnerabilities? Coccinellids are quite similar to endomychid beetles, but lack a frontoclypeal suture and have the mandibular mola reduced or absent. They also lack the impressed lines on the base of the pronotum which are characteristic of many endomychids. The family Corylophidae also shares many affinities with Coccinellidae, but Corylophids posess a functional spiracle on abdominal segment 7 (lacking in Coccinellidae), have the galea and lacinia of the mouthparts fused into a single lobe (separate structures in Coccinellidae), and have a distinct form to the male genitalia.

Lady Beetles are found all around the world. There are hundreds of species of lady beetles in North America. Also over a hundred species have been transported between continents by people hoping they would eat aphids and other pests better than the native beetles do.
Biogeographic Regions: nearctic (Introduced , Native ); palearctic (Introduced , Native ); oriental (Native ); ethiopian (Native ); neotropical (Native ); australian (Native )
Adult Lady Beetles are round and small (1-10 mm) long. They are usually colored in some combination of black and red, orange, or yellow, and often have spots on their wing covers. Some species always have the same pattern of colors and spots, but in some species individual beetles can have very different colors. Lady Beetle antennae are short, shorter than the front legs, and are thicker at the ends than the middle. Lady Beetle larvae are also colored in some combination of black and red or orange. They are very active, and have rather rough or bumpy looking bodies that are longer than the adults. Lady Beetle pupae look somewhat like the adults. It is nearly impossible for anybody but experts to tell male Lady Beetles from female ones, and even the experts sometimes can't tell without dissecting the beetle. The bright colors of Lady Beetles are warnings to predators, because all Lady Beetles have toxic chemicals in their blood that makes them taste very bad.
Range length: 1.0 to 10.0 mm.
Other Physical Features: ectothermic ; bilateral symmetry
Sexual Dimorphism: sexes alike
Lady Beetles live where their prey live. This means on plants, mostly herbs and bushes, but sometimes trees or even grass. Species that live in temperate climates with cold winters sometimes make short migrations to warmer habitats, and many spend the winter hiding under bark or in a crack or crevice.
Habitat Regions: temperate ; tropical ; terrestrial
Terrestrial Biomes: taiga ; chaparral ; forest ; rainforest ; scrub forest ; mountains
Wetlands: marsh ; swamp
Other Habitat Features: urban ; suburban ; agricultural
Most lady beetles are voracious predators. A large adult lady beetle can eat 60 Aphididae a day, and even a smaller larva might eat 25. In her lifetime, a female lady beetle might eat 2,500 aphids. Some lady beetles eat other kinds of small, soft-bodied Insecta that are related to aphids. A very few species eat fungal spores, and there are three species in North America that eat plants. One of them is a significant agricultural pest; it eats the leaves of bean plants. A few lady beetles eat pollen, especially early in the spring when there aren't many aphids to eat.
Some Lady Beetle species are important predators on aphids and other insects.
All lady beetles have "reflex bleeding." This means that when they are attacked they automatically leak some of their blood out from joints in their legs and other parts of their body. Their blood has toxic chemicals in it, and tastes bad to predators. Their bright colors are probably a warning to predators that they taste bad. Lady beetle larvae often go away from their food supply and hide to pupate. This may help them avoid other predators.

Life History and Behavior
Communication and Perception
Lady Beetle communicate with each other mainly with chemicals.
Lady Beetles have the same life stages as other beetles (see More Information on the Beetle page). Lady Beetle larvae are more active than many other kinds of beetles. Lady Beetles spend the winter as adults, and lay their eggs in the following summer. The larvae eat a lot and grow fast, and emerge as adults in the late summer or fall.
Development - Life Cycle: metamorphosis
Lady Beetles usually live less than two years.
Female Lady Beetles lay hundreds of eggs, sometimes over 2,000. They usually lay them near aphids or other prey insects, so the newly hatched beetle larvae will have food right away.
Breeding season: Summer
Key Reproductive Features: iteroparous ; seasonal breeding ; sexual ; fertilization (Internal ); oviparous
Lady Beetles don't show much parental care. Once the female finds a good place to lay her eggs, she lays them and then leaves.
Parental Investment: no parental involvement
Evolution and Systematics
Discussion of Phylogenetic Relationships
Coccinellidae and the Cerylonid Series
Molecular evidence supports Coccinellidae as belonging to the Cerylonid Series (Hunt et al., 2007; Robertson et al., 2008) but the closest relative of the family remains unclear. Early morphological studies supported hypotheses that the sister-group was a clade comprising Endomychidae plus Corylophidae (Crowson, 1981; Sasaji, 1971) or one comprising Endomychidae plus Alexiidae (Pakaluk and Ślipiński, 1991). These studies, however, were not based on formal phylogenetic analyses.
Formal phylogenetic studies that provide insights about the closest relatives of Coccinellidae resulted, each, in different answers. In these studies, the following taxa were recovered as close relatives of Coccinellidae: Endomychidae (Tomaszewska, 2000), Anamorphinae (Endomychidae) plus Alexiidae (Hunt et al., 2007), Corylophidae (Tomaszewska, 2005), Leiestinae (Endomychidae) (Robertson et al. 2008, parsimony) and Endomychidae minus Anamorphinae or Corylophidae plus Anamorphinae (Robertson et al. 2008, Bayesian). Since each of these studies addressed different phylogenetic questions, the taxonomic sampling was fairly different, which might account for the noted disparities.
Sasaji (1968, 1971) provided the first attempt to address the higher-level phylogenetic relationships of Coccinellidae (see fig. below). Under Sasaji’s classical phylogenetic scheme, three main branches are recognized. At the base is the subfamily Sticholotidinae, considered the most primitive group of coccinellids. On the main branch, one lineage includes the subfamilies Scymninae and Chilocorinae, and other includes Coccidulinae, Coccinellinae and Epilachninae. In the latter group, Coccidulinae was considered the sister group to the coccinelline plus epilachnine branch.
Kovář’s (1996) hypothesis was very similar to Sasaji’s (1968, 1971), differing only in placing Coccidulinae at the base of the scymnine plus chilocorine branch. He also recognized a seventh subfamily, Ortaliinae, comprised of the former Coccidulinae tribe, Noviini, and the former Scymninae tribe, Ortaliini.
In spite of the relevance of these contributions, both Sasaji (1968, 1971) and Kovář’s (1996) studies have some limitations. In both studies the hypotheses were not generated by formal phylogenetic methods, thus none of the clades are supported by synapomorphies. Sasaji’s study did not include any neotropical coccinellids, being mostly restricted to the Japanese fauna. Kovář’s (1996) study was more comprehensive in terms of diversity.
The first formal cladistic analysis was conducted by Yu (1994). His study used adult and larval morphological characters. The partitions (adults vs. larvae) were treated separately, and produced drastically conflicting topologies. The adult-based topology had few points of agreement with previous hypotheses. Yu (1994) recovered all Sticholotidinae at the base, but not as a monophyletic group. As with Sasaji’s (1968) hypothesis, this study supports a clade containing the subfamilies Chilocorinae, Coccidulinae and Scymninae, but none of these subfamilies were recovered as monophyletic. Coccidulinae was recovered as paraphyletic with respect to Ortaliinae, Chilocorinae, and Scymninae. Chilocorinae and Ortaliinae were nested within Scymninae. The sister group relationship between Epilachninae and Coccinellinae was not supported in this study. Epilachninae diverged from the rest of the family at the next highest node, followed by Coccinellinae. A close relationship between Serangiini and Sukunahikonini was the only point of similarity between the adult and larval topologies.
Giorgi et al. (2009) conducted a parsimony analysis using the nuclear ribosomal genes 18S rDNA and 28S rDNA to address the evolution of food preferences in Coccinellidae. As in the previous studies, the subfamily Sticholotidinae was supported as the sister group of the rest of the coccinellids, but only in part. Other Sticholotidinae included in the analysis, were supported as more advanced forms. The resulting topology of this study disagrees with Sasaji’s (1968) classic hypothesis in many points. Unfortunately the relationships between most of the major branches were not strongly supported.
Thus, an accurate definition of the main lineages of coccinellids as well as the relationships between them still remains to be established.

No Lady Beetles species are legally protected, and most are abundant and don't need special conservation. However, some native species have been disappearing at the same time that species from othe continents have arrived or been released. The invaders may be pushing the natives out.
Relevance to Humans and Ecosystems
Economic Importance for Humans: Negative
A very few Lady Beetles eat plants we grow for food. Also, Lady Beetles sometimes accidentally hibernate in people's houses or other buildings. A few Lady Beetles may bite, but mainly by accident (you have some chemical on you that tastes good) or to defend themselves. The bite is not dangerous and doesn't hurt much.
Negative Impacts: injures humans (bites or stings); crop pest; household pest
Economic Importance for Humans: Positive
Nearly all Lady Beetle species eat insects that are pests. Sometimes Lady Beetles can be very helpful in controlling pests on farms and in gardens
Positive Impacts: controls pest population
The Coccinellidae (//) .) are a family of small beetles, ranging from 0.8 to 18 mm (0.0315 to 0.708 inches). They are commonly yellow, orange, or scarlet with small black spots on their wing covers, with black legs, heads and antennae. Such colour patterns vary greatly, however; for example, a minority of species, such as Vibidia duodecimguttata, a twelve-spotted species, have whitish spots on a brown background. Coccinellids are found worldwide, with over 5,000 species described.
Coccinellidae are known colloquially as ladybirds (in Britain, Ireland, the Commonwealth, and some parts of the southern United States), ladybugs (originating in North America) or lady cows, among other names. When they need to use a common name, entomologists in the United States widely prefer the names ladybird beetles or lady beetles as these insects are not true bugs.
The Coccinellidae are generally considered useful insects, because many species feed on aphids or scale insects, which are pests in gardens, agricultural fields, orchards, and similar places. Within the colonies of such plant-eating pests, they will lay hundreds of eggs, and when these hatch the larvae will commence feeding immediately. However, some species do have unwelcome effects; among these, the most prominent are the subfamily Epilachninae, which are plant eaters. Usually, Epilachninae are only mild agricultural pests, eating the leaves of grain, potatoes, beans, and various other crops, but their numbers can increase explosively in years when their natural enemies, such as parasitoid wasps that attack their eggs, are few. In such situations, they can do major crop damage. They occur in practically all the major crop-producing regions of temperate and tropical countries.
Coccinellid is derived from the Latin word coccineus meaning "scarlet". The name "ladybird" originated in Britain where the insects became known as 'Our Lady's bird' or the Lady beetle. Mary (Our Lady) was often depicted wearing a red cloak in early paintings, and the spots of the seven-spot ladybird (the most common in Europe) were said to symbolise her seven joys and seven sorrows. In the United States, the name was adapted to "ladybug". Common names in other European languages have the same association, for example, the German name Marienkäfer translates to Marybeetle.
Most coccinellids have oval, dome-shaped bodies with six short legs. Depending on the species, they can have spots, stripes, or no markings at all. Seven-spotted coccinellids are red or orange with three spots on each side and one in the middle; they have a black head with white patches on each side.
As well as the usual yellow and deep red colourings, many coccinellid species are mostly, or entirely, black, dark grey, gray, or brown, and may be difficult for an entomologist/nonentomologists to recognise as coccinellids at all. Conversely, non-entomologists might easily mistake many other small beetles for coccinellids. For example, the tortoise beetles, like the ladybird beetles, look similar because they are shaped so that they can cling to a flat surface so closely that ants and many other enemies cannot grip them.
Non-entomologists are prone to misidentify a wide variety of beetle species in other families as "ladybirds", i.e. coccinellids. Beetles are particularly prone to such misidentification if they are spotted in red, orange or yellow and black. Examples include the much larger scarabaeid grapevine beetles and spotted species of the Chrysomelidae, Melyridae and others. Conversely, laymen may fail to identify unmarked species of Coccinellidae as "ladybirds". Other beetles that have a defensive hemispherical shape, like that of the Coccinellidae (for example the Cassidinae), also are often taken for ladybirds.
A common myth, totally unfounded, is that the number of spots on the insect's back indicates its age. In fact, the underlying pattern and colouration are determined by the species and genetics of the beetle, and develop as the insect matures. In some species its appearance is fixed by the time it emerges from its pupa, though in most it may take some days for the colour of the adult beetle to mature and stabilise. Generally, the mature colour tends to be fuller and darker than the colour of the callow.
Coccinellids are best known as predators of Sternorrhyncha such as aphids and scale insects, but the range of prey species that various Coccinellidae may attack is much wider. A genus of small black ladybirds, Stethorus, presents one example of predation on non-Sternorrhyncha; they specialise in mites as prey, notably Tetranychus spider mites. Stethorus species accordingly are important in certain examples of biological control.
Various larger species of Coccinellidae attack caterpillars and other beetle larvae. Several genera feed on various insects or their eggs; for example, Coleomegilla species are significant predators of the eggs and larvae of moths such as species of Spodoptera and the Plutellidae. Larvae and eggs of ladybirds, either their own or of other species, can also be important food resources when alternative prey are scarce. As a family, the Coccinellidae used to be regarded as purely carnivorous, but they are now known to be far more omnivorous than previously thought, both as a family and in individual species; examination of gut contents of apparently specialist predators commonly yield residues of pollen and other plant materials. Besides the prey they favour, most predatory coccinellids include other items in their diets, including honeydew, pollen, plant sap, nectar, and various fungi. The significance of such nonprey items in their diets is still under investigation and discussion.
Apart from the generalist aphid and scale predators and incidental substances of botanical origin, many Coccinellidae do favour or even specialise in certain prey types. This makes some of them particularly valuable as agents in biological control programmes. Determination of specialisation need not be a trivial matter, though; for example the larva of the Vedalia ladybird Rodolia cardinalis is a specialist predator on a few species of Monophlebidae, in particular Icerya purchasi, which is the most notorious of the cottony cushion scale species. However, the adult R. cardinalis can subsist for some months on a wider range of insects plus some nectar.
Certain species of coccinellids are thought to lay extra infertile eggs with the fertile eggs, apparently to provide a backup food source for the larvae when they hatch. The ratio of infertile to fertile eggs increases with scarcity of food at the time of egg laying. Such a strategy amounts to the production of trophic eggs.
Some species in the subfamily Epilachninae are herbivores, and can be very destructive agricultural pests (e.g., the Mexican bean beetle). Again, in the subfamily Coccinellinae, members of the tribe Halyziini and the genus Tythaspis are mycophagous.
While predatory species are often used as biological control agents, introduced species of coccinellids are not necessarily benign. Species such as Harmonia axyridis or Coccinella septempunctata in North America outcompete and displace native coccinellids and become pests themselves.
The main predators of coccinellids are usually birds, but they are also the prey of frogs, wasps, spiders, and dragonflies. The bright colours of many coccinellids discourage some potential predators from making a meal of them. This phenomenon, called aposematism, works because predators learn by experience to associate certain prey phenotypes with a bad taste. A further defence, known as "reflex bleeding", exists in which an alkaloid toxin is exuded through the joints of the exoskeleton, triggered by mechanical stimulation (such as by predator attack) in both larval and adult beetles, deterring feeding.
Coccinellids in temperate regions enter diapause during the winter, so they often are among the first insects to appear in the spring. Some species (e.g., Hippodamia convergens) gather into groups and move to higher elevations, such as a mountain, to enter diapause.
Most coccinellids overwinter as adults, aggregating on the south sides of large objects such as trees or houses during the winter months, dispersing in response to increasing day length in the spring.
Predatory coccinellids are usually found on plants which harbour their prey. They lay their eggs near their prey, to increase the likelihood the larvae will find the prey easily. In Harmonia axyridis, eggs hatch in three to four days from clutches numbering from a few to several dozen. Depending on resource availability, the larvae pass through four instars over 10–14 days, after which pupation occurs. After a teneral period of several days, the adults become reproductively active and are able to reproduce again, although they may become reproductively quiescent if eclosing late in the season. Total life span is one to two years on average.
Infestations and impacts
In the United States, coccinellids usually begin to appear indoors in the autumn when they leave their summer feeding sites in fields, forests, and yards and search out places to spend the winter. Typically, when temperatures warm to the mid-60s F (around 18 °C) in the late afternoon, following a period of cooler weather, they will swarm onto or into buildings illuminated by the sun. Swarms of coccinellids fly to buildings in September through November depending on location and weather conditions. Homes or other buildings near fields or woods are particularly prone to infestation.
After an abnormally long period of hot, dry weather in the summer of 1976 in the UK, a marked increase in the aphid population was followed by a "plague" of ladybirds, with many reports of people being bitten as the supply of aphids dwindled.
As an alien species
Harmonia axyridis (the harlequin ladybird) is an example of how an animal might be partly welcome and partly harmful. It was introduced into North America from Asia in 1916 to control aphids, but is now the most common species, outcompeting many of the native species. It has since spread to much of western Europe, reaching the UK in 2004. It has become something of a domestic and agricultural pest in some regions, and gives cause for ecological concern. It similarly has turned up in parts of Africa, where it has proved variously unwelcome, perhaps most prominently in vine-related crops.
UK ladybird survey
The atlas Ladybirds (Coccinellidae) of Britain and Ireland published in 2011 showed a decline of more than 20% in native species due to environmental changes and competition from foreign invaders. The distribution maps, compiled over a 20-year period with help from thousands of volunteers, showed a decline in the numbers of the common 10-spot and 14-spot ladybirds and a number of other species, including the 11-spot, 22-spot, cream-spot, water and hieroglyphic ladybirds, Coccidula rufa, Rhyzobius litura and Nephus redtenbacheri. Conversely, increases were seen in the numbers of harlequin, orange, pine, and 24-spot ladybirds, as well as Rhyzobius chrysomeloides. The kidney spot ladybird was recorded in Scotland for the first time in recent years, and the 13-spot was found to have recolonised Cornwall, Devon, and the New Forest. The most commonly recorded species was the 7-spot, closely followed by the Asian harlequin — an invader that arrived from continental Europe in 2003 after being introduced to control pests. An 'explosion' in the number of orange ladybirds, which feed on mildew, is thought to have been due to the warmer, damper conditions that now prevail in parts of England.

In popular culture
Coccinellids are, and have been for very many years, a favourite insect of children. The insects had many regional names (now mostly disused) in English, such as the lady-cows, may-bug, golden-knop, golden-bugs (Suffolk); and variations on Bishop-Barnaby (Norfolk dialect) – Barnabee, Burnabee, the Bishop-that-burneth, and bishy bishy barnabee. The etymology is unclear, but it may be from St. Barnabas' feast in June, when the insect appears, or a corruption of "Bishop-that-burneth", from the fiery elytra of the beetles.

She was flying over a green meadow.Fly to the sky, little ladybird, bring me a piece of bread.
A little spider caught her in its spiderweb
I will set you free, little ladybird, and you bring me something.
Many cultures consider coccinellids lucky and have nursery rhymes or local names for the insects that reflect this. For instance, the Turkish name for the insect is uğur böceği, literally meaning "good luck bug". In many countries, including Russia, Turkey, and Italy, the sight of a coccinellid is either a call to make a wish or a sign that a wish will soon be granted.
In Christian areas, coccinellids are often associated with the Virgin Mary and the name that the insect bears in the various languages of Europe corresponds to this. Though historically many European languages referenced Freyja, the fertility goddess of Norse mythology, in the names, the Virgin Mary has now largely supplanted her, so that, for example, freyjuhœna (Old Norse) and Frouehenge have been changed into marihøne (Norwegian) and Marienkäfer (German), which corresponds with Our Lady's bird. Sometimes, the insect is referred to as belonging directly to God (Irish bóín Dé, Polish boża krówka, all meaning "God's [little] cow"). In Dutch it is called lieveheersbeestje, meaning "little animal of our Good Lord".
In both Hebrew and Yiddish, it is called "Moshe Rabbenu's (i.e. Moses's) little cow" or "little horse", apparently an adaptation from Slavic languages. Occasionally, it is called "little Messiah".
