Life History and Behavior
Although Notodontidae are an important component of some moth communities, especially in lowland tropical forests, almost nothing is known about their adult behavior. Females are usually heavy-bodied and do not seem to stray far from their host plant. Perhaps because notodontids are rarely plant pests, their pheromones have not been isolated and their mating behavior has gone essentially unstudied. Males of most species possess highly developed coremata on their genitalia, termed the Barth Organ (Barth, 1955; Weller, 1992). While these are undoubtedly important during courtship, their use has never been documented in nature. Females of some species, particularly in the Thaumetopoeinae and Dioptinae, posses a corethrogyne, comprising a mass of deciduous scales on abdominal segment 7 that are pasted to the surface of the eggs as these are being laid. The corethrogyne is thought to protect the eggs from predators and parasites. Many adult notodontids possess prominent tufts on their head, thorax, wings, or abdomen (see Schintlmeister, 2008). These make the moths incredibly cryptic, causing it to bear remarkable resemblance to a stick or small twig when at rest.
Life History: Immature Stages
Life History: Adults
In most subfamilies of the Notodontidae, adults have rarely been observed feeding or visiting flowers. Those with a reduced haustellum (mostly subfamily Notodontinae) do not feed, but probably imbibe water opportunistically. The notodontine genus Gluphisia has been shown to use its small proboscis as a filter, sucking up huge quantities of water from puddles to obtain sodium (Smedley and Eisner, 1995). Species of Euchontha, in the subfamily Dioptinae, are frequently observed puddling (Miller, 2009), also apparently to acquire sodium. These moths often appear amongst huge congregations of puddling butterflies. Dioptines, most of which are diurnal, are atypical in that adults are often seen feeding on nectar [see whole organism image gallery].
Life history adult:
The vast majority of notodontid species are nocturnal and are strongly attracted to lights. In nocturnal forms their metathoracic hearing organ can supposedly detect bat cries (Fullard et al., 2000), whereas in Dioptinae tympanal function seems to have become co-opted for detecting intraspecific sounds produced by a stridulatory organ on the male forewing (Miller, 2009). Little is known regarding the life span of adult Notodontidae.
Life cycle description:
Eggs of Notodontidae are hemispherical or spherical, weakly sculptured, and the micropyle opens dorsally. They are usually deposited singly, but in some taxa are laid in tight masses. Notodontid larvae are well adapted to an arboreal habit, but are generally not capable of rapid locomotion (Ferguson, 1963). Caterpillars of most species possess a prothoracic cervical gland that opens midventrally. This gland is defensive and is capable of spraying formic acid, sometimes for fairly long distances. In the vast majority of Notodontidae, the A10 larval prolegs are reduced and are held aloft. In certain genera, the A10 prolegs are developed into long, whip-like structures called stemapods. Most species pass through five or six larval instars, but members of the tribe Josiini (Dioptinae) are unique in having only four. Caterpillars of the Dicranurinae (formerly Heterocampinae) undergo remarkable changes during development. For example, first instars of Heterocampa bear huge, antler-like structures on the prothorax (Packard, 1895); these are lost in subsequent instars. Pupae are usually formed in an earthen cell or in a cocoon, often in leaf litter. The often colorful pupae of Dioptinae are unusual in being suspended by the cremaster from a plant leaf, in the exposed manner typical of butterflies.
Evolution and Systematics
Systematic and taxonomic history
The Notodontidae was treated as a separate superfamily, the Notodontoidea, by some previous authors (d’Almeida, 1932; Kiriakoff, 1970a, 1970b; Pinhey, 1975; Common, 1979; Tikhomirov, 1981; Barlow, 1982). However, more recently it is considered a noctuoid family, sister to the Doidae, with Doidae + Notodontidae being the sister clade to the remaining noctuoid families (Mitchell et al., 2006; Fibiger and Lafontaine 2005; Lafontaine and Fibiger, 2006). Thaumetopoeidae, Dioptidae, and Thyretidae have either been treated as separate families, or have been included within either the Notodontidae or Notodontoidea (Kiriakoff, 1963). However, Thyretidae are now a tribe placed within the Arctiidae (Jacobson and Weller, 2002), and the remaining two are notodontid subfamilies (Kitching and Rawlins, 1999). Druce (1897) was the first to classify the world Notodontidae. He divided the family into three families: Ptilodontidae, Melalophidae (= Pygaerinae), and Eupterotidae (= Apatelodidae) (Miller, 1991). Presently, the Apatelodidae is considered to be a family in the Bombycoidea (Forbes, 1939a; Franclemont, 1983). Other workers have treated portions of the notodontid fauna on a regional basis, generating generic and species diagnoses, keys, and checklists (e.g., Druce, 1887; Schaus, 1901; Draudt, 1932; Forbes, 1948; Franclemont, 1983; Godfrey and Appleby, 1987). The first cladistic analysis of notodontid genera was published by Weller (1989). That study focused on the evolutionary relationships of genera in the Neotropical tribe Nystaleini. Cladistic studies based on morphological characters support a monophyletic Notodontidae (Miller, 1991). Presently, 9 subfamilies are recognized: Thaumetopoeinae, Pygaerinae, Platychasmatinae, Notodontinae, Phalerinae, Dudusinae, Heterocampinae, Nystaleinae, and Dioptinae (see Miller 1991 for subfamily descriptions). A key to all Noctuoidea families with trifid forewing venation is provided by Miller (1991).
One fossil genus known, Cerurites, described by Kernbach in 1967. Type specimens are in Germany (Willershausen).

Notodontidae is a family of moths with approximately 3,800 known species. Moths of this family are found in all parts of the world, but they are most concentrated in tropical areas, especially in the New World (Miller, 1992). The Thaumetopoeidae (processionary moths) are sometimes included here as a subfamily.
Species of this family tend to be heavy-bodied and long-winged, the wings held folded across the back of the body at rest. They rarely display any bright colours, usually being mainly grey or brown, with the exception of the Dioptinae subfamily (Grimaldi and Engel, 2005). These features mean they rather resemble Noctuidae although the families are not closely related. The adults do not feed. Many species have a tuft of hair on the trailing edge of the forewing which protrudes upwards at rest. This gives them the common name of prominents. The common names of some other species reflect their hairiness, such as Puss Moth and the group commonly known as kittens (Furcula spp.), so named as they resemble small versions of the Puss Moth.
The egg is hemisperical or almost spherical, and lacks any ribs (Scoble, 1995).
The caterpillars are usually hairless, but may have tubercules, spines, or humps (Scoble 1995), and often rest with both ends raised. The last set of prolegs is frequently vestigial, or may be long, with glands that can be everted. Some larvae undergo shape modification and colour changes with each instar (Weller, 1992). Notodontid larvae are notable for their often bizarre shapes, and some have chemical defenses (cyanic acid, formic acid, and other ketones: Blum, 1981) not commonly found in other Lepidoptera (Weller 1992). Schizura unicornis and S. badia have a mixture of formic acid, acetic acid and other compounds which they spray accurately at their attacker (Attygalle et al., 1993).
The larvae of some species are truly extraordinary: That of the Puss Moth has a fearsome-looking "face" and two long whip-like "tails" (actually highly modified prolegs) and it rears both ends in a threatening display when disturbed. The larva of the Lobster Moth is even more remarkable, resembling a crustacean. Others, such as Cerura vinula mimic the edge of a leaf that has been damaged and is turning brown (they rest and feed along the edge of the leaf).
Most are solitary feeders, but some are gregarious, and this is most common in the processionary moths, Thaumetopoeinae.
They feed on trees and shrubs, except in the subfamily Dioptinae, which feed on herbaceous plants (Miller, 1992). The larvae typically feed on only one family of trees, but closely related species will feed on distantly related plants; for example different members of the genus Datana feed on Juglandaceae, Hamamelidaceae, Ericaceae and Anacardiaceae (Miller 1992).
Adults have tympanal organs on the metathorax that opens towards the top, and the tibial spurs have serrated edges (Scoble, 1995). Mouthparts vary from well-developed to absent. The Dioptinae, which was formerly considered a separate family, are colourful and fly by day, while the rest of the notodontids are nocturnal. Some of these Dioptinae have non-functional tympanal hearing organs which are normally defensive against bats (Fullard et al., 1997).
Some notodontids cause noticeable defoliation of their hosts. Well-known defoliators include: the saddled prominent Heterocampa guttivita, poplar defoliator Clostera cupreata, California oakworm Phryganidia californica, the beech caterpillar, Quadricalcarifera punctatella, variable oakleaf caterpillar Lochmaeus manteo, Epicerura pergisea, yellownecked caterpillars Datana ministra, and walnut caterpillar Datana integerrima, among others.
Notable species are:
- Buff-tip (Phalera bucephala)
- Puss Moth (Cerura vinula)
- Lobster Moth (Stauropus fagi)
- Poplar Kitten (Furcula bifida)
- Coxcomb Prominent (Ptilodon capucina)
- Rough Prominent (Nadata gibbosa)
Apart from the subfamilies listed above, there are numerous notodontid genera of uncertain relationships. These are:
