General Ecology

Overwintering males and females generally emerge from the nest in May, with males somewhat earlier. Mating is followed by the female foraging phase. Nests, usually made in old carpenter bee borings, are provisioned with caterpillars. As each cell is filled, the female lays an egg and seals the cell with a mud partition before beginning the next. Those larvae that complete development early enough will emerge in mid-summer. However, those established later will not emerge until the following year. Hence, this species is semibivoltine. In west central Illinois, activity continues until mid-September (Edgar & Coelho, 2000).

Monobia quadridens

Monobia quadridens is a species of solitary potter wasp found in North America. It grows to a wingspan of 18 millimetres (0.71 in), and feeds on small caterpillars and pollen. There are two generations per year, with one generation overwintering as pupae.

Description[edit]

The abdomen of M. quadridens is entirely black, except for a broad ivory-coloured band on the first tergite.[2] The wingspan is typically 11–14.5 millimetres (0.43–0.57 in) for males, and 14–18 mm (0.55–0.71 in) for females.[2] It closely resembles Euodynerus bidens in size and colouration.[2]

Distribution[edit]

Monobia quadridens has a wide distribution in eastern North America. In Mexico, it is found in the states of Tamaulipas and Nuevo León, while in the United States, it is found from New Mexico, Kansas and Wisconsin east to the Eastern Seaboard.[2] The occurrence of the species in Canada has not been explicitly recorded in print, but specimens identified as M. quadridens have been present in Canadian entomological collections for a long time.[2]

Life cycle and ecology[edit]

Monobia quadridens is bivoltine, having two generations in a year. One emerges in summer, while the other overwinters as a pupa before emerging the following spring.[3] Copulation lasts for 30 minutes in M. quadridens, while in most wasp species, it only lasts a minute or two.[4] It nests in a variety of cavities including tunnels abandoned by carpenter bees, old mud dauber nests and hollow plant stems.[2]

The diet of M. quadridens is primarily composed of caterpillars of microlepidoptera, including species from the families Pyralidae, Crambidae, Elachistidae, Amphisbatidae, Gelechiidae and Tortricidae.[2] The diet also includes a large proportion of pollen.[5]

Sting[edit]

Like many wasps, Monobia quadridens is capable of delivering a sting. The pain caused by the sting of a female is similar to that caused by the bald-faced hornet or the ant Myrmecia nigripes.[6] Unlike most other wasps, however, the male is also capable of delivering a painful sting like a needle prick, although no venom is injected, so the pain is transient. The male has no stinger and uses the tip of its abdomen.[7]

Taxonomy[edit]

Monobia quadridens was first described by Carl Linnaeus in his 1763 work Centuria Insectorum, under the name Vespa quadridens.[8]
