Trichrysis cyanea is a species of cuckoo wasps, insects in the family Chrysididae.
Distribution[]
This species is widespread in most of Europe and northern Africa throughout the Palearctic realm (central Asia, Siberia, Korea, China, and Japan).[1][2][3]
Habitat[]
These wasps inhabit forest margins, clearings and areas with sun-exposed dead trees and tree stumps, usually nesting sites of its hosts.[3]
Description[]
Trichrysis cyanea can reach a body length of about 4–8 mm (0.16–0.31 in). These small sized cuckoo wasps have an elongated and completely blue-green or violet colored body, but males are often completely or partly black.[3] The posterior margin of the third tergite of the abdomen shows three small wide teeth. The first tergite has a smooth middle furrow.[3]
This species is very similar to the species of the genus Chrysis.
Biology[]
The adults can be found in several generations from May to October, but mainly during June and July.[3] These wasps parasitizes mainly on wasps of the group and (Crabronidae), but also Auplopus carbonarius and species of Dipogon (Pompilidae). Other recorded hosts are , , , , Ancistrocerus, , , , , , , , and Chelostoma florisomne.[2][3][4]
The female lays her egg at different times of nest building. The larvae are well recognizable by its gray-green body and brightly colored head and abdomen. Over the next five days, the larvae feed on the food supply. The pupation takes place in a shining golden brown cocoon. The development of the imago lasts 17 to 23 days. Larvae usually overwinter.[5]
