I've been amazed by the diversity of #Diapriidae #wasps in my #Malaise trap in #Canberra. The genus #Rostropria is a particular favourite.

Here are three images of female Rostropria spiniventris and one of Rostropria simplex.

Early & Naumann 1989 recorded the same two species from the ACT, butonly found brachypterous/micropterous females of spiniventris.

3 out of 5 of my ♀ spiniventris have been macropterous. Is wing length controlled by development environment?

I shared Acanthobetyla cerbera (same location):

Differences include rounded/emarginate forewings, spines/carina on vertex and metanotal carina.

Any #iNaturalist users able to verify?

I ran a #Malaise trap run in my garden for two years (2020-10-23 to 2022-10-28). The first year's samples went to the Centre for Biodiversity Genomics in Guelph, ON for DNA barcoding. In the second year, I've been focused mostly on #Ichneumonidae and other parasitic wasps. #entomology

Three insects from 12-19 Aug 2022: #Acanthobetyla cerbera (#Diapriidae, 2 images), #Elateridae sp. and probably #Anacis sp. (#Ichneumonidae).
