Are these wasps? Trichogrammatidae? - Trichogramma

Corvallis, Benton County, Oregon, USA
September 27, 2012
Size: very tiny

Noticed white eggs in clusters on thin plastic netting used as a deer-deterrent fence. On much closer inspection, I saw many hatched eggs in one cluster and in that area, several of these tiny creatures milling around the eggs. After browsing the site I thought they might be parasitic wasps. To give a proper sense of scale, I took these photos with a macro lens on 3 extension tubes. It's been a few months since I took the photos but I don't think these guys were larger than 1mm.

Trichogramma sp. --det. J.D. Pinto

his comment: "If find more place them in 90% EtOH. It would be possible to get a species identification."

Moved from Trichogrammatidae.

Moved from "Parasitica" (parasitic Apocrita).
They are noctuid eggs.

Yes…

This is, indeed, this family. Features such as the 3-segmented tarsi, shortened antennae, and wide wings with a short marginal fringe can be seen in these images. The eggs may be those of moths which are heavily targeted by many species. These are among the smallest of insects, some measuring less than 0.2 mm in length.

Nice work, Jacqueline.
