Dustywing parasitoid - Dendrocerus conwentziae

Dustywing parasitoid - Dendrocerus conwentziae
Pelham, Hampshire County, Massachusetts, USA
June 7, 2011
Size: 1.4 mm
Emerged yesterday from a coniopterygid cocoon I collected from leaf litter on 5/1/2011. This strikes me as very different from any wasp I've seen before. The 1979 Catalogue of Hymenoptera mentions that some species of Dendrocerus (Megaspilidae) parasitize coniopterygids; the only other coniopterygid parasitoid listed is Trjapitzinellus microrphanos (Ichneumonidae) in California, unless there are other coniopterygid hosts listed only by genus/species (I just did a search for "Coniopt").

Moved from Dendrocerus.
ID confirmed by István Mikó upon examining the specimen.

Thanks Andy!

Dendrocerus sp.
From my colleague here at NCSU (István Mikó): "The species is most probably D. conwentziae Gahan 1919, that has been reared from Conwentzia sp. and Coniopteryx vicina. This is one of the most common Nearctic Dendrocerus species in the [Smithsonian] collection..."

Moved from "Parasitica" (parasitic Apocrita).
Great, thanks! My first ceraphronoid!

Megaspilid…
This does match the description for this group. Some dipteran and hymenopteran hyperparasitoids are mentioned in the literature. Will check further.

Found a reference here that species of the genus Dendrocerus are either primary parasitoids of Neuroptera and Diptera, or hyperparasitoids of Homoptera and Coleoptera through various Hymenoptera. Several species of Dendrocerus are mentioned as emerging from cocoons of Coniopterygidae. So this may indeed have been a primary parasitoid of the dustywing.
