Moved from Cleonyminae.


Hymenoptera (Pteromalidae)
This is a great catch. It is a female of Oodera sp. (Pteromalidae: Cleonyminae: Ooderini). Oodera is an Old World genus, but one species was introduced accidentally into the USA. We still are uncertain as to its correct species name. It has previously been collected only from eastern USA (MD, NJ, VA) where it was reared once from Gleditsia (Fabaaceae). Old World insect hosts include wood-boring beetles (Buprestidae and Scolytidae). It is a strange looking beast with raptorial front legs, for which no one knows the actual function. Also, notice the transverse grey area across the thorax. In at least museum specimens the mesoscutum often breaks in this general area, which has occurred in this specimen. Presumably, when a specimen dries out after death there is quite a bit of tension on the mesoscutum so that it can break. However, I have never seen a live specimen. Did you capture only a single one?

Thank you very much
for all the information.
I'm sorry to say that it will take me years to go through the 3 Malaise traps I set in 2007-2008. Because this individual was distinctive, it got pulled.
I do plan on working on these again so will start with this location and date. I'll offer this specimen to you, but I'll have to find it first.
