Glyptapanteles? - Microplitis

Glyptapanteles? - Microplitis
Pine Brook, Isanti County, Minnesota, USA
June 10, 2020
Size: TBL ~ 4 mm
The wasp was found eclosed on the morning of June 10. The caterpillar still showed similar reflexive responses. I don't know how helpful my images will be but I do have the wasp should anyone wish to examine it.

Moved from Microgastrinae.

Microplitis…
Great images, very clear. It is, 100% sure, the genus Microplitis.

Now, there are 3 species previously recorded as parastizing Amphipyra (although none quite match your images). The most interesting thing is that there are no records of any Microgastrinae previously parastizing A. pyramidoidescase. That means it is a new host record.

See reference here.

 
Thank you!
I'm pretty sure there are several images of a microgastrine cocoon in the 'care' of an Amphipyra pyramidoides caterpillar posted by at BG. See photos 399419, 1190224, and 894890 (you commented on this last one). Interestingly, the cocoons seem to be held crosswise rather than along the line of the caterpillar as mine was.
Then again, maybe these are not microgastrine cocoons?

re: Microgastrinae…
This is not Glyptapanteles due to the presence of a closed areolet in the wing. If you can provide a closeup dorsal view of the propodeum and first metasomal tergite, this might be helpful for a genus ID.

 
Thanks Ross,
I don't know if I can achieve that, but will give it a try.

 
Genus ID...
Thanks for these additional images. I will ask Dr. Triana for his comments on this wasp.

 
Thanks much!
Thanks much!
