I believe this is Pteromalidae - update: Scelionidae
Racine, Racine County, Wisconsin, USA
March 28, 2009
Size: 2.5mm
Is there any way of telling species from an ?embryo? Sorry...I know nothing about wasps. It was found in a Prickly Ash twig amongst Oecanthinae egg cases. Scelionids are known to be egg parasites. Note how this specimen has an outline of an Oecanthinae egg. (Apparently Pteromalidae are known to be parasites of Oecanthus niveus. They may parasitize other species of tree crickets, but my only reference at this point is an 1884 publication. The publication mentions Teleas, but is this another Family? Online info indicates teleas is a grasshopper parasite.)

I'll watch for newer specimens this season to get better photos.

This specimen was examined by an expert
...and was determined to be a Scelionidae. Note how its shape matches that of an Oecanthinae egg. I'm assuming this wasp did not emerge last season. (?)

Great!
Glad to see it has been at least identified to this level.
