A Puzzlement
Sewanee, Franklin County, Tennessee, USA
June 2, 2013
Size: 1/2-3/4"
I don't have any idea what this is. I found it on Virginia Meadow Beauty, with tiny flying things on it. Are they parasites? Is this some kind of egg case?

Wasps…
Appears to be chalcid wasps - do you have any close-ups?

Close-ups?
This is as close to a close-up as my camera can accomplish. This was tiny -- about 1/2 an inch from bottom to top.

Re: wasp parasitoids…
Besides chalcids, tabanid eggs are also attacked by Platygastrids, in particular Telenomus which are only about 1mm in length. Certainly a possibility here.

Thanks!
That's definitely tiny!

i think this is
some sort of (maybe horsefly) eggs with parasitic wasps laying eggs on them.
