Fly or wasp? on Eggs - Trissolcus

Fort Bragg, Cumberland County, North Carolina, USA
September 14, 2005

I found these eggs on a car that had been under a tarp. They were in close proximity to a jumping spider....but don't think that matters. This wasp was attending the eggs the entire time I was taking pictures.

New mother

This may be one of the Scelionidae, which is in Hymenoptera, and they are common egg parasites of a diverse group of egglayers. (At least seven different orders.) The mothering wasps often do stay with the parasitized eggs until they are emergent, mostly to keep other egg parasites away. She likely parasitized every egg in this array. Very diverse in body form, these little gals can be very common at the end of summer when egg numbers are at a peak. Nice shots.

Egg guarding

Do other chalcid egg parasitoids do this?

This encyrtid was wandering around on a white-marked tussock moth egg mass the whole time I was photographing it. I assumed it was just looking for a good place to poke its ovipositor through the hardened froth, but maybe it was "patrolling"?
