Tiny Eggs

Tiny Eggs
Eugene, Lane County, Oregon, USA
October 8, 2020
Size: ~0.7mm
I recognize this is a very poor quality photo, but I thought it should still be documented with the others. I looked in the container today and found these tiny bugs that I believe to be parasitic wasps which emerged from some of the eggs.

I thought they were dirt at first, so I wasn't ready when I opened the container, and this is all I could get. Even with a lens for my phone, I could barely see anything. They definitely have clear wings and definitely fly, but beyond that I have nothing.

Edit, Oct 9: It kinda looks like it belongs to the genus Trichogramma. I have a couple more pictures that are slightly higher quality, but they aren't great. I'll replace them soon.

Edit, Oct 10: I changed the picture and added a couple more. I believe all of them hatched, and I let them go outside, which is when I got this picture.

Moved from ID Request.

It may very well be ...
... a member of the family Trichogrammatidae (which includes many genera, not just Trichogramma), but there are other families that attack eggs as well, and frankly, I can't tell from your image which these are. Maybe a better image will allow a family ID.

Better quality image
I changed the image and added a couple more. This is the absolute best I can do with just a phone and a clip on macro lens.

With the new images ...
... I am inclined to agree with you that this is a member of the Trichogrammatidae. Still can't give you a genus ID however.

What if I find out the host egg?
I'm raising a caterpillar of Heliothis virescens (Tobacco Budworm) that I found at the park on Symphyotrichum novae-angliae (Purple Aster), and have similarly raised some in the past from my back yard on Aquilegia canadensis (Red Columbine). These moths have several generations, and the last one happens to be in October/November.

It just occurred to me that such a moth is also a noctuid. Reading up on them, they appear to lay several hundred eggs that are ~0.5mm. These eggs are commonly parasitized by Trichogramma spp., particularly Trichogramma pretiosum Riley.

Ignoring species level identification, would it be acceptable to assume these are Trichogramma sp. if I were to raise one of the eggs into an adult moth that turns out to be Heliothis virescens?
