tiny wasp - male

tiny wasp - Male
Cross Plains, Dane County, Wisconsin, USA
June 7, 2009
Size: .5mm
One of the tinier wasps I have least I think it's a wasp judging by the antennae.

Moved from parasitic Apocrita.

is where it should go. I have no thoughts about the genus.

Moved from Scelionidae.
Let us keep it here until we know for sure.

I received a note regarding this wasp from Danny O'Shea from Forest Pest Mgmt, NB Dept. of Natural Resources

"... but it does not look like one, especially those red eyes. I believe it is actually a chalcid, more specifically Trichogramma. T. minutum is a known parasitoid of Tortricid egg masses. If there are only 3 tarsomeres at the end of each leg, it is definitely Trichogrammatidae, not Scelionidae."


Fits this family including tiny size, lack of a wing stigma and very reduced venation, elongated oval abdomen that is dorsoventrally depressed, yellow or multicolored possible, and a sculptured thorax. These are diverse-looking egg parasitoids. Pectinate antennae may indicate a male.

See reference here.

Just wanted to add the comment that I saw some of these tiny wasps on Tortricid eggs earlier this summer.

So, when do you switch to a microscope?
That one is really miniscule!

Sometimes it's hard to tell them from plant debris except when they move.
