Trichogrammatidae
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."

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.

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