Tiny wingless wasp? - Trimorus - female

Tiny wingless wasp? - Trimorus - Female
Windham, Rockingham County, New Hampshire, USA
December 2, 2006
Size: about 1.1 mm
I see what appear to me to be vestigial wing buds along the sides.

The width of the numeral 3 on this watercolor brush handle is exactly 1mm.

Vestigial forewing buds, yes...
They tend to prove that, in the case of this one female at least, this extreme brachyptery - hence flightlessness - is inborn. But the thorax is by no way modified externally, and both normally winged and wingless individuals of exactly same size, color, etc., can often be found together.
