Green-eyed Wasp (Tachytes sp.)

This summer I finally got to spend a little quality time wandering through Sand Prairie Conservation Area in Scott County, MO. Within and bordering the dunes one walks by large numbers of Stylisma pickeringii (Convolvulaceae) and Polygonum americanum (Polygonaceae), the later called American jointweed. If you arrive at or near sunrise there does not seem to be a lot of interest in regards to pollinators. Wait until the day heats up, say around 9 or 10 am, and then things get hopping. I saw all sorts of insects I had never seen before, mostly in the Hymenoptera. One of these was the green-eyed wasp (Tachytes sp.). Of course, when everything is warmed up, getting the photographs you want of these small and active insects becomes an epic story of frustration. But, try and try again and you might get something you’re happy with. The following pics aren’t as nice as I had hoped but I think they show this splendid little wasp as you might find them in situ.

With a head that is almost all eyes, the green-eyed wasp (Tachytes sp.) is always wary and alert to potential threats.
