Aphid Wasp - Stigmus

Aphid Wasp - Stigmus
Duck Lake, Glacier County, Montana, USA
July 23, 2006
Size: under 10 mm
Looks similar to Diodontus minutus from one of my books. This one just finished eating an aphid.

Moved from Stigmini.

Moved from Aphid Wasps.

Those are tiny wasps! Great shot, Lynette. May I ask Dr. Ascher to please fill out his biography page a little? We can use some more knowledgeable hymenopterists here!

note large stigma

Pemphredonine Wasp (subfamily Pemphredoninae)
Despite very similar habitus, this one little wasp has a second closed submarginal cell on forewings (a Crabronine would lack it). Moreover, Crabronine Wasps have a special face with VERY broad, squarish compound eyes.
