Spider Wasp - Episyron

Spider Wasp - Episyron
Cross Plains, Dane County, Wisconsin, USA
September 8, 2007
I was disappointed to not have gotten better photos of this wasp. It was continuously on the move around the goldenrod. Distinguishing marks were the two white marks on the mid-abdomen.

I'd say...
E. biguttatus based on the convergence of the eyes and having only one pair of spots is fairly typical coloration. However, the length of the tarsal comb spines remind me more of E. quinquenotatus, but that character is fairly variable and I can't see it well enough to count the spines.

Episyron
that tarsal comb is what made me not want to stick with biguttatus... gods know i have made enough mistakes though.

Yes...
they look too long and broad for E. biguttatus. It's probably safest just to leave it at genus level.

Episyron sp.
Looking at the photos it most resembles the Episyron biguttatus. Thanks.
