In that case I say it's a Southern Yellowjacket - Vespula squamosa.
But you know, you don't have to take it out on me. I didn't say anything....this time.

A point I was trying to make is that it would be more useful for editors to spend the time making keys to groups or expanding Info pages than to answering questions such as "how does one tell a female from a male" or "why was my image frassed"

Sam: your photography has improved greatly in a matter of a few weeks; thanks to your new camera and some on-line tutoring. But most of the credit must still go to you, well done.

I appreciate it. Although, I don't feel I deserve any credit....yet. The credit goes to expensive equipment and, as you said, advice and tutoring from people like you and Jay who took the time. It doesn't take a mental giant to buy high dollar equipment, follow instructions from pros, and then push a button. I feel that the deserved credit should come when I learn how to use my camera myself....really use it and understand all the settings, what they mean, and how to manipulate them. In the meantime though, hopefully I know just enough (to be dangerous) to get some pretty decent pics.

but your right, this is a female(worker) vespula squamosa

another hint: only one species in Oklahoma has those two lines on the thorax...
