Cryptocheilus attenuatum - Female

This is one of my favorite spider wasps found in Ohio. It's the only one with orange wings. They are fairly common on flowers in meadows in the east. Hopefully someone might be able to photograph a live one.

Yes!
Got these in Cincinnati, too, glad to have verification. Townes seems to show them only in the plains states as I recall.

 
Yeah...
...my theory is that Townes and Evans are such broad-based studies that they still left a lot of gaps in what we know about geographic distribution for spider wasps. I still have yet to send you a list, but probably 50% of the species would be new literature records. I was also surprised about the diversity in Ohio. Ohio has 99 species of spider wasps and a hypothetical list of 14 more. Hamilton County (is it Hamilton or nearby?) would also be a new county record for this wasp.

There ia a specimen in AR and also have MO TX listings.

 
Yeah...
there is another problem. I don't think Townes or Evans visited smaller collections during their revisions. They may have done determinations later, but that data is not presented to the public. I imagine C. attenuatum is probably pretty close to transcontinental.
