Eastern Sphecid Related Wasps

 

Working list of the possible Eastern Sphecid wasps with new families, subfamilies, tribes and subtribes noted. (See this paper from the wasp man, Pulawski, with some reordering of the family groups. I am working on shuffling the list around based on this update.)

 

Otherwise taken from combined sources including the internet and the impressive but slightly outdated Sphecid Wasps of the World from Bohart and Menke. Ranges are spotty with states and regions listed for known occurrences. These are now updated to literature references from the Catalog update mentioned below. I have no lists of confirmed Arkansas species as of yet. Species with AR in blue with a numeral are in the collection at UA Fayetteville and have the number of counties represented by the numeral. Species will be removed from the list when I have information narrowing the ranges outside of the east. "Nea" refers to number of species listed for all of North America at the excellent Nearctica insect list.

 

And here is the updated Sphecid Wasp Catalog from the California Academy of Sciences (covers the entire globe but it is more UTD). Presently there are about 1400 species in North America. Habits and identifying characteristics given where known. Prey choice of species and groups marked in red where known from various sources.
