Xenoglossa strenua. People who know something about native bees often know about the "Squash Bee" Peponapis pruinosa. However, there are other native squash bees, and here is one. This is Xenoglossa strenua. It doesn't help that it looks mighty darn similar to Peponapis pruinosa...but both the male and females have yellow on the base of their mandibles, while P.p. does not. Helpful under the microscope at least. This specimen is one of the few, and the only recent, records for Maryland. Found in a sand mine in Anne Arundel County. An interesting note is that this species is not found in Maryland on any native plants, but only on the transplanted squash plants which originated in the Southwest and were migrated here eons ago by Indian farmers. Squash plants cannot overwinter in the region ~~~~~~~~~~{{{{{{0}}}}}}~~~~~~~~~~ All photographs are public domain, feel free to download and use as you wish.
