Sapygidae (Parasitic wasps)



Sapygidae is a small family of wasps that parasitizes Megachilidae bees. The Sapygid wasps are relatively rare, and not well studied (Kurzenko (1996). There are 18 species recorded in North America, North of Mexico (Kurzenko, 1996).


These are yellow and black wasps of small-medium size, similar superficially to some of the Eumenid wasps we get. However they have smoother exoskeletons and flatter abdomens then Eumenids.

Nest Structure

In Bee Atlas blocks these wasps parasitize Osmia tersula and Osmia pumila.
