Cuckoo Wasp

Hi Timothy,
We wanted Eric Eaton to concisely clarify the difference between Cuckoo Wasps and Sweat Bees. Here is what he wrote: “Well, actually, this is a cuckoo wasp (Chrysididae). It IS hard to tell the difference:-) You might note how the abdominal segments are unequal in length in many of the chrysidids, and the sculpturing on the thorax is generally much more coarse than it is in metallic sweat bees. Further, you don’t often see chrysidids on flowers. The are more often around aphid colonies, and old barns and such. Hope that helps a little. Eric”
