Say's Cuckoo-leaf-cutter Coelioxys sayi Robertson, 1897  

Status:

"The most common Coelioxys in the East. This is C. sayi. Now, C. sayi is a nest parasite (like all Coelioxys) and it likes to drop its eggs in the nest of what is usually the most common leaf cutter in the East, Megachile mendica. That said, these bees are so little studied that it would not be at all surprising to find that it also is dropping eggs in similar hosts such as M. brevis. These bees are well-armored against the stings of the hunky leaf cutters, to the extent that putting a pin through them when preparing them can be a bit crunchy. (Another cocktail fact from your favorite government program)." (S. Droege, pers. comm.)

A female Coexlioxys sayi in Howard Co., Maryland (8/4/2013). Notes from Richard Orr: "This female Leafcutting Bee (Coelioxys sayi) is a parasite of other Leafcutting Bees in the genus Megachile. They are far less common than their hosts so they are always a pleasure to find. The added bonus was that this was a new county record and only the second species of Coelioxys to be recorded in Howard County, Maryland." Photo by Richard Orr. (MBP list)
