Coelioxys porterae, male, Maine, Acadia National Park
Another Coelioxys nest parasite bee from the Adirondack Mountains of New York. This one is a nest parasite of big Leaf Cutters like Megachile latimanus. Here are shots of a male and a female.

The most common of the Coelioxys nest parasites in the mid-atlantic region. This is C. sayi, in this case, a male and simply a mating machine, not involved in nest construction. Check out the multi-pointed rear end. I am unaware of what use this is, but most of the Coelioxys males have some variant of this unusual pattern. Photographed by Ashleigh Jaoobs.

The most common Coelioxys in the East. C. sayi is a nest parasite, slipping into the nests of leaf cutters like Megachile mendica and kin and dropping an egg into the wall of their nests. In the female, like this one, the edge of the clypeus is slightly indented (hard to see). Now you know.

This is the male of a species that parasitizes Megachile (leaf cutter nests) by laying their eggs in the nest of the host, after which the young Coelioxys sodalis emerges and kills the host larvae and consumes the pollen and nectar of the host's young. About 20% of all bees work on this model.
