In the western US there are dozens, if not hundreds, of Fairy Bee species, many of which are flower specialists. So far only two species have been found in Vermont - a common Goldenrod specialist and a rare Ground-cherry (Genus Physalis) specialist.
Genus level ID – These tiny bees have a uniquely flat body with sparse, spine-like hairs. The Eight-spotted Fairy Bee has, well, 8 distinct yellow spots on the abdomen, while the Ground-cherry Fairy Bee is all black (female) or with indistinct spots (male).
