Another Native Cuckoo Bee
There are many types of cleptoparasitic (Cuckoo) native bees - bees that don't collect pollen and build nests, but instead lay their eggs in the nests of other bee species. The host species' larvae is usually killed leaving the bee bread (pollen and nectar ball) for the Cuckoo Bee to eat as it develops.
Cuckoo Bees will visit flowers for nectar only (no pollen collecting structures). I observed this Triepeolus sp. nectaring on Cup Plant and Hoary Vervain in mid-July.
