Andrenid bees are a type of native ground-nesting bee that is first seen during early spring. Residents are discovering them now in their gardens and lawns. Some people have been concerned that these insects may be ground dwelling yellowjackets (wasps) but the overwintering queens are only just starting to build new nests and people would not be seeing any activity from their nests this early.

These native bees are very important pollinators and should be tolerated. They are active for several weeks, and then complete their life cycle. They are gone on their own by May so they are only present during spring.
