Colletes simulans

Colletes simulans, commonly known as the spine-shouldered cellophane bee, is a solitary bee species in the family Colletidae. It is found in North America and shares the characteristic behaviors of its genus: nesting in underground burrows lined with a cellophane-like secretion and provisioning cells with pollen and nectar for larval development. As with other Colletes species, it is among the early spring-emerging native pollinators.
