Colletes thoracicus
Rufous-backed Cellophane Bee, Rufous-chested Cellophane Bee
Colletes thoracicus, commonly known as the rufous-backed cellophane bee, is a solitary ground-nesting bee native to North America. It belongs to the family Colletidae, which are known as plasterer or cellophane bees due to their unique nesting behavior. Females construct individual burrows in sandy soils and line the interior chambers with a cellophane-like secretion produced by a gland in their abdomen, creating waterproof brood cells. This species emerges early in spring and is an important native pollinator of early-blooming plants.
