Unequal cellophane bees (Colletes inaequalis) are common in early spring across eastern North America where they build nests underground in sandy soils. True harbingers of spring, they visit many early-blooming tree species such as red maple (Acer rubrum), serviceberry (Amelanchier spp.), redbud (Cercis canadensis), and pussy willow (Salix discolor).
