Perplexing Bumble Bee Bombus perplexus Cresson, 1863  
Kingdom Animalia   >   Phylum Arthropoda   >   Class Insecta   >   Order Hymenoptera   >   Family Apidae   >   Genus Bombus   

Status:

In our area, its distribution largely stops at the Fall Line; few are recorded on the coastal plain (S. Droege, pers. comm.).

Description:

Note lemon yellow coloration. For some reason this species' coloration tends towards bright yellow while other eastern bumbles are more subdued in their yellowness. It varies with their age (the sun fade bumbles plumage) but a nice lemon yellow usually means this species. Males have 13 rather than 12 antennal segments and the hind legs lack the pollen-carrying corbicula (bare area) on the tibia. (S. Droege, pers. comm.)

There are 37 records in the project database.
