Bombus citrinus, U, side, Maryland, Caroline County
A parasite of other bumblebeeds, B. citrinus, is the most common parasitic species in the East, but, as a parasite this still means it is very uncommon. The tale is simple, this species invades a nest, eliminates queen, and makes workers raise its own young.
