Bombus atratus is a neotropical bumblebee that is found throughout regions of South America, including Colombia, Ecuador, Brazil, and Argentina. It lives in social colonies that include a founder queen/queens, workers and brood. B. atratus is somewhat unique because of its potential to oscillate between polygynous (multiple queens) and monogynous (one queen) nesting cycles. Bombus atratus was the first species in the genus Bombus that was discovered to display such polygynous nesting patterns. The polygynous nesting cycles lead to certain specific types of behavior including queen-queen aggression. Nests can also be perennial, which is a characteristic rarely found in other bumblebees. B. atratus can be helpful agriculturally because of their ability to pollinate different species of plants.B. atratus has been found to occupy a range of geographic areas and climates throughout South America. Colonies have the ability to thermoregulate nests and keep them a little bit warmer than the outside environment. Foraging workers use muscle contractions to maintain stable temperatures and coupe with seasonal and daily fluctuations in temperature. Bombus ashtoni is a species of cuckoo bumblebee. This means that it parasitizes closely related species such as Bombus affinis, Bombus terricola, and Bombus fervidus by residing in the nests of these bumblebees and tricking the bees into providing resources such as food for them
Ashton Cuckoo Bumble Bee (Bombus ashtoni) is an obligate social parasite of B. terricola and B. affinis exclusively. The female invades her host’s nest, and if successful, is able to monopolize the existing reproductive biology of the host. This once widespread and fairly common cuckoo bumble bee has become rare in the lower U.S. since the 1990s. NatureServe (2013) reported that populations declined by up to 99% since the late 1990s. Colla et al. (2012) compared 50km2 blocks from across its range that were occupied anytime from 1864-1990 with data from 1990-2009 and found that the species only persisted in fewer than 35% of the blocks. Previously, B. ashtoni appears to have been a rare, but widespread, member of the Vermont bee fauna. Regional data and modeling suggest that it was probably found throughout the entire state. The last known B. ashtoni records for Vermont were three males collected in July 1999 at the Ethan Allen Firing Range in Jericho. Recent severe population declines of B. affinis and B. terricola have likely caused the parallel reduction in B. ashtoni populations. One host, B. terricola, became very rare in Vermont in the late 1990s and has only recently begun to show signs of a modest population rebound (VCE unpub. data). The second host, B. affinis, was last found in Vermont in 1999. Recent records from New Hampshire and Quebec provide hope that B. ashtoni may reappear in Vermont if B. terricola continues to persist and recover in the region.
