AR Bumble Bees


Working list of the Bumble Bees likely in Arkansas. We likely have about eight species in the state (red species). List obtained from internet sources and now frm Bumblebees of North America, Williams, Thorp, Richardson & Colla. Groups from that book listed for AR species. This list below does not include the Cuckoo bumblebees and we likely have five or six of those in the east as well. Arkansas will only have the cuckoo Bombus variabilis and it only parasitizes B. pensylvanicus.

 

Ranges are from now from B of NA maps. Of the 46 North American species there are likely 20 or so eastern species and only 7 occur in Florida as they tend to favor cooler climates with their excellent temperature regulation capabilities. Six of those are Cuckoo bumbles. Several species occur only in the high Arctic and Alaska, several are California only. Images of confirmed species on the internet are not common. Links for photos are available on all of these species. Note the workers, queens and males can have very different color profiles. These links are from the excellent Pickering site. (Note the second form of B. rufocinctus is linked to the descriptor).
