The tricolored bumblebee (B. ternarius) has a wide range of places that it lives.  This bee can be throughout the northern half of the United States and into parts of Canada (Johnson 2011).  It has been sighted all across the country from Yukon Territory to Nova Scotia, and while the climate is still livable for these insects farther south, they are rare to see south of Pennsylvania.  Bombusternariusis a seasonal insect making small nests of under 200 individuals each spring and all but the queens dying off at the end of the season (O’Toole 2002).  Their nests are seasonal as well, with the queens choosing a new location each time a new colony is to be formed.  These nests are typically underground and built in northern, temperate climates where the bees are most successful (Johnson 2011). These nests, however, are sometimes home to another type of bee.  The cuckoo bee will invade the nest and transplant its own eggs to be raised by the bees that live there.  The cuckoo bee is known as kleptoparasitic because it also steals food and lives off the success of the other nest.
