Ecology of Species of Bombus Latr. (Hymenoptera: Apidae) in Southern Alberta. I. Subgenus Alpinobombus Skor.
Abstract In southern Alberta the range of Bombus ( Alpinobombus ) balteatus was limited to mountainous areas with minimum elevations of 7,400 ft. When given equal opportunity to nest in above- or underground hives, queens established in two above, and 12 underground hives. The middle of the nest-est...

All eggs of the first brood were deposited in n single cell; not all were deposited on the same day. Second- and third-brood egg cells were built in parallel lines on each side of the incubation groove. At least once, the second brood was also workers. Succeeding broods were probably first males and then queens, as males emerged first. Pollen was fed collectively to worker larvae of all instars, except the last, by stuffing it beneath them.

Last-instar larvae of all broods separated from each other by spinning flimsy, incomplete cocoons, and were fed individually mixtures of honey and pollen.
