Summary: | Abstract Two species of Apidae occur on Ellesmere Island: Megabombus ( Megabombus ) polaris (Curtis) and M . ( M .) hyperboreus (Schönherr). Some observations on their activity are presented. Three nests built on the surface of the ground are described. The colonies were of small size. Nest No. 1 contained only polaris Nests Nos. 2 and 3 contained polaris workers and hyperboreus sexuals, as adults or brood. Usurpation is suggested to explain the workerless condition of hyperboreus in Nests Nos. 2 and 3. |
