PUPA OF BOMBUS IMPATIENS The pupa of B. impatiens corresponds in all respects with that of B. pennsylvanicus De Geer) (as B. americanorum (Fabricius)) and B. vosnesenskii Radoszkowski based on characters identified by Michener (1954). That is to say, there are no pupal features of the head or mesosoma except for the legs.
