Abstract

Two forms of Hybomitra typhus (Whitney) flying together have been collected from Ontario bogs. The two forms have been clearly segregated by size and colour characters and also by differences in the appearance of esterase isozymes shown by electrophoresis. The combined data indicate that insects recorded as H. typhus comprise more than one species.
