life history
Females overwinter in hollow sheltered areas as mated nullipars. They emerge very early in spring to take a blood-meal. Eggs are laid in rafts on semipermanent water bodies. Larvae tend to be found at the edges of ponds. Despite being a fairly common species, larvae are collected infrequently. Males have been recorded forming mating swarms. There is only one generation per year.

Common in Alberta.
