Life cycles and food of coenagrion resolutum (coenagrionidae: odonata) and lestes disjunctus disjunctus (lestidae: Odonata) populations from the boreal forest of Alberta, Canada

In a boreal forest pond of Alberta, Canada, some Coenagrion resolutum were univoltine while others were semivoltine; all Lestes disjunctus disjunctus were univoltine. Life cycles and diet of nymphs (mainly Cladocera and Chironomidae) of both species were similar in the different vegetation zones.
