Erythrodiplax (Libellulidae) (Dragonlets) of Michigan - Identification

This group of small to medium-sized dragonflies are principally Neotropical, with several species extending further north and one species, Erythrodiplax umbrata (Linnaeus, 1758), having been recently collected in southeastern Michigan (Craves and O'Brien 2007), representing a northward extension of its range in Ohio.

Nymphs are often found in lakes and ponds with aquatic vegetation...Life cycle information on Erythrodiplax is limited, but is probably univoltine in our area but, but for other species further south may be bivoltine (Kelts 1979).
