Flight season: mid-June to late September.
Population: common, the largest numbers occur at the north shore of Stoco Lake,
but may be encountered at other marshes or ponds.
Sometimes found foraging a fair distance from water.
Length: about 30 mm to 35 mm. Usually – but not always – darker in appearance than the Familiar, Marsh and Hagen's Bluets.
However, these damselflies, particularly the females, cannot be reliably separated by sight
and the only way to be certain as to species is by study of the male's cerci and female's mesostigmal plates.
