Species Information


Description

Thorax is dark brown or black with narrow pale stripes; the pale underside has several (usually three) dark spots on each side. Length: ♂ ♀ 40 mm.


Flight Period

B.C., early June to mid November (flight before early July is unusual).

Genus Description


Large damselflies, brown, black, metallic-green or bronze above, mostly pale below. As they age, parts of the body, including the tip of the abdomen in males, often become pruinose bluish white. Females lay eggs in tandem with males, usually in plants above the surface of the water. The larvae are long and slender with banded gills and an unusually elongated labium. Some species are adapted to temporary ponds; the eggs overwinter and the larvae grow rapidly after the basin fills with water in the winter or spring.

Biology

Family Description

A small but widely distributed family in B.C., containing only one genus here, Lestes, with five species. The common name comes from the characteristic posture of the adults - they usually perch with wings half-spread.
Field Notes

Common in many types of wetlands, from alkaline ponds to cattail marshes, lake and peatlands. In B.C., it emerges later than any other spreadwings and is the last damselfly seen in autumn.

Distribution


Widespread. And widespread in B.C., especially in the south.
