Species Information


Description

Distinguishable from others by the wide band of yellow or brown on the basal half of the wings. The yellowish face darkens to brown with age; the yellow-to-brown thorax has dark lines, thickest around the leg bases; the legs are black. The abdomen has black side stripes against brown on immatures, red on mature males and either colour on mature females. Hamule shown in figure; vulvar lamina a short, shallow trough. Length: ♂ 36 mm, ♀ 34 mm.


Flight Period

B.C., mid June to mid October.

Genus Description


Small to medium-sized dragonflies that are mostly yellow when young and mostly red when mature; one common species is black. Females are usually yellow or tan, but can be red like males. You can watch most species easily at close range, because the adults are not powerful flyers and perch often. They are frequently abundant around ponds and lakes and adjacent meadows, especially in the late summer and fall. Many species will perch on the ground; Sympetrum means “with (or on) the rocks”. Species can be difficult to distinguish. Look for the colour of the face, legs and wing veins; the patterns on the sides of the thorax and abdomen; and the details of the genitalia (the male’s hamules and the female’s vulvar lamina).

Biology

Family Description

The largest dragonfly family in our region – 24 species in eight genera live here and one other species in another genus is a rare visitor. They come in many sizes and colours, many with bold wing markings or coloured veins. Their eyes meet broadly on top of the head. The anal loop in the hindwing is distinctive: foot-shaped with a long toe. Most common around ponds, marshy lakeshores and sluggish streams, the adults dart about and most species spend a lot of time perched horizontally in the sun. Females lay eggs alone or in the company of guarding males. Most dip the tip of their abdomen into the water when releasing the eggs, but some will tap or splash the eggs into wet mud or moss, or simply flick them into a dry pond basin. Some larvae, like those of the emeralds, move sluggishly or squat on the bottom mud; others climb in vegetation.
Field Notes

Not as common as some of its relatives, but lives in a variety of ponds, marshes and lakes, especially shallow, grassy or reedy places. Foragers and mating pairs often wander well away from water in open country. Some experts consider it a subspecies of the eastern Band-winged Meadowhawk (S. semicinctum).

Distribution


Western. Widespread in B.C. south of 52°N.
