Species Information


Description

Similar to the Cardinal Meadowhawk, but the male’s abdomen is not as broad, the orange wing bases do not have dark streaks and the legs are black. Immatures are grey-brown; males and some females become red and, with age, darken to wine-red. The thorax sides have a pair of white stripes that reduce to spots on mature males. The wing veins are yellow, turning red with age; old ones have brown-tinted wing membranes. The sides of the abdomen bear a white stripe bordered above by black, but these marks fade with age. Hamule shown in figure; vulvar lamina a third the length of segment 9, its lobes short and triangular. Length: ♂ ♀ 39 mm.


Flight Period

B.C., late May to late September; Yukon, late June to mid August.

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

Uncommon. Develops in a variety of still-water habitats, including marshes, sedge fens and saline grassland ponds, which often dry up in summer. Females lay eggs in water or on the beds of dry pools.

Distribution


Western. Widespread in southern B.C. to about 53°N. Probably occurs in northern B.C., because there is one record in the southern Yukon.
