Species Information


Description

The face is red and the thorax brown-red with two white spots low on each side (the remnants of pale stripes in immatures). The wing bases are orange streaked with dark brown. The legs are red-brown. Male’s broad abdomen is brilliant red; female’s is duller. Hamule shown in figure; vulvar lamina spout-like. Length: ♂ 38 mm, ♀ 37 mm.


Flight Period

B.C., mid May to mid October (mostly in June and July, which is early for a meadowhawk).

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

A common and striking resident of lowland coastal ponds and lakes. Males are easy to approach; they return again and again to a favourite twig over the water, perching with wings cocked downward, scarlet abdomen glowing in the sun. Female lays her eggs in tandem with male.

Distribution


Montane, as far south as Argentina and Chile. Lowlands of B.C.’s south coast to about 50°N.
