Lestes congener is a species of dragonfly from the genus of the rush damsel ( Lestes ) that is widespread in North America.
features
Male Lestes congener reach a body length of 35 to 42 millimeters, the females remain somewhat smaller with 32 to 38 millimeters. In the western part of their range, however, the dragonflies become somewhat larger than in the eastern part. The body of the males is bronze to black with yellowish spots, the last two segments of the abdomen are gray. The females are a little paler and the abdomen is reddish brown. The wings are clear and transparent and longer in the females than in the males.
The larvae are up to 25 millimeters long and light brown.
distribution and habitat
The distribution area of Lestes congener is in North America in the United States and Canada . It extends from southern Ontario and New Jersey west to California and north to British Columbia . They live mainly on the banks of permanently or temporarily water-filled ponds and flooded river banks.
Way of life
The adult dragonflies feed on small flying insects such as aphids . The larvae hunt small underwater insects and their larvae. In autumn, the females pierce their eggs individually in plant stems above the water level or in autumn leaves and other plant remains. The eggs are resistant to both drought and frost. The larvae hatch when the plants fall over in winter and come into contact with water. The flight time of the Imagines ranges from late July to mid-September.
Systematics
Lestes congener is one of 83 species of rush damsel ( Lestes ) known today. They were scientifically described for the first time by the German-American entomologist Hermann August Hagen in 1861.
