Black Petaltail (Tanypteryx hageni (Selys))
Behavior: Nymphs construct small burrows in water-logged substrates. Adults have been observed on feeding and mating flights over a cat-tail swale in Oregon. Males are territorial over bogs.
Food Habits: Nymphs eat surface-inhabiting arthropods, mostly spiders. Adult dragonflies prey on flying insects, while nymphs feed on aquatic animals. No specific information is available on the prey of this species.
Habitat: Waters seeps with moss-covered rocks. Occurs in spring-fed bogs or seeps in old growth or riparian forest.
Range: Southern British Columbia south to central California.
