Chauliodinae
Fishflies
Fishflies (subfamily Chauliodinae) are large, winged insects in the megalopteran family Corydalidae. Adults are distinguished from their close relatives, dobsonflies, by their relatively unremarkable mandibles and feathery antennae in males. Larvae are aquatic predators that inhabit clean, flowing streams, where they prey on other aquatic insects and small vertebrates. The subfamily contains approximately 15 genera and nearly 110 species distributed across North America, South America, Africa, Australia, and Asia.
