Physical Characteristics

Adults have reduced wing venation, including a lack of an anal cell and absence of crossveins h and bm-cu; cells bm and dm are confluent and end in the basal third of the wing.

Identification Tips

Identification is primarily based on the wing venation characteristics distinctive to adults of Hemerodromia, particularly the confluent cells bm and dm and the absence of certain crossveins.

Habitat

Larvae are aquatic and often found in riparian environments; adults are typically collected from riparian vegetation or using Malaise traps.

Distribution

Primarily found in the Nearctic Region, with a presence in parts of North America.

Diet

Larvae are reported to prey on black fly larvae.

Life Cycle

Life cycle includes aquatic larvae and pupae stages; adults are collected commonly in outdoor environments.

Ecosystem Role

Larvae serve as predators of black fly larvae, contributing to the aquatic ecosystem's dynamics.

Collecting Methods

• Sweeping from riparian vegetation
• Malaise traps
