Identification
Distinguished from other large crane flies by combination of size, testaceous coloration, and geographic distribution in eastern North America. Separation from requires examination of genitalic structures and wing venation patterns. The long, fragile legs and V-shaped between the thoracic segments help distinguish Tipulidae from other .
Habitat
Associated with moist environments supporting larval development; often found near streams, wetlands, and wooded areas with decaying organic matter where larvae develop.
Distribution
Eastern United States: Maine southward through Tennessee to Florida.
Life Cycle
Complete (holometabolous). Larvae are aquatic or semi-aquatic, living in moist soil, decaying vegetation, or shallow water. are short-lived and do not feed, or feed only on nectar. Specific larval requirements for this are not documented.
Behavior
are weak, fluttering fliers most active during or periods. Adults are frequently attracted to artificial light sources.
Ecological Role
Larvae contribute to decomposition of organic matter in moist . serve as prey for spiders, birds, bats, and other .
Human Relevance
are sometimes mistaken for giant mosquitoes but are harmless and do not bite. No documented economic importance.
