Recognition
Resemble large crane flies (Diptera: Tipulidae), but have four wings (not two) and no halteres. Hang by front and middle legs from low plants, and use hind legs to capture passing prey. Tarsi have only one claw. Like Scorpionflies, have a prominent 'beak' but wings are unspotted, at least in NA species.

BIOLOGY
Males offer nuptial gifts of prey to females. They mate while hanging from a perch.(2) Eggs are rectangular, with a depression on each side. They are laid on marshy ground during summer, and hatch the next spring. Larvae resemble caterpillars and are unique among the larvae of holometabolous insects in that they have ocelli.
Food
Predatory on small insects, especially Diptera. Capture prey with hind legs while hanging by front legs from perch.
Habitat
Typically woodlands near streams; adults often attracted to lights
Diversity
10 Species in 4 genera in America north of Mexico.
