Bittacomorpha clavipes
Eastern Phantom Crane Fly, Phantom Crane Fly
Bittacomorpha clavipes, the eastern phantom crane fly, is a distinctive fly in the family Ptychopteridae. Adults are small-bodied with exceptionally long, delicate black legs marked with white sheaths near the tips. The species is known for its unique flight behavior, using wind currents rather than wing beats for transportation, with legs spread to create air resistance. It inhabits shaded, moist environments near wetlands across eastern North America.
