Phantom crane fly

Bittacomorpha clavipes

The phantom crane fly is a thin black fly with very long legs that have white bands near the tips. It drifts slowly through the plants, carried by the wind, with its legs spread out wide. When it floats past, the black parts seem to vanish and only the white spots flicker, like a little ghost.

Eastern North America, in shady, wet places at the edges of swamps and ponds
