Marsh Fly

Description:

~1 cm long, striped eyes and thorax, elevated leg stance, posteriorly facing wings

Habitat:

in grassy meadow with goldenrod

Notes:

Behavior is of an active, diurnal, visual predator, it stalks around along plant stems and is very visually aware of the photographer, can fly from stem to stem and then starts a meticulous "stalking" of the plant stem and leaves and moves on again. I wonder what it eats? The larva are supposed to be predaceous.
