Marsh Snipe Fly

Rhagio tringarius can reach a length of 8–14 millimetres (0.31–0.55 in). The abdomen and the long slender legs are yellow-orange. The patterning on the abdomen is quite variable, but usually it shows black well spaced dorsal triangles. Also the last abdomen tergites are black. Wings are clear, as this fly lacks the dark wing stigma common in the genus Rhagio.

This species is present in most European countries, as well as part of the American Northeast and the upper half of the west coast. It can be found in wet meadows, hedgerows, woods and areas with a rich vegetation.

The larvae of this snipefly dwell in the ground, on litter and detritus. They are predatory hunters, feeding on small beetles and earthworms. Adults occur from May to September, usually resting on leaves.
