Waisted Duckfly

Anasimyia contracta


Wing length 5 - 7.5mm. An unusually marked hoverfly with a black abdomen, with white, club-shaped markings, and a dark brown thorax with buff, longitudinal stripes.


Bogs, ditches and pond edges where there are plenty of emergent plants, particularly Typhus. The larvae develop in the leaf sheaths, often below the water.

Status and distribution

Fairly common in England and Wales but much less common in Scotland, and absent from the north. Fairly common on the reserve.
