This genus is the Dalmatian of the fly world, with a striking chequered appearance. The background is usually grey but can be brown with distinct black spots.
Anthomyia pluvialis is very similar to A. imbrida and A. procellaris. Pluvialis can be distinguished by the dark mark at the base of the wings being divided into two separate spots. In procellaris and imbrida this is fused into one connected spot.
An image of the side view showing the two spots on the thorax is required.
It is often seen on umbellifers and other flowers.
Summer and Autumn.
It is thought to 'dance' before rain, hence its scientific name. It breeds on rotting vegetation.
Fairly common and recorded across England and Wales.
Uncommon or under-recorded in Leicestershire and Rutland.
