Anthomyia pluvialis

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 . Male pluvialis can be distinguished by the dark mark at the base of the wings being divided into two separate spots. In males of procellaris and imbrida this is fused into one connected spot. However, female imbrida have the supra alar spot disconnected from the dorsal lateral spot, like female pluvialis . However, the supra alar spot on imbrida extends to the lateral seta whereas it doesn't in female pluvialis . An image of the side view showing the two spots on the thorax is required. It is often seen on umbellifers and other flowers. It is thought to 'dance' before rain, hence its scientific name. It breeds on rotting vegetation. Fairly common and recorded across England and Wales. No additional images available for this species.
