Eudasyphora cyanella

This shiny green fly gradually become bronze as it ages. As with all muscidae flies, the fourth wing vein (M) bends gently (not sharply) forwards. It has hairy eyes and a white 'collar' on the front of the thorax.

Similar Species

Superficially this looks like the 'greenbottle', Lucilia, which is in the Calliphoridae family (blowflies) which have a sharp kink in wing vein M. Also Eudasyphora has a dark stripes extending backwards from the pale front of the thorax and Lucilia doesn't have this.
