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.

Identification difficulty

Sometimes overwinters indoors but often seen sunning itself outside on walls etc.

When to see it

Because this fly overwinters it is one of the first to appear each year, remaining with us from March through to October but most common in April and May.

Life History

Overwinters in adult stage.
