Eudasyphora cyanella
This record describes Eudasyphora cyanella (species). Recorded family: Muscidae. Recorded order: Diptera.
Identification and Appearance
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. 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. Sometimes overwinters indoors but often seen sunning itself outside on walls etc. 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. Common and widespread in England and Wales.

About Flies: the wider group
Order-level background for Diptera, the group containing Eudasyphora cyanella. Species-specific details appear above.
Group overview
Diptera includes over 150,000 described species of flies, mosquitoes, and midges. Mosquitoes are the deadliest animal on Earth (CDC). Malaria alone causes ~249 million cases and over 608,000 deaths annually, mostly children under 5 (WHO). Vector-borne diseases account for over 17% of all infectious diseases, causing 700,000+ deaths per year.
Ecological role of the group
Despite their disease impact, flies are critical decomposers and pollinators. Hoverflies alone pollinate hundreds of crop and wildflower species. Flies are also the primary food source for many birds, bats, and fish. Forensic entomology relies heavily on fly species for crime scene analysis.
Economic and practical significance of the group
In the U.S., vector-borne disease cases tripled between 2004-2016, with over 640,000 cases reported in that period (CDC). Tickborne diseases doubled from 22,000 to 48,000 annual reports. Globally, mosquito-borne diseases cost billions in healthcare and lost productivity.
Recorded sources for this group: WHO, CDC, PNAS. Imported estimates may describe particular regions or reporting periods.
