Observed: 27th March 2012 By: AmadanAmadan’s reputation in InvertebratesAmadan’s reputation in InvertebratesAmadan’s reputation in InvertebratesAmadan’s reputation in Invertebrates

Quite numerous in mixed scrub of alder, beech, larch and ash. I don't know if identification will be possible from this shot.

Species interactions

No interactions present.

They are very shiny as far is i can remember. I have old photos from last year. Perhaps i had better have a dig for them...

Found it!

It was older than last year but that did not stop me locating the observation i never put on.
I was testing the camera and just took a few wide angle images of the swarm and never did any close ups. I was just curious as to why they were all in one place.

Thanks -

to both for the identifications. I'm no expert, and both seem reasonable. Hopefully there will be a few "votes" from others to help decide.

Green bottle / greenbottle is the common name that covers quite a few different species in various genera and families that all look green and shiny. The best known are Lucilia spp. - family Calliphoridae. The ones posted here are definitely not Gymnochaeta/Gymocheta which are bristly parasite flies (Tachinidae) and have quite a distinctive appearance when you know them. I'm no great expert on flies but had some shots I took of flies that seem a perfect match for the ones posted here and was given the reasons for the ID coming out as family Muscidae (by the wing veins) and as species Eudasyphora cyanella on a specialist fly site:
