There are at least 240,000 species of flies, the internets tell me, albeit less than half have been properly described. Some varieties are vilified as demonic disease bearing despoilers of all that is clean and good. This one is, as far as I know, an innocent fly, resting its stylishly grey on grey self on a matching bit of garden furniture. But it could be a villain. If I but had the will I might explore this site to it’s bitter buzzy depths.
Technically, f5.6 1/250 sec, ISO 320, focal length 50mm + a 16mm extension tube, whatever that adds up to. Vintage manual lens Super-Takumar on Sony A6000.
