Smouldering summer like temperatures and weather have arrived after weeks of chilling North East winds. Our spring which always felt as cold as winter, has suddenly turned to summer - (for now)! Under mostly blue skies at the top of our Blackthorn trees, a small swarm of weak flying black flies (15 mm long) with shiny irridescent wings and long black antennae 40- 50 mm have danced, basked and displayed together. They have in fact slowly moved from tree to tree down the garden boundary with the paddock (following the sun). They remind me a little bit of the Solomon Seal Sawfly or St Marks fly, but then close observation shows them to be more like a Dancer fly. They are structurally different though and as yet I can't put a common name to them. Their attention has not gone unnoticed by others with big eyes around the garden to - see below!
The flies seem to dance around each other and also flick their wings in display too. But the warm sun has also brought a rush of adult Large Red Damsel flies to the garden and pond margins too - and as you can see a dancing delicate fly doesn't always just attract a mate!
