On the North Downs yesterday, I spotted this extraordinary looking insect. At first I thought it was some sort of beetle but the wings looked more like fly wings, but with small wings like that, it surely couldn't fly! On closer inspection, I realised what it was, and took a side view photo to confirm my suspicions. Just for fun, I wonder if anyone can see what is going on. The clue can be found by looking closely at the eyes. I will post the side view after I have had some answers.
Either a mutated fly, with two pairs of wings (flies should only have one pair) or, more likely, a mating pair of flies. I think I can see two sets of antennae. I don't know what species it is - I had a quick look through the tephritids on diptera.info but couldn't a good match. Nice photo.
Wow what a brilliant shot!! It is most certainly a mating pair of Snail-killing Flies (Coremacera marginata), they are really lovely lookers and have a beetle like appearance. They will also drop from leaves if disturbed like beetles, rather than fly away. The larva are quite adept at killing snails, hence the common name.
Do I win a prize?? : )
You win my admiration! I think it's spot on. Here is a photo I've found easily with the name you provided (Coremacera marginata). It's the two insects mating, but from an angle where both are visible, thus explaining the mystery you solved.
