I'm afraid I don't have a photo as it was while I was away, but I can describe it quite well.
Basically a gnat came into the hotel room (still in the uk), but as I looked closer it was in fact green, which I found weird. It also had 'hairy' antennae, similar to those some moths have. I've never seen a gnat/mosquito/etc look like this before so I thought I'd come ask what it was! Was also a similar size to a gnat, 8mm-1cm ish.
