Enlargement looks like a damselfly, the original with the deer in the background looks like a mosquito I wouldn't want to tangle with.
If water was nearby many flying insect hatches (read: trout food) hatch during the night, I have living proof from my own nearby small stream
and game cam footage to prove it. Bottom line: very reflective insect with more than two legs as you might expect. Don't let Biscardi get wind of
it though or the beavers will have wings.
