Notch-horned Cleg Haematopota pluvialis
Haemotopota clegs are a common species at the site where this was taken, and can be a painful nuisance. This appears to be the first I've identified to species level, though I may have another somewhere waiting for me to examine it. I mostly encounter them during the daytime but this one came to light at night.

My attempt to catch this one failed so all I have to go on is these two photos. It was at the same place as the one above and I think you can see enough detail on the antennae to confirm it's another pluvialis.
