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 think I have one or two more somewhere waiting for me to examine them. I mostly encounter them during the daytime but this one came to light at night.
