Aquarius or Gerris?

The two genera are almost always able to be separated on the basis of size: 14 mm or longer, it's almost certainly Aquarius. You can also check the proportions of the antennal segments (A1>A2+A3, then Aquarius), but I can't quite make it out on the photo. They're tricky things to get a clear picture of, I know...

It seemed smaller than some

It seemed smaller than some I've seen, less than 14mm I would guess!
