Gerridae sp.
Backswimmers are predators and attack prey as large as tadpoles and small fish, and can inflict a painful "bite" on a human being (actually, similar to a mosquito "bite", it is a stab with their tubular mouthpart).
They inhabit still freshwater, e.g. lakes, pools, marshes, and are sometimes found in garden ponds. Although primarily aquatic, they can fly well and so can disperse easily to new habitat.
Photo 2 shows the disturbance to the waters surface when the water bug propels itself forwards.
