The gerris

Some strange creatures are moving jerkily over the surface of the water: Gerrises, insects related to bedbugs. Like a true insect, they have six legs and they «skate» across the water using their intermediate and hind legs which are covered in hairs to make them water-resistant. They are carnivorous and anything on the water surface, dead or alive, is good to eat! They catch their prey with the forelegs, sucking up the juices with their strong proboscis!
