Velia caprai, known as the water cricket, is a species of aquatic bug found in Europe.

In one study, whenever the bug Velia caprai (Water cricket) took prey heavier than 7.9 g, other bugs of the same species joined it and successfully ate parts of the prey.

Nevertheless, the oxygen-scarce water still contained many forms of life: water-lice, tubifex worms and blood worms; mosquito larvae and rat-tailed maggots; pond skaters, water crickets and water beetles.
