Velia caprai, known as the water cricket, is a species of aquatic bug found in Europe. It grows to a length of 8.5 mm (0.33 in) and is stouter than pond skaters of the family Gerridae. It is distasteful to predatory fish, engages in kleptoparasitism, and can travel at twice its normal speed by spitting on the water surface.

DescriptionEdit

The adult insect grows to a length of 6.2–8.5 millimetres (0.24–0.33 in).[1] Members of the family Veliidae resemble the pond skaters of the family Gerridae, but with stouter middle and hind legs, and a generally stouter appearance.

EcologyEdit

Velia caprai has a chemical defense mechanism which is often able to prevent predation. It is so distasteful to brown trout (Salmo trutta) that the fish will spit out any Velia caprai it takes without causing them any damage.
