About

There are nine species of pond skater in the UK, which range between 1-2cm in length. Often seen in large groups, they 'skate' around on the surface of the water in ponds, lakes, ditches and slow-flowing rivers, feeding on smaller insects which they stab with their sharp mouthparts or 'beaks'. The common pond skater emerges from hibernation in April and lays its eggs. Hatching soon after, the nymphs go through a number of moults.

How to identify

The brownish-black, long-legged common pond skater is only likely to be confused with the smaller, thinner, more fragile-looking common water-measurer, or the smaller, chunkier, shorter-legged water cricket.

Distribution

Widespread.

Did you know?

Common pond skaters have water-repellent hairs on the bottom of their feet, enabling them to walk on the surface film of the water. They hunt by detecting vibrations in this film.
