Pond skater Gerris lacustris

Found on ponds, marshes, streams and slow-moving waters, the pond skater is a small, thin black-brown insect. They have small heads and relatively large eyes. Pond skaters use their long thin legs to propel their body across the water. The middle legs are used to propel the insect’s body forward and the back legs are used for steering. The pond skaters’ sharp mouth parts and their smallest set of limbs are used to prey on small insects found on the surface of waters.

Behaviour

The pond skater gets its name from their method of hunting smaller insects by gliding on the surface of the water. Over winter they hibernate on land, emerging the next spring to either return to the same pond or to colonise a new waterway.
