Water stick insect

The water stick insect looks just like a mantis. An underwater predator, it uses its front legs to catch its prey. Its tail acts as a kind of 'snorkel', so it can breathe in the water. Look for it in ponds and lakes.

About

An underwater predator, and a relative of the water scorpion, the water stick Insect hides among reeds and stems in lakes and ponds. Here, it waits, perfectly camouflaged, ready to ambush its prey. It adopts a mantis-like pose when submerged, capturing passing creatures like tadpoles and small fish. Like the water scorpion, the water stick Insect uses its long, thin 'tail' as a siphon for breathing: it protrudes above the water's surface and acts just like a snorkel. Mating occurs in spring and the eggs are laid soon after on floating plants and stems. Nymphs go through a series of moults to reach adulthood.

How to identify

The water stick insect has a long, thin, brown body, and a long 'tail'. It resembles a mantis, with long, hooked front legs.
