Water Scorpion Nepa cinerea

Water Scorpion Nepa cinerea (Linnaeus, 1758)
A large, slow moving and aggressive predator, the Water Scorpion is relatively common throughout Nottinghamshire. It frequently turns up in childrens nets during pond-dipping sessions held by schools. The Water Scorpion lies concealed in weed or leaves on the base of the pond and waits for passing prey, taking other invertebrates, small fish and tadpoles.
