They vary in colour from copper-brown to grey. They are usually much smaller than any of our native snakes. Unlike snakes, they also have eyelids and can close their eyes. Slow-worms live in places with plenty of grassy cover and warm, sunny banks. They are secretive and difficult to find, Trust grassland reserves in the south of the county are probably the best place to look.
Common lizards are often confused with newts.
The habit of basking on walls, leaves and rocks is unique to lizards, and any small herptile doing this in Lincolnshire will be common lizard. They are found in almost all habitats and can be seen on most nature reserves, particularly those with grassy banks and bare areas. They are particularly approachable in April and May, after hibernation. The common frog is easily distinguished from the common toad by the smoothness and wetness of the skin, the variable colour, the dark patch behind the eye, and the fact that it hops instead of runs. There are other native and alien frog species, but none occur in Lincolnshire.
