  • The back is usually a shade of grey or brown and the belly is pale orange or yellow.
  • Small black dots cover the belly (including the throat); there may be dark spots or stripes along the back. During the breeding season males develop a continuous wavy crest down the spine.

Smooth newts look very similar to palmate newts but are more widespread; they’re found throughout Britain and Ireland. Smooth newts can not tolerate as dry conditions as palmate newts. On land, their skin takes on a velvety appearance and they are sometimes mistaken for lizards. Like common frogs they are usually quite quick colonise garden ponds.

A year in the life...  

Spring Adult newts emerge from their overwintering sites in early spring and head to a pond to breed. Males perform an elaborate courtship dance before the eggs are laid. Individual eggs are laid and wrapped up in the leaves of pond plants. Depending on local weather conditions, two to four weeks later larvae (sometimes called newt tadpoles) will hatch out. The larvae have feathery gills around the head, distinguishing them from frog and toad tadpoles. A couple of months after they hatch the larvae start to grow their front legs (again, different from frogs and toads), followed by the back legs. At this time of year adult newts spend quite a lot of time in the water and will hunt frog tadpoles.
Summer When the larvae have absorbed their gills, they leave the water as newtlets (or efts). Adults may still be in or around ponds hunting for food.
Autumn Later in the summer and in autumn, newts can be found sheltering under wood, rocks and paving slabs, in between feeding up on slugs and insects in time for winter.
Winter Smooth newts spend the winter sheltering under rocks, in compost heaps or buried down in mud; occasionally they will overwinter in ponds. They don’t hibernate as such, and may take advantage of milder patches of weather to come out and forage.
