An average painted turtle is ﬁve to seven inches long. Its smooth shell has a red, yellow and black color pattern. The female is larger than the male. An adult male has very long claws on its front feet. This turtle has yellow stripes on its head and dark coloring on the plastron (lower shell). The carapace (top shell) of the hatchling is keeled (has a ridge).
The painted turtle may be found statewide in Illinois. It lives in shallow water bodies with many aquatic plants and a muddy bottom. Typical locations include ponds, marshes, ditches, lakes, streams and river pools. Although aquatic, the painted turtle is frequently found on land. It is often seen sunning on a log at the water’s edge. It is active during the day. The mating season lasts from April to June. The male courts the female in a ritual involving stroking her head with the back of the long claws on his front feet. The female in turn strokes his front legs with her claws. After mating, the female digs a nest in soil a few feet from the edge of the water. Eight or nine eggs are deposited in the nest during the middle of the day. More than one clutch of eggs may be deposited by the female during the year. Hatchlings may be found after two to two and one-half months but usually overwinter in the nest. The painted turtle eats plants, insects, crayﬁsh, mollusks (snails, slugs and others), ﬁshes (live and dead) and amphibians.
