Amphibians & Reptiles
It is not uncommon to find some species of amphibians (frogs, toads, salamanders) and reptiles (snakes, lizards, turtles) in residential yards and around buildings in Illinois. These animals may live in or around a building for several months, or they may be seen briefly as they pass through an area on the way to a breeding or hibernation site. Most species present no danger to humans or pets. In fact, it is more likely that amphibians and reptiles are at risk of injury or death from human activities.
There are 41 species of amphibians and 61 species of reptiles native to Illinois. The species most likely to be encountered near homes in Illinois are listed below by their common names. Habitat, natural history, distribution, and status information about any amphibian or reptile native to Illinois is available in the Illinois Natural History Survey's Field Guide to Amphibians and Reptiles of Illinois.
