Lizards of Wisconsin

Eggs and Stuff

Wisconsin's lizards breed shortly after emerging from hibernation. About a month after the eggs are fertilized, a female lizard will lay her eggs. They will incubate for anywhere from 30-60 days, depending on the weather.

Lizards lay their leathery-shelled eggs in moist place because the eggs need to take up water as they develop. In some species, the females leave their eggs after they are laid. Females of both Wisconsin skinks and the western slender glass lizard remain with their eggs. A female will curl itself around the eggs to keep them moist and she may occasionally turn them. If the eggs become too cool, the female may go out and bask in the sun, and then return to warm her eggs.

What's on the Menu?

Wisconsin's lizards are primarily insectivores (meaning they eat insects). Sometimes they will eat other invertebrates. The slender glass lizard may occasionally eat groundnesting bird eggs and small mice.
