Eating habits
Most geckos hunt at night. The common gecko eats beetles, butterflies, millipedes, crickets, and cockroaches. Many larger species, such as the Caledonian gecko, pursue young lizards, mice, and small birds.
Lizards feed on a wide variety of foods including fruits and vegetation, insects, smalltetrapods, carrion, and even (in the cases of large predator lizards) large prey such as deer.
