Eastern Fence Lizard
(Sceloporus undulatus)
These nongame insectivorus lizards inhabit cold desert and submontane zones. They require rocky, deep soil areas with openings to allow basking. Diurnal activity occurs at an average air temperature of 76°F.
Breeding occurs from April- August, after which 3-13 eggs are laid in moist soil. Yearlings deposit only 1 clutch, while adults deposit 2-4 clutches. Eggs incubate for 2 months. Only the northern plateau subspecies (S.u. elongatus) inhabits southeastern Utah.
