About Aspidoscelis hyperythrus (Cope, 1863)
Aspidoscelis hyperythrus has five or six light-colored stripes running along its black, brown, or grey dorsal side. The middle stripe may be forked at both ends. The ventral side of this species is whitish-yellow or cream, and it has an orange throat, though females and juveniles may not have this orange marking. Its head ranges from yellow-brown to olive in color, and its tongue is forked and flicked continuously. The species has a snout-to-vent length of 5–7.2 centimetres, or 2.0–2.8 inches. Juveniles have cobalt blue legs and tails. The entire ventral surface, including the tail, of males may be orange; gravid females may also have some orange, particularly along the lower jaw. The species' colors are most distinct during the breeding season. Males have larger femoral pores than females. Aspidoscelis hyperythrus is native to southern California in the United States, and to the states of Baja California and Baja California Sur in Mexico.
