The diet of the ocellated spinytail consists mainly of plant matter, particularly Acacia trees, which they climb to feed on (1) (2) (4). Occasionally, young individuals in captivity have also been observed to feed on insects and other invertebrates (2).
The ocellated spinytail is active during the day, usually emerging from its refuge mid-morning and remaining active until well after noon (4). This species often lives in small colonies (1).
The breeding biology of the ocellated spinytail is not well known. However, Uromastyx species generally lay eggs in clutches of 8 to 20, with the eggs hatching after 8 to 10 weeks. The eggs are laid in the female’s burrow in late spring to early summer, or at the start of the dry season, and the hatchlings stay in the burrow for several weeks before leaving to establish a burrow of their own (2).
Like other small Uromastyx species, the ocellated spinytail is likely to reach sexual maturity at 2 to 3 years of age, and may live to around 25 years old (2).
