Why this diet?
Leaves, flowers, seeds and shoots of desert plants, with occasional insects. This diet supports Sun Budget because plant food is stationary — it can be reached in a short, pre-warmed trip rather than a chase.
06
Activity, rest, and lifespan
Ornate Spiny-tailed Lizards are strictly diurnal, retreating into rock crevices or burrows overnight and through the hottest part of the afternoon.
They can live for twenty years or more, so Sun Budget becomes practised routine — a lizard knows its basking rock, its retreat, and the timing between them.
07
Ornate Spiny-tailed Lizard reproduction
Females lay a clutch of eggs in a burrow in late spring, and hatchlings emerge already able to bask and forage. Offspring fit the principle because a hatchling must learn the basking-and-retreat rhythm before anything else.
Males are far more brightly coloured than the duller brown and cream females. The difference is a display, and it is affordable precisely because the lizard is warm and visible on rock anyway.
