and are found at greater heights. Frilled lizards do not enter torpidity during the dry season, but they can greatly reduce their energy usage and metabolic rate in response to less food and water. Body temperatures can approach . The species will bask vertically on the main tree trunk in the morning and near the end of the day, though in the dry season they cease basking at a lower body temperature to better maintain energy and water. When it gets hotter during day, they climb higher in the canopy for shade. Frilled lizards will use large trees and termite mounts as refuges during wildfires. After a forest is burnt, the lizards select trees with more continuous canopies. Frilled lizards primarily feed on insects and other invertebrates, and very rarely take vertebrates. Prominent prey includes termites, ants and centipedes; termites are particularly important food during the dry season, and moth larvae become important during the wet season. Consumption of ants drops after early dry season fires but rises following fires later in the season. This species is a sit-and-wait predator: it watches for potential prey from a tree and, upon seeing it, climbs down and rushes towards it on two legs before descending on all four to grab and eat it. After feeding, it retreats back up a tree. Frilled lizards face threats from birds of prey and larger lizards and snakes. When threatened, the species erects its frill to make itself look bigger. This display is accompanied by a gaping mouth, puffing, hissing, and tail lashes. The lizard may also flee and hide from its predators. Several species of nematode infest the gastrointestinal tract. There is at least one record of an individual dying of cryptosporidiosis. Frilled lizards can breed during the late dry and early wet seasons. Competing males display with gaping mouths and spread frills. Fights can ensue, in which the lizards pounce and bite each other's heads. The female digs a shallow cavity to leave her eggs. They can lay multiple clutches per season, and the number of eggs in a clutch can vary from four to over 20. The incubation period can last two to four months, with milder temperatures producing more males and more extreme temperatures producing more females. Hatchlings have proportionally smaller frills than adults. Lizards grow during the wet season when food is more abundant, and males grow faster than females. Juvenile
