Habitat
This lizard is terrestrial and sometimes arboreal; inhabits frequently fragmented dry forest, arid environments, barren desert and desolate areas across the Indo-Gangetic plains.[1]
Habit
This lizard is diurnal and crepuscular. It shelters in burrows close to the roots of thorny bushes.[1] Generally it is found sitting on stones, but it can climb up shrubby vegetation. It is sluggish in movements, often not attempting to escape when approached.[3] It is a docile species.[5]
Diet
This lizard is mainly insectivorous; feeding on grasshoppers and their nymphs, earwigs, beetles, bugs, arthropods and spiders.[3] Sometimes it also eats flowers.[1]
Reproduction
This lizard is oviparous; the breeding season extends from April to June; it lays four to six hard shelled white eggs in burrows under the roots of vegetation.[1]
Importance and uses
There are no known practical uses of this species, but it plays a role in the eco-system by eating various types of insects and otherwise.
Threat to humans
This lizard is non-venomous and completely harmless to humans.[6]
Etymology
The species-name minor, a Latin word, meaning 'less' or 'smaller', also referring to the smaller size of this agamid.[7]
This lizard has a reputation for being particularly harmful, which is totally baseless and has contributed much to its depletion.[1]
