Abstract
We quantified sexual size dimorphism, diet and reproduction in the Starred Agama, Laudakia stellio, in northern Sinai. Males were larger than females in snout-vent length and head index. The species is a sit-and-wait predator and feeds on insects, mainly coleopterans. About 30% of stomachs included plant material. No difference between sexes existed in terms of prey size preference. The reproductive season is seen to be year round with no distinctive seasonality. The smallest sexually mature female measured 92 mm SVL, whereas the smallest sexually reproductive male was 89 mm SVL. Clutch size ranged from 6 to 18 eggs.
