The female Banded Gecko tend to be larger than the male ones.
Courtship is initiated by the male approaching the female, usually from behind with his body held close to the ground and tail waving. He makes an initial bite on the female’s tail, flank, or neck. If the female is receptive and remains motionless, he advances forward with jerking movements, eventually mounting and shifting his bite to the neck or shoulder. The female responds by raising her tail, and the male entwines and brings his cloaca beneath hers. The cloacal spurof the male (Figs. 4-5) appears to serve to draw back the female’s posterior cloacal lip on the side where the hemipenis is inserted (Greenberg 1943).
Coleonyx is a genus of terrestrial geckos commonly referred to as banded geckos. Species of Coleonyx are found in the southwestern United States, Mexico, and Central America. Banded Geckos enjoy dry, warm weather which is why they are typically found in the Peninsular Desert.[1] They are relatively small lizards, measuring about 5–6 in (13–15 cm) inches in total length (including tail). They are nocturnal and are found primarily in dry, rocky habitats. Banded Geckos have preyed by snakes, their main predators being rattlesnakes and glossy snakes. Banded Geckos can decipher how they should react when they obtain a chemical cue based on their knowledge of the predator. A main resource they use to distract the predator is losing their tail or escaping quickly.[2] Banded Geckos possess heteromorphic euchromatic sex chromosomes which play a large role in their historical contingency.
