Page "Eumeces fasciatus" Paragraph 11

Adult male five-lined skinks exhibit complex courtship and aggressive behavior.

Although males tolerate juveniles and females in their territories, they actively defend these areas against other males.

Vomeronasal analysis of chemical cues and recognition of sex specific visual stimuli, including tail and body coloration, aid in the identification of gender.

Evidence suggests that males may rely more on contact phermones than volatile airborne molecules in the identification of conspecifics.

Courting males grasp the necks of receptive females in their jaws after approaching them from the side.

Using the tail to align cloacal openings, males initiate copulation by inserting one of the two hemipenes into the female's cloaca.

Copulation events typically last four to eight minutes.
