During the mating season, beginning in April, males flash their blue patches to attract females. Males also have anal glands that secrete a pheromone during and after breeding season to attract females. After mating males and females no longer associate. Males may seek other mating opportunities.
Mating System: polygynous
Mating occurs from April to August. Young females lay one clutch of 3 to 13 eggs. Older females lay 2 to 4 clutches per year. Eggs hatch from June to September. The eggs are laid below 3 to 7 cm of soil so that the moisture and temperature remain constant. It may take 10 weeks for the eggs to hatch after they have been deposited. The offspring reach maturity at 1 year of age.
Breeding interval: Young eastern fence lizards lay one clutch per year while older females can lay 2 to 4 clutches per year.
Breeding season: Breeding occurs from April to August.
Range number of offspring: 3 to 13.
Average gestation period: 8 weeks.
Range age at sexual or reproductive maturity (female): 1 to 2 years.
Range age at sexual or reproductive maturity (male): 1 to 2 years.
Key Reproductive Features: iteroparous ; seasonal breeding ; gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization ; oviparous
Female eastern fence lizards increase body size if food is available, which is directly correlated to an increased clutch size. After laying her eggs females leave their young to fend for themselves.
Parental Investment: no parental involvement; pre-fertilization (Provisioning, Protecting: Female); pre-hatching/birth (Provisioning: Female)
