Diet

Stenocercus catherineae is primarily insectivorous, feeding on a diet rich in various invertebrates. Its food preferences include ants, beetles, and other small insects, making it an important player in controlling insect populations within its ecosystem. This lizard has adapted its hunting strategies to be opportunistic, utilizing both active foraging and ambush techniques to capture its prey. Frequently observed foraging in leaf litter or among rocks, it employs a sit-and-wait strategy, remaining still until an unsuspecting insect comes within range.

Moreover, Stenocercus catherineae has developed a high degree of visual acuity, enabling it to detect movement effectively among the foliage. This ability is critical, not only for hunting but also for avoiding predators. The combination of camouflage provided by its coloration and its keen eyesight makes this lizard a formidable presence in its ecological niche.

During periods of abundance, particularly after rainstorms which stimulate insect populations, Catherine’s spiny lizard may increase its foraging activity, taking full advantage of this bounty. This feast-or-famine style of eating underscores the importance of insect populations in these montane ecosystems, as they form the cornerstone of the food web upon which numerous species depend.

Reproduction

Reproductive behaviors in Stenocercus catherineae are fascinating and highlight the complexity of lizard life cycles. Breeding typically occurs during the warmer months, where males can often be seen performing various courtship displays to attract females. These displays consist of colorful body posturing and physical displays that emphasize their size and fitness, crucial elements for successful mating. The courtship rituals not only enhance male visibility to potential mates but also serve to deter rivals, establishing dominance between males.

Once a female is attracted, mating occurs, leading to the fertilization of eggs internally. Unlike many other lizard species that lay eggs, Stenocercus catherineae is oviparous, meaning it lays eggs in a secluded nesting site that typically consists of loose soil or decaying organic material. This nesting behavior is crucial for protecting the eggs from predators as well as environmental factors.

The incubation period for the eggs can vary depending on environmental conditions, but it generally lasts around 60 to 90 days.
