If you’re interested in Connecticut’s reptile diversity, especially lizards, this list covers the most common species you’ll encounter in the state. Whether you’re a nature enthusiast, a student, or a homeowner curious about local wildlife, understanding these lizards can help you identify them and appreciate their role in Connecticut’s ecosystems. Here’s a detailed look at each species, what makes them unique, and why they matter.
Eastern Fence Lizard (Sceloporus undulatus)
The Eastern Fence Lizard is one of Connecticut’s most widespread lizards. Recognizable by its rough, spiny scales and distinctive blue patches on the belly, especially in males, it favors rocky areas, woodlands, and suburban yards. This species is beneficial because it preys on insects like beetles and ants, helping control pest populations. They are diurnal, active during warm months, and often seen basking on rocks or logs.
Five-lined Skink (Plestiodon fasciatus)
The Five-lined Skink is notable for its sleek body and five distinctive yellow or white stripes running from head to tail. Juveniles display bright blue tails, which fade as they mature. Found in wooded areas, leaf litter, and rocky slopes, they are excellent at hiding from predators. Their diet mainly consists of insects and small invertebrates, making them vital for maintaining insect populations in forested habitats.
Common Lizard (Zootoca vivipara)
Though less common, the Common Lizard, also known as the Viviparous Lizard, occasionally appears in Connecticut’s wetlands and grassy areas. It is small, with a brown or gray coloration, often with darker spots or stripes. Unlike many other lizards, it gives birth to live young, an adaptation to cooler climates. Its presence indicates healthy, moist environments with ample insect prey.
Northern Fence Lizard (Sceloporus septentrionalis)
Similar to the Eastern Fence Lizard, the Northern Fence Lizard is found in the northern parts of Connecticut. It prefers rocky outcrops, forest edges, and sunlit areas. Males display vibrant blue patches on their bellies and throats during the breeding season, attracting mates. Their diet mainly includes insects and spiders, and they are quick to dart into crevices when threatened.
Green Anole (Anolis carolinensis)
The Green Anole, often called the American chameleon, occasionally ventures into southern Connecticut. It is small, with bright green or brown coloration, and can change color slightly to blend into surroundings. Preferring shrubs, fences, and garden plants, it’s a favorite among backyard enthusiasts. Its diet consists of small insects, and it is appreciated for its graceful movements and adaptability.
Six-lined Racerunner (Aspidoscelis sexlineata)
This fast-moving lizard is more common in southern parts of Connecticut but occasionally found further north. It has a slender body with six distinct lines running from head to tail and is known for its speed. Preferring sandy or rocky habitats, it feeds on insects and small invertebrates. Its agility helps it escape predators quickly, making it a fascinating species to observe.
Slender Glass Lizard (Ophisaurus attenuatus)
The Slender Glass Lizard is actually a legless lizard, often mistaken for a snake. It has a long, smooth body with a shiny, translucent appearance, and it prefers open grasslands and sandy soils. They are non-venomous and feed on insects and small invertebrates. Their ability to break off tail segments helps them escape predators, a unique defense mechanism.
Eastern Glass Lizard (Ophisaurus ventralis)
Similar to the Slender Glass Lizard, the Eastern Glass Lizard is found in southern Connecticut’s open areas. It has a slightly broader body and is known for its glassy, translucent appearance. It often burrows or hides under rocks and logs, feeding on insects and small invertebrates. Its legless form and secretive nature make it a rare sight for most observers.
How to Choose
When selecting a lizard to observe or keep, consider factors like habitat compatibility, size, activity patterns, and dietary needs. For instance, if you want a lizard that thrives in rocky, sunny areas, the Fence or Skink species are ideal. Always prioritize native species and ensure you understand their care requirements if keeping as a pet. Recognizing their behavior and habitat preferences will help you enjoy and protect these fascinating creatures.
