Maryland is home to a diverse array of lizard species, many of which can be spotted across various habitats from suburban yards to natural woodlands. This list is perfect for wildlife enthusiasts, students, or homeowners curious about the local reptile population. Whether you’re a casual observer or a budding herpetologist, understanding the common lizards of Maryland can enhance your outdoor experience and help you identify these fascinating creatures.
Common Five-lined Skink (Plestiodon fasciatus)
The Five-lined Skink is Maryland’s most widespread lizard, recognizable by its glossy black body adorned with five bright yellow or white stripes running from head to tail. Adults typically measure about 8 to 11 inches long and are often seen basking on rocks, logs, or in leaf litter. Their active nature and striking appearance make them a favorite among local herpetofauna, and they play a vital role in controlling insect populations.
Coal Skink (Plestiodon anthracinus)
The Coal Skink, slightly smaller than the Five-lined Skink, is distinguished by its dark, almost black coloration with a faint, light-colored stripe along its side. It prefers moist, rocky areas near streams and wetlands, where it hides under stones or in crevices. Its secretive behavior and preference for humid habitats make it less visible but no less important in Maryland’s ecological web.
Common Lizard (Anolis carolinensis)
Although more often associated with the southeastern U.S., the Green Anole occasionally appears in southern Maryland. Known for its vibrant green color and ability to change to brown, this small lizard (about 5-8 inches) is highly arboreal, often seen on shrubs and trees. Its agility and color-shifting ability make it a fascinating species for observation, especially in suburban gardens.
Slender Glass Lizard (Ophisaurus attenuatus)
The Slender Glass Lizard, a legless lizard, resembles a snake but can be distinguished by its eyelids and external ear openings. Reaching lengths of up to 4 feet, it prefers open grassy areas, prairies, and fields. Its transparent, glass-like tail that can detach when caught is a remarkable adaptation, and it feeds primarily on insects and small invertebrates.
Northern Fence Lizard (Sceloporus undulatus)
Occasionally found in southern Maryland, the Northern Fence Lizard is characterized by its rough, spiny scales and distinctive dark, wavy patterns on its back. Usually about 4-7 inches long, it favors rocky outcrops, fence posts, and sunny patches. Its energetic behavior and territorial displays make it an interesting species for observation in more developed areas.
Eastern Glass Lizard (Ophisaurus ventralis)
This legless lizard is often mistaken for a snake but has movable eyelids and a distinct forked tongue. Typically found in sandy or grassy fields, it can reach lengths of up to 4 feet. Its slender body and tail help it escape predators, and it primarily preys on insects and spiders.
Green Anole (Anolis carolinensis)
The Green Anole is a small, vibrant lizard that is common in Maryland’s southern regions. It is highly adaptable to urban and suburban environments, often seen on fences, garden plants, and tree trunks. Its ability to change from bright green to brown and its territorial behavior make it a captivating species for backyard wildlife watchers.
Six-lined Racerunner (Aspidoscelis sexlineata)
Though more common further south, the Six-lined Racerunner has been documented in Maryland’s southern counties. Recognizable by its long, slender body and six light stripes, it is one of the fastest lizards in North America. Preferring open, sandy habitats, it hunts insects and small invertebrates, making it a beneficial presence in pest control.
How to Choose
When selecting which lizard to observe or study, consider factors such as habitat preference, size, coloration, and behavior. For example, if you’re interested in more visible, colorful species, the Green Anole or Five-lined Skink are excellent choices. For those fascinated by unique adaptations like limb reduction, the Glass Lizard offers a compelling subject. Understanding the environment you frequent will help you identify which species are most likely to be encountered and how to approach observing them responsibly.
