Michigan is often associated with its cold winters and lush forests, but it also hosts a surprising variety of lizard species. Whether you’re a nature enthusiast, a student, or a casual observer, understanding the types of lizards that inhabit Michigan can deepen your appreciation for the state’s biodiversity. This listicle covers the native and occasional sighting lizard species found in Michigan, providing detailed descriptions to help you identify and learn about these fascinating reptiles.
Eastern Fence Lizard (Sceloporus undulatus)
The Eastern Fence Lizard is one of the most common lizard species in Michigan, particularly in the southern parts of the state. Recognizable by its rough, spiny scales and distinctive blue patches on its belly, this lizard favors rocky areas, woodland edges, and sunny patches. Its ability to thermoregulate efficiently makes it a frequent sight during warm months, and observing one basking on rocks or logs offers a glimpse into Michigan’s resilient reptilian life.
Five-lined Skink (Plestiodon fasciatus)
The Five-lined Skink is a slender, agile lizard with five distinctive yellow or white stripes running down its back, making it easily identifiable. Found in deciduous forests, rocky slopes, and old logs, this skink is notable for its shiny, smooth scales and its ability to shed its tail to escape predators. Although less common than fence lizards, sightings in southern Michigan are increasingly reported, especially near wooded areas.
Common Five-lined Skink (Plestiodon fasciatus)
The Common Five-lined Skink shares many characteristics with its less common cousin but is distinguished by its more widespread presence and slightly darker coloration. It prefers moist, wooded habitats with ample leaf litter and fallen logs. Its curious, quick movements and tendency to hide under rocks make it a rewarding species for keen observers interested in Michigan’s herpetofauna.
Woodland Skink (Plestiodon lateralis)
While primarily found in the northern parts of Michigan and in neighboring states, the Woodland Skink occasionally appears in the southern regions during warmer months. This skink is characterized by its brownish color with light stripes and a preference for moist, shaded woodland environments. Its elusive nature and preference for dense underbrush make it a rarer find, but it plays an important role in controlling insect populations.
Northern Slimy Salamander (Plethodon grobmani)
Though technically a salamander, the Northern Slimy Salamander is often mistaken for a lizard due to its elongated body and limb structure. It inhabits moist, cool forests and is notable for secreting a slimy substance as a defense mechanism. Its dark coloration and preference for underground or leaf-litter habitats make it a fascinating, if less visible, part of Michigan’s herpetofauna.
Slender Glass Lizard (Ophisaurus attenuatus)
The Slender Glass Lizard is a legless lizard, often mistaken for a snake but distinguishable by its eyelids and external ear openings. It is rarely seen in Michigan, primarily in the southern regions, where it favors open, sandy, or grassy areas. Its translucent, nearly glass-like appearance during certain phases of its life cycle makes it a unique sight for dedicated herpetologists.
Green Anole (Anolis carolinensis)
The Green Anole is a small, vibrant lizard more commonly associated with the southeastern U.S., but occasional sightings in southern Michigan have been reported. Its bright green color and ability to change to a brownish hue help it blend into leafy environments. While not a native species, its presence indicates changing climate conditions and the adaptability of some lizard species in Michigan.
European Wall Lizard (Podarcis muralis)
Introduced to parts of Michigan through pet releases and escapes, the European Wall Lizard has established small populations in urban and rocky areas. Recognizable by its variable coloration, often with a pattern of spots and blotches, it thrives on walls, rocks, and urban landscapes. Its adaptability makes it a species worth watching for those interested in non-native reptiles in Michigan.
How to Choose
When selecting which lizard to observe or study, consider factors like habitat preference, coloration, size, and behavior. Native species like the Eastern Fence Lizard and Five-lined Skink are more likely to be encountered in natural settings, while non-native or rare species such as the European Wall Lizard require specific environments or luck. Your interest level, the environment you explore, and the lizard’s activity patterns all influence which species you’re most likely to see.
Frequently Asked Questions
- Are there venomous lizards in Michigan? No, Michigan does not have venomous lizard species. All native lizards are harmless to humans.

- Can I keep Michigan lizards as pets? Most native Michigan lizards are protected by law and should not be removed from their habitat. Always check local regulations before considering pet ownership.
- Are lizards in Michigan endangered? Some species, like the Five-lined Skink, are considered species of special concern due to habitat loss, but overall, most native lizards are stable.
- How can I attract lizards to my yard? Providing rocks, logs, and leaf litter, along with avoiding pesticides, creates a welcoming environment for native lizards.
Final Thoughts
Michigan’s reptile diversity may be modest compared to warmer southern states, but it offers a fascinating glimpse into the resilience and adaptability of lizards in cooler climates. Whether you’re spotting the spiny-backed Eastern Fence Lizard or the elusive skinks darting through leaf litter, each species contributes uniquely to Michigan’s ecosystems. Respect their habitats, observe quietly, and appreciate these often-overlooked creatures that enrich the state’s natural tapestry.
