Brown lizards are a common sight in Florida, particularly in the southern and central regions of the state. These small, agile creatures are often seen scurrying across sidewalks, patios, and gardens, and can be found in a variety of habitats, including urban and natural areas. The most common species of brown lizard found in Florida is the Brown Anole (Anolis sagrei), a non-native species that has established itself in the state over the past few decades.
Introduction to Brown Lizards in Florida
The Brown Anole is a small to medium-sized lizard, typically growing to a length of 5-8 inches, including its tail. It has a brown or grayish-brown color, with a distinctive pinkish-colored dewlap on its throat, which it uses to communicate with other anoles. Brown anoles are known for their ability to change color, and can darken or lighten their skin to blend in with their surroundings or to regulate their body temperature. They are also skilled climbers, and can often be found basking in the sun on trees, fences, or other elevated surfaces.
Habitat and Distribution
Brown anoles can be found in a variety of habitats in Florida, including urban and natural areas. They are commonly found in gardens, parks, and other areas with vegetation, as well as in trees and on buildings. They are also found in more natural areas, such as forests, grasslands, and wetlands. Brown anoles are native to the Caribbean and Central America, but have been introduced to Florida and other parts of the southeastern United States through the pet trade and other human activities. They are now established in many parts of the state, and can be found as far north as Jacksonville and as far south as Key West.
| Species | Length | Weight | Habitat |
|---|---|---|---|
| Brown Anole | 5-8 inches | 0.07-0.14 oz | Urban, natural areas |
| Green Anole | 5-8 inches | 0.07-0.14 oz | Forests, wetlands |
| Knight Anole | 10-12 inches | 1.4-2.8 oz | Forests, urban areas |
Diet and Foraging
Brown anoles are insectivores, and feed on a variety of small insects, including ants, beetles, and flies. They are also known to eat spiders, snails, and other small invertebrates. Brown anoles are active foragers, and can be seen running across surfaces, searching for food. They are also skilled climbers, and can climb trees and other vertical surfaces to catch insects and other prey.
Reproduction and Lifespan
Brown anoles are prolific breeders, and can produce multiple clutches of eggs per year. Females lay their eggs in protected areas, such as under rocks or in vegetation, and the eggs hatch after several weeks. The young anoles are small and vulnerable, but grow quickly, reaching maturity in just a few months. Brown anoles can live for several years in the wild, although their average lifespan is around 1-2 years.
- Brown anoles can breed year-round in Florida, but the peak breeding season is typically in the spring and summer.
- Females can lay up to 5 eggs per clutch, and may produce multiple clutches per year.
- Young anoles are born with a small, pinkish-colored dewlap, which darkens as they mature.
Are brown lizards in Florida poisonous?

In conclusion, brown lizards are a common and fascinating species in Florida, and can be found in a variety of habitats throughout the state. While they may be considered an invasive species, they can also serve as an important food source for native predators, and can be an interesting and entertaining species to observe and study.
