Diversity of Lizards in Florida

Common Native Lizards

You can find several native lizard species in Florida. The Green Anole (Anolis carolinensis), recognizable by its bright green coloration and dewlap, is common in gardens and forests. The Florida Scrub Lizard (Sceloporus woodi), which has keeled scales and a blue belly, is native to scrub habitats. Another native, the Six-Lined Racerunner (Aspidoscelis sexlineata), is known for its six distinctive yellow stripes running down its body and its incredible speed.

Invasive Lizard Species

Florida’s climate also supports various invasive lizard species. The Brown Anole (Anolis sagrei), originally from Cuba and the Bahamas, has outcompeted the Green Anole in many areas and can be identified by its brown body and orange-red dewlap. The Knight Anole (Anolis equestris), known for its larger size and green body with yellow markings, is another species that has established a presence in the state. Additionally, the Argentine Black and White Tegu (Salvator merianae), a large lizard from South America, poses a threat to native wildlife due to its invasive nature and significant appetite.

Native Lizard Species Spotlight

The American Green Anole

The American Green Anole, or Anolis carolinensis, is a small, tree-dwelling lizard native to Florida. It’s known for its vibrant green color, although it can change to brown depending on temperature and mood. These lizards measure between 5 to 8 inches in length, including their tail. The Green Anole is insectivorous, feeding mainly on small insects and spiders. You’ll often spot them in gardens, forests, and urban areas.

The Southern Coal Skink

The Southern Coal Skink, scientifically known as Plestiodon anthracinus pluvialis, is another native lizard species in Florida. They are smaller, typically reaching lengths of 4 to 6 inches. These skinks have smooth, shiny scales and are predominantly brown with dark stripes down their sides. They inhabit moist, wooded areas and leaf litter, making them less visible than other lizards. The diet of the Southern Coal Skink consists of insects and small invertebrates, contributing to a balanced ecosystem.

Invasive Lizards Threatening Local Ecosystems

The Cuban Brown Anole

The Cuban Brown Anole (Anolis sagrei) has rapidly spread through Florida’s urban, suburban, and natural areas. This small lizard, frequently found in gardens and on trees, outcompetes native species for food and habitat. The Cuban Brown Anole eats insects like ants, beetles, and spiders. Due to their aggressive nature, they displace the native Green Anole by occupying the lower parts of trees, forcing Green Anoles higher. The invasion of Cuban Brown Anoles disrupts the balance of local ecosystems.

The Argentine Black and White Tegu

The Argentine Black and White Tegu (Salvator merianae), a large and robust lizard, poses a significant threat to Florida’s wildlife. This species preys on a wide range of animals, including birds, eggs, small mammals, reptiles, and amphibians. Its remarkable adaptability allows it to thrive in various environments, from swamps to suburban areas. Active breeders, Argentine Black and White Tegus expand their population quickly, leading to heightened predation pressure on native fauna and disrupting ecosystems. Conservation efforts aim to control their spread and mitigate their impact on Florida’s ecosystems.

Public Impact and Human-Lizard Interactions

Adaptations in Urban Areas

Lizards in Florida often adapt to urban environments, finding shelter in residential areas and thriving in suburban landscapes. Green Anoles (Anolis carolinensis) frequently appear on walls, fences, and gardens, capitalizing on the warmth and safety these structures provide. Brown Anoles (Anolis sagrei) exploit man-made objects like cluttered yards, using these spaces to hide and hunt. These adaptations highlight the lizards’ ability to coexist with human development.

Residential areas attract lizards due to the abundance of resources and microhabitats. Cuban Brown Anoles (Anolis sagrei) find ample food sources in landscaped gardens and under outdoor furniture. Energy-efficient homes with good insulation may inadvertently create warm environments perfect for lizard activity. These adaptations not only demonstrate the resilience of lizards but also underline the importance of creating harmonious urban ecosystems.

Impact on Local Households

Lizards in urban settings often influence household dynamics, sometimes causing discomfort for residents. Green Iguanas (Iguana iguana), an invasive species, can damage plants and properties by consuming vegetation and burrowing underground. Homeowners frequently report seeing these large lizards on patios and in pools, leading to potential nuisance issues. It’s similar to how unexpected events can disrupt plans, like a motorcycle race in Italy altering the daily routines of local residents.

Small lizard species like the House Gecko (Hemidactylus frenatus) often enter homes, especially in tropical climates, drawn by indoor lighting that attracts insects. While these lizards are beneficial in controlling insect populations, their presence inside homes can be unsettling for some residents. Effective measures include sealing cracks and installing screens to minimize indoor encounters with lizards, much like using strategies to prevent unexpected disruptions in a football game or a baseball match.

Public health considerations arise due to the presence of lizards near households. Though generally non-venomous and harmless to humans, they can sometimes carry salmonella, posing a minor risk if handled improperly. Awareness and education about these interactions are crucial for maintaining a balance between human comfort and lizard conservation. Understanding these dynamics can be as enriching as exploring the cultural heritage of countries like France and Italy, where the coexistence of modern life and historical elements creates a unique and harmonious living environment.
