Behaviour

Brown anoles live close to the ground and are bold, displaying from fence posts with head bobs and flared throat fans. They arrived in Florida from Cuba and the Bahamas and have spread north, carried in nursery plants.

Why they matter

Where brown anoles move in, green anoles shift higher into trees to avoid competition and being eaten when young. Brown anoles also eat many insects and are themselves food for birds and snakes.

Reproduction and lifecycle

Eggs — One at a time, every week or so through the warm months
Nest — Laid in moist soil and leaf litter
Incubation — About 4 to 8 weeks
Hatchlings — Small and independent
Maturity — Within a year
Lifespan — A few years

Living around people

  • Checking nursery plants before moving them north slows their spread.
  • Never release pet anoles.

Misconceptions

  • All anoles are native. The green anole is Georgia's native anole; the brown anole came from the Caribbean.
