‘Weird’ lizards reported in St. Charles Parish

Brown lizards or anoles are showing up in area yards and are likely an invasive species from Cuba and Haiti.

When the Trauths spotted “weird” lizards sunning themselves on their stepping stones in their front yard in Boutte, it raised a few questions.

“My husband (Buddy) and I were driving into the driveway one day when he slammed on the brakes and said, ‘Did you see that?! It was as big as a dragon,’” said Abby Trauth. “Since that day, we’ve been amazed at how big these lizards are. They’re much bigger than our usual green lizards and wayyyy faster.”

Actually, the biggest one they’ve seen is 6-1/2 to 7 inches long.

Well, they aren’t big as dragons (they don’t exist), but if there was such a thing they might look like larger versions of these rugged lizards or anoles.

“I’ve grown up in St Charles Parish and this is the first year that I’ve seen such an exotic looking animal (aside from an alligator) in my yard,” Trauth added.

That’s because they’re the latest invasive species reported in St. Charles Parish. Earlier, residents began reporting the bright pink eggs from apple snails in area waterways.

Barry Guillot, Harry Hurst Middle Wetland Watchers teacher, said the lizards are likely from Cuba or Haiti.

This invasive species apparently came into the U.S. from plant nurseries more than 15 years ago. Guillot said he believes the brown anoles were here before Hurricane Katrina.

“There’s no environmental damage unless eating bugs and mosquitoes is bad,” Guillot said. “They look a lot like the green anoles except during breeding season when they get the crest. Green anoles also get the crest during breeding season. They are harmless to people and pets.”

It’s a matter of brown versus green lizards.

These brown lizards were reportedly first seen in Florida, but it wasn’t until 1988 when it started being seen in larger numbers, Guillot said. Green lizards are indigenous to Louisiana, but the brown ones are apparently gaining in number because they can tolerate more heat in a number of hotter-than-normal summers.

In Boutte, Trauth’s neighbor told her he’d noticed the brown lizards for at least a year, but that it appeared the brown and green lizards were co-existing.

The scientists noticed them, too.

The green lizards are evolving with bigger, stickier toes to evade the more aggressive Cuban invaders. They compete for food and will eat one another’s young, but the green lizards developed the ability to climb higher in just the last 15 years.

But Trauth isn’t concerned, adding, “They’re probably only good for mosquito killing, which is great.”

Will brown replace green?

  • Anoles or brown lizards from Cuba and Haiti were reportedly first seen in Florida in 1887. By 1988, they are reported in larger numbers in the U.S.
  • Green lizards are forced to evolve to evade these more aggressive brown lizards. They are documented developing larger, stickier toe pads to live in higher parts of trees.
  • The brown lizards look tougher like they have body armor and are bigger. They bear impressive patterns for camouflage.

  1. My front bushes are full of the brown lizards. Some have stripes and some look like polka dots. They are all really fast! One green lizard is really big and looks like his face was in a fight. I also have a picture of a red headed lizard that I only saw that one time. I was never afraid of green lizards until I started seeing all those other variations. Someone I know said those brown lizards have been in Mimosa Park for years. Guess they just recently made it to the front of Mimosa.

  2. I have a picture of a brown lizard that has a ridge on it’s head and back!
    I could share it.

  3. I’d like to know what scientist said they evolved the bigger toe pads, and who did that study? Green anoles have always had the ability to go up in trees, just have to stay up there now because of the competition. the brown have been in Metairie since at least the early 90’s and in my yard, the greens still hunt below tree level, right along side of the browns.

  4. i catch these lizards all the time. they can eat up to 25 mosquitos in one hour. i have a pet one too.

    I have the exact same lizards in my yard. I don’t see that they are harming our anything and ive always studied them since i was young. these lizards are fun to catch and i even have a pet and they eat up to 18 mosquitos in ten minutes.
