The most common lizards in Texas gardens are the anoles, often mistakenly called chameleons. They are usually bright green, and the males have a pink throat fan that they display when showing off for the ladies. They can change color to brown. They eat insects and add beauty to the garden.
Geckos are great lizards for insect control. There are at least three species here in Texas. Asian geckos are smooth-skinned and about 4 to 5 inches long at maturity. The Mediterranean gecko is the same size but has bumps and a ringed tail. Both love to eat young roaches, grasshoppers, katydids, ants, and other insects. They are pale and translucent and have large lidless eyes. Their toes have broad pads and claws extending beyond the pads. The Mediterranean gecko was introduced to Texas several years ago and has now naturalized across at least half the state. This is the most commonly seen gecko because it likes to live around lighted buildings so it can eat the insects that are attracted to the light. Breeding takes place for four or five months in the spring. They lay one to two eggs under shutters or even in the bases of light fixtures. The third species is the tokay gecko, also an Asian import. It is much larger and much more aggressive; although naturalized in some parts of Texas, we do not recommend its release. Unlike the small geckos, it can give you a painful bite. It feeds on insects but also eats small geckos and other animals.
The Mediterraneans can be bought at pet and feed stores. They should be protected and released as an important part of your organic pest control program.
