Green anoles rarely consume anything other than insects. Crickets are the most popular feeder insect for anoles, because they are easy to find, inexpensive, and nutritional. Also, crickets are fast-moving insects, which helps them appeal to anoles because they can chase and capture their prey. An appropriately-sized cricket will be about half as long as your anole’s head.
Mealworms are another good food choice for green anoles. To feed mealworms, place a dozen or so in a steep-sided glass dish that is buried evenly with the top of the substrate. Keep in mind that not all green anoles will take mealworms, as they are slow-moving and don’t provide much of a chase for the lizards.
Powdered vitamin and mineral supplements will make a good addition to your green anole’s diet. An easy way to do this is to coat the crickets with the powder supplement before feeding them to your anole. Supplements should be given about once per week.
Most adult anoles will eat about five crickets per day and maybe one mealworm. If your anole suddenly refuses a meal, you may be overfeeding him. If this happens, skip a feeding and try feeding slightly less in the future. Feeding at the same time every day and at the same location in the cage is a good idea, as it provides continuity for your pet, and most green anoles will learn the schedule and begin to anticipate feeding time by standing in the feeding area of the cage.
