Leopard geckos are opportunistic carnivores, meaning that they will eat whatever they can catch. Since in captivity their diet is regulated it is recommended that they are fed in the late afternoon to early evening because they are nocturnal animals and that is when they are starting to get active. The most common insects fed to leopard geckos are mealworms, crickets, Dubia roaches, waxworms, and hornworms. Not all of these options have the same nutritional content. The best food for your gecko is mealworms, crickets, and roaches because waxworms and hornworms are high in fat and low in protein so they should be given as treats instead of as a daily meal. Another aspect of a leopard gecko’s diet that is very important is supplements. It is very typical to give leopard geckos a calcium supplement that also contains vitamin D3 because leopard geckos need calcium for bone health, tooth health, tissue regeneration, maintaining muscle function, and supporting healthy metabolism. This supplement typically comes in the form of powder, and you can dust the worms, crickets, or roaches in the powder before you feed them to your lizard to make sure they are getting all the nutrients they need!
