Waxworms (or Galleria mellonella ) are the larvae of a type of moth, commonly used as food for insectivorous reptiles, including lizards, geckos, and chameleons. They are high in fat and protein, making them a source of energy for reptiles, but this high fat content means they should be fed in moderation to avoid obesity.
 Waxworms are often prized for their tender texture and ideal size, and can be used as a treat or dietary supplement. It is recommended to feed them before offering them to reptiles to maximize their nutritional value (a practice called "gut-loading"). Due to their high fat content, they should not be the main food, but rather an addition to a balanced diet.
