Waxworms are the larvae of the wax moth, which belong to the family Pyralidae. If left to their own devices, they will pupate and turn into wax moths, which are small moths that dont live very long and are still edible for animals if you want to feed them off. Waxworms are medium-white caterpillars with black-tipped feet and small, black or brown heads. In the wild, they live as nest parasites in bee colonies and eat cocoons, pollen, and shed skins of bees, and chew through beeswax, thus the name. Waxworms are a commonly used food for many insectivorous animals and plants in captivity. These larvae are grown extensively for use as food for humans, as well as live food for terrarium pets and some pet birds, mostly due to their high fat content, their ease of breeding, and their ability to survive for weeks at low temperatures.

In summary, waxworms turn into wax moths if left to their own devices.
