Waxworms - Galleria Mellonella (Greater Wax Moth) These are the larvae (Caterpillars) of the greater wax moth. Themoths live in old honeycombs and beehives. The moth and the caterpilars are readily eaten by terrarium animals but the moth does not eat so is of less nutritional value than the caterpillar (Waxworm). The waxworms arrive in wood shavings and do not require feeding, they will remain fresh for approximately a week.
