The Caterpillars of this moth are an international pest in beehives, tunneling through the combs, feeding on pollen, wax and honey. Their preference is for abandoned hives, or hives where the colony has been weakened. As well as eating wax, they have also been found to be able to digest polytheene plastic
The caterpillars are a pale honey colour with a brown head. They are used to study insect physiology, and they make excellent bait for fishing. They are often used for the study of Nematodes.
The Caterpillars make white cocoons in the hive, which shield the orange pupa.
The adult moth has brown forewings each with vague markings, and a broad red band along the inner margin containing black spots. The hindwings are white. The moth has a wing span of about 3 cms. The moths are capable of hearing sounds up to 300KHz, which includes the range commonly used by bats to echo-locate moths.
The female moth often lays over 1,000 eggs, usually in batches of about 100. They are laid in cracks or corners. The eggs are also a pale honey colour, oval, and about 0.5 mm across. They are well camouflaged and easily overlooked.
