Fun Southern Flannel Moth Facts For Kids

Do you want to learn interesting facts about a particular golden moth? In this article, you will learn about the intriguing southern flannel moth.

Found across the United States of America, particularly in the south-eastern part of the country, the southern flannel moth is a small moth of the genus Megalopyge.

Found in regions from New Jersey to Florida, Mexico, and parts of Central America, the golden moth is a harmless animal with a short life span. The adult moths are covered in golden hairs, with yellow and black wings, two white antennae, and teeth on both sides of their antennae.

The caterpillars, often known as puss caterpillars or asp caterpillars, are about 1.5 in (3.81 cm) in length and covered in fur-like hairs that taper at the end to form a tail.

Although they can appear harmless or even cute from a distance, these hairs contain venom, which is released when they are touched. The stings of the caterpillars can cause redness and swelling, and in some cases can result in such serious pain in the limbs, that it even requires medical aid.

The adults and caterpillars feed on leaves of deciduous trees and garden plants.

Adults brood two or three times a year and lay eggs on leaves and twigs, and cover them with hair to keep their babies safe.

In the early stages, the caterpillars often move from tree to tree looking for new leaves to feed on. This movement takes place before the cocoons are formed.

The caterpillars go through multiple molts inside the cocoon, before it finally breaks and the adult moths emerge out of their shells.

The wings range in size between 1 - 1.5 in (2.4 and 3.6 cm). Their yellowish wings have black margins and white hair-like setae on the basal part. These hair-like setae are deeply divided scales.
