When you hear moth, a dark-colored insect comes to your mind, right? But, would you ever imagine that a moth could be as beautiful as a butterfly?

Meet the ailanthus webworm moth, which looks like a jewel, with bright orange bands with clusters of white spots enclosed in black rings! How beautiful nature's creation is, which looks like a beetle when stationary and resembles a wasp while flying!

Its name, ailanthus webworm moth, may sound intriguing. Belonging to the ermine family of webworms, it infests host plants, paradise trees, and the tree of heaven. Originating in South Florida, it is spread across the United States.

It is known for its unique coloration and body. Though many other moths are nocturnal, the webworm moth (Atteva aurea) is diurnal. This insect feeds on the nectar of the flowers during the daytime and makes an excellent pollinator.

The tree of heaven was thriving in colder climates than Florida. Hence, this moth hopped on board with them and moved toward North America. It has cousins like gypsy moth and luna moth, which you can explore.

The female ailanthus webworm moth dies after laying eggs during the mating season. It is interesting to know that only one generation of these ermine moths lives every year. The single moth takes about four weeks from the egg stage to the egg-laying adult stage. Some studies have shown that male moths have a long life span.

How do they reproduce?

Mating happens in the morning, and the female ailanthus webworm moth lays an abundance of eggs in the evening. These eggs are not in clusters but stay individually in the larval silk webs created on the bunch of leaflets.

The eggs can live on other larvae within the same web, which houses several generations of eggs in different stages, converting into a large communal web.

Many larvae (caterpillars) feed on the leaves, flowers, and seeds, staying within the web safely and eventually pupating into the chrysalis and then adults in the same location. Adults start to emerge from late spring until fall.

How do they communicate?

In a way, their coloration is itself a communication to predators about their toxicity. But there are certain species of eared moths, which have evolved organs that produce sounds to keep their predators away.

They also frequently have a low-range, low-intensity, ultrasound whisper made by males for courtship indicating a sexual sound communication. In addition, some moths release pheromones to attract females.

What are the male and female names of the species?

The male species is called the male ailanthus webworm moth, and the female is called the female ailanthus webworm moth.

What would you call a baby ailanthus webworm moth?

What do they eat?

The Atteva aurea feeds on leaves, flowers, seeds, and nectar. They are invasive insects, meaning they slowly eat up the leaves of the residing plant, which becomes a food plant!

Are they dangerous?

The Attreva aurea is not dangerous but can be a minor pest in the backyard. They are good pollinators as they land on different flowers to extract the nectar, aiding pollination. But the ailanthus webworm moth is poisonous if eaten.

Would they make a good pet?

Moths do not make suitable pets as they are wild insects.

What is the ailanthus webworm moth's host plant?

The host plant of the Ailanthus webworm moth caterpillar is the Paradise tree (Simarouba glauca). However, the moth may also easily adapt to another plant, the tree of heaven (Ailanthus altissima), from which it derived its name too.
