brown-tail moth: meaning, definition, pronunciation and examples

The moths themselves are not directly dangerous, but their caterpillars are covered in tiny, barbed hairs that contain an irritant. These hairs can break off, become airborne, and cause a painful, itchy rash similar to poison ivy on contact with skin. They can also cause respiratory issues if inhaled.

They are native to Europe. They were accidentally introduced to North America in the late 19th century and are now established in parts of the northeastern United States, particularly in coastal regions of New England. In the UK, they are common in southern England.

The caterpillars (larvae) are the feeding stage. They are voracious defoliators, primarily feeding on the leaves of oak and fruit trees, but they can also attack other hardwood trees and shrubs like hawthorn, apple, and rose.

Avoid contact. Do not touch the caterpillars or their silken nests. In infested areas, wear long sleeves, pants, and gloves when gardening. Keep windows closed on windy days when hairs may be airborne. If you develop a rash, avoid scratching and consult a pharmacist or doctor for treatment options.

A white moth (Euproctis chrysorrhoea) whose caterpillar has a tuft of brown hairs at its tail end and is covered in irritating hairs that can cause skin rashes.
