What is a "brown-tail moth"?

A brown-tail moth is a moth species notorious for its irritating hairs and potential health hazards. Found primarily in Europe and North America, the brown-tail moth has distinctive white wings with a brownish tail on the males. The larvae of the moth are covered in long, barbed hairs that can cause skin irritation and allergic reactions in humans upon contact. The hairs can become airborne, leading to respiratory issues if inhaled. Infestations of the brown-tail moth can pose a challenge to forestry, horticulture, and public health.
