Browntail Moth

News:

The Browntail Moth (Euproctis chrysorrhoea) was accidentally brought to Massachusetts from its native Europe in 1897, and soon after spread to the rest of New England and also moved into New Brunswick and Nova Scotia. The ‘problem’ with this insect derives mostly from the fact that throughout its life cycle (and especially in the very hairy caterpillar stage), it is armed with defensive, barbed hairs which break off, and for many people exposed to the hairs, cause skin rashes, headaches, and even difficulty breathing. The caterpillars have a huge host range of plants that they feed upon.

The moths, which fly at night and are active in July and August (and are attracted to light), have a wingspread of about 1.5 inches (36-42 mm). The wings and midsection are solid white on both the male and the female.  The abdomen has brown on it, and the brown coloration extends along most of the upper surface of the abdomen in the male, whereas in the female, the top (upper surface) of the abdomen is white, but the tuft of brown hairs is much larger.
