Browntail Moth, Euproctis shrysorrhoea



Scientific Name: Euproctis shrysorrhoea
Common Name(s): Brown Tailed Moth

INVASIVE to MAINE                      Final Edit and Fact Checks Needed.

Research Summary
: David L.
My invasive species was difficult to research because there were not a lot of resources on this topic. This species is only found right now in Massachusetts, Maine and maritime Canada. One of the things that is interesting about the brown tailed moth is that the small hairs on the caterpillar, when in contact with human skin, will give you a wicked sting and rash.
