The Southern Flannel Moth (Megalopyge opercularis)
Cute and oh so furry, am I right? These moths are widespread throughout the United States and commonly found on the East Coast stretching from New Jersey to Florida. Though they are completely harmless as adults, behind all that thick and lengthy, almost fur like hair, they have a sneaky little secret.
The larvae of this species is one of the most venomous caterpillars in the U.S. and are capable of delivering a sting so painful, it's described as a knife like feeling in your bones or getting bit by a snake. Some even say it resembles the sensation of amputation!
The caterpillar also goes by the name Puss Caterpillar, Asp Caterpillar, or Woolly Slug. They can be between 1-1.5 inches and have long hairs covering their entire body. These hairs act like stinging spines that carry toxic venom inside. As the caterpillar grows, they become curly and fluffier, making them look even more approachable and pet-able. But, the older they get, the more potent their venom becomes.
Now, before you panic, they are not actively out to attack, and their sting isn't lethal. But it is an extreme discomfort. A simple touch, just brushing past, is enough to cause the hairs to break off and inject their venom. Pain begins in minutes and increases quickly. It can spread all throughout the limb or affected area, then eventually the whole body. It is usually followed by redness and swelling as well. So, if you see the moths around, it is safe to assume there are many caterpillars nearby or waiting to be born.
Be safe and be smart, my friends.
