I woke up covered in a painful rash. A caterpillar with toxic hairs was to blame.

• I live in Maine, where browntail moth caterpillars can be found. 
• The caterpillars have a toxin on their hairs that can cause painful and itchy rashes on humans. 
• I woke up covered in what I thought were bug bites, only to realize it was the caterpillar rash. 

When I woke up, all I could feel was my entire body itching. I'm allergic to bug bites, and my first thought was that a mosquito had snuck under the covers and attacked me.
