Are there poisonous frogs in New York?

The answer is most certainly yes. I was "stung" by one a couple days ago (early July) at East River Park while sitting under a tree. I felt some burning on my neck, reached into my shirt and pulled out an inch long caterpillar. It was white, with two long yellow hairs protruding from the front, as well as 2 long yellow, and 2 orange hairs protruding from the rear. It burned and itched immediately. Two days later, I currently still have tiny red bumps that look and feel similar to a poison ivy rash. Who knew?!?
