Interesting tidbit: Toupee caterpillars

The toupee or puss caterpillar, as it’s known in its larvae form, (it’s the southern flannel moth in its adult form), is regarded as one of the most venomous caterpillars in the U.S. The caterpillar’s sting produces an immediate intense burning pain followed by the appearance of a red grid-like pattern on the skin. Sometimes swollen or enlarged lymph nodes will follow. Other reactions to the sting include headache, fever, nausea, vomiting, tachycardia, low blood pressure, seizure, abdominal pain, muscle spasms, and convulsions. Some people react more severely to stings than others. More severe reactions require immediate medical attention.
