If you see one of these fuzzy little guys around your yard, don't touch! They may look fluffy and cute, but they're venomous, and they've been spotted around the Tampa Bay area!
This is the venomous puss caterpillar, and according to Wikipedia, you'll regret touching it.
The caterpillar is regarded as a dangerous insect because of its venomous spines. Exposure to the caterpillar's fur-like spines will lead to an immediate skin irritation characterized by a, "grid-like hemorrhagic papular eruption with severe radiating pain". The pain has been described by patients as similar to a broken bone or blunt force trauma. The reactions are sometimes localized to the affected area but are often very severe, radiating up a limb and causing burning, swelling, nausea, headache, abdominal distress, rashes, blisters, and sometimes chest pain, numbness, or difficulty breathing. Additionally, it is not unusual to find sweating from the welts or hives at the site of the sting.
Well, that sounds nice.
