Found this hairy caterpillar on a garage near mango trees in Berbice, Guyana. The locals said it was very poisonous and said the hairs would cause swelling and a rash. They said those who have touched them need immediate medical attention. Not sure if it was true, but I still kept a safe distance. Could you identify what type of caterpillar this is? Thanks.

Flannel Moth Caterpillar

Dear TKozza,
The locals were wise to warn you about this stinging Flannel Moth Caterpillar in the genus
Megalopyge.  It is our understanding that the sting can be quite debilitating.

Greetings from Kyle, Texas!
This past weekend one of my kids found one of these asps crawling across our porch. It was a buff color and the largest I had ever seen. I captured it in a jar and then gave my kids (and the neighbor kids who were also there) a lesson that these are stinging caterpillars (in the glass jar we could actually see the stingers which are close to the feet) and never to be picked up or played with. We looked it up here at WTB of course, so everybody was well versed on these cute untouchables.
Then, this morning my youngest child who is four, came in saying that he’d found another one and sure enough he had found the darker one on our garage, very close to our rose bushes. On closer inspection, I found the orange one actually on the rose bushes. We decided to remove them and take some photos because of the color variations and also because they are very large…the jar lid they are occupying in the pics are three inches in diameter. To keep them and my kids safe, I put them in our compost pile where I put the other one from Saturday.
Thank you so much for your wonderful site!

Hi Brittany,
These are Southern Flannel Moth Caterpillars,
Megalopyge opercularis, and because they are stinging caterpillars, they are sometimes called Asps, especially in southern states.  They are also known as Puss Caterpillars according to BugGuide.

Stinging Asp

Handle the stinging Asp with care, or better yet, not at all.  The Asp or Puss Moth Caterpillar is the immature form of the Southern Flannel Moth, and it is one of North America’s stinging caterpillars.  The sting is reported to be quite painful.

Stinging Flannel Moth Caterpillar

Dear ??,
We have posted images of the stinging Flannel Moth Caterpillar,
Megalopyge lanata, several times in the past.  We are going to take this opportunity to create a new subcategory for Flannel Moth Caterpillars.  We love that your photo illustrates two different instars of this dangerous caterpillar.
