I stood on this and am in considerable discomfort. I’m a bit worried that they are poisonous.

Stinging Slug Caterpillar

Stinging Slug Caterpillar

Dear James,
This is a Stinging Slug Caterpillar in the family Limacodidae, and it matches this image on iSpot that is only identified to the family level.  We have several images of this Stinging Slug Caterpillar in our archives and we believe it is
Latoia vivida.  According to this Taylor Francis Online article:  “Larvae of the moth Latoia vivida (family Limacodidae) have spiny tubercles which cause sharp pain and subsequent urticaria upon contact with human skin.  This study describes the sting’s clinical consequences and evaluates the effect of various pharmacological modifiers on the clinical response.”  We suggest that you refer to that article and consult a physician if your symptoms persist.
