Although the moths of this family are not too remarkable in appearance, their larvae are truly stunning. Referred to as either slug caterpillars (for obvious reasons) or stinging nettle caterpillars, I can assure you that the latter name is immensely appropriate. Touch their armory of spines and I can attest to at least 24 hours of intense burning.
