These caterpillars are custom built with every conceivable
self-protection device imaginable. Bright, garish colors which are
like danger signs in nature saying "I taste awful" or
"I am loaded with poison; multiple stinging barbs which inflict
painful and persistent burning rashes (on humans anyway); false eyes
pointing in every direction to say " I see you, you can't
surprise me"; a head end that looks the same as the rear end so
there can be no potential surprise attack from behind; and specific to
the Limacodid caterpillars (who actually have no true legs, hence the
slug in their name), a sticky adhesive underside that makes them very
difficult to prise off their food plant. With that in mind, stinging
nettle caterpillars are often not hard to find. They don't conceal
themselves day or night and will often be in the most conspicuous of
locations. Basically, they have little to fear.
