Setora fletcheri slug caterpillar

Photo of a maroon spiky Setora fletcheri slug caterpillar. The slug caterpillar's decoration is not just for show. At any sign of danger, each cluster of spines blooms into a bristly sphere. Glands at the base of the spines produce venom rich in histamines--liquid peril for any would-be attacker.
