Stinging caterpillar hairs Two general kinds Spicule hairs shatter into fragments. Tiny fragments cause mechanical injury Some have toxins incorporated into the hair Can cause urticaria without contact with the caterpillar Spine Hairs Stinger-like spikes Toxins present in a poison gland at base of hair
