The saddleback caterpillar is about an inch long, has a purplish-brown body with a green saddle shape on it's back, and has poisonous spines on four large projections (tubercles) and many smaller ones that stick out from the sides of its body. The poisonous spines are hollow and are connected to poison glands.
