Mugshot of a truly alien-looking critter
The saddleback caterpillar is one of the most common slug caterpillars and its sting is the severest, so watch out for this critter! Good that its distinct shape and markings make it hard to miss, though it is only about 1 inch long. Both ends of the caterpillar’s body are dark brown with brown “horns” that bear numerous spines. The middle of the body is green with a whitish margin and an oval spot in the middle, giving it the appearance of a saddle or blanket and therefore its name.
