Peppermint Looper

When young, these Caterpillars are prettily striped. The green dorsal surface has broad dorsal and ventro-lateral stripes that are black and dotted with white. The sides are creamy yellow with a brown lateral stripe. The ventral surface is green. The brick-red head and tail segment adds to the striking appearance of the caterpillar.
The mature caterpillars have a number of colour forms. Most have a green dorsal surface and blue-green ventral surface, which are separated by a yellow lateral line, and have a light yellowish-green head with a speckled mauve crown. The various colour forms have additional yellow, brown and/or purple straight or wavy stripes.
