The caterpillar for the Vine Sphinx Moth can be any of three color combinations: pink, pale green or lemony-green. Five pair of diagonal lines run along the sides of the body. It may or may not have black dots as well. The preferred food for this caterpillar is a grape leaf so vineyards are likely to consider this insect a pest.
This member of the Sphinx Moth family is large, like its relatives, making it easy to spot. They are very common in the Southeastern U.S. as well as the mountainous Southwest. Like most moths, they are attracted to lights at night and are most active in late summer as well as early spring.
