Young apple and pear fruits may be fed upon by several species of relatively large, stout-bodied green caterpillars Fig. 1). Their dominant green color is relieved by dots, dashes, lines, and stripes of white, cream, or yellow. For more than a century now, these native insects have been known to commercial and amateur fruit growers as "green fruitworms".
