Not many garden pests feed on the leaves of citrus trees. There are two exceptions. The orange dog is often a pest of young citrus trees. As an adult, the species is a large black and yellow swallowtail butterfly. However, it is named for the larva, which is an ugly brown and white caterpillar which grows to a length of 1 1/2 to 2 inches. During the summer and early fall, these caterpillars may be quite destructive on young trees. You can pick caterpillars off young trees by hand.

Several kinds of grasshoppers and katydids feed on the leaves of citrus trees, but
usually are not important pests. These are difficult to control because they are so mobile. Generally their feeding does not damage trees to any great extent.
