Leaf Feeders

The Leaf crumpler larva is around an inch long, with a green-grey color with purple markings at each segment. The adult is a small moth with brown and white stripes along its wings. The caterpillars build web tubes on twigs which incorporate leaf fragments as they feed. The tube can be 1.5-2 inches long by the time the caterpillar is mature. Damage and nests are at their peak in July and August.

Greedy scale are small armored scales that create a conical shaped cover. As they grow and shed their old exoskeleton, it is incorporated into the wax that makes up the shield. Eventually this results in a characteristic off-center nipple or dot on the outer coating. There are often concurrent overlapping generations on plants
Also see Hickory (Carya) as many of the insects that feed on hickory will also feed on pecan.
