Leptinotarsa decemlineata (Say)
The larva of the Colorado potato beetle is a red to orange soft grub about 1/2 inch (12 mm) long when mature. It has a black head, black legs and, when large, two rows of black spots on each side of the body. The larvae are often found either on the underside of leaves or at the top of the potato plant. The adult is a distinctive yellow and black striped beetle. Ten black stripes run along the length of the wing covers. The beetles are convex, about 1/8 inch (8 mm) long. The eggs, orange-yellow in color, can be found in clusters of about 20 on the undersides of leaves.
