Lady beetles, with about 450 species in the US, are commonly known for their beneficial role in controlling aphids, scales, mites, and other pests. They vary in color and size, ranging from orange, yellow, pink, tan, and white, with black spots, to entirely black, brown, or grey. In contrast, the Mexican bean beetle, resembling ladybugs, is a pale-yellow to copper-brown pest with 16 black spots on its wing covers. It exclusively feeds on bean leaves and pods. The Colorado potato beetle, another look-alike, has ten alternating stripped bands of black and light yellow to tan on its wing covers and is a vegetarian that feeds on potatoes, peppers, eggplant, and tomatoes. The larvae of these insects also have distinct characteristics, with ladybug larvae being black with red, orange, or black stripes or markings, while Mexican bean beetle larvae are bright yellow with short spikes protruding throughout their body, and Colorado potato beetle larvae are salmon-pink with black spots along the side. The eggs of these insects are similar in shape and color, ranging from yellow to orange. Lady beetles lay eggs wherever there is food for the young larva to feed on, while Mexican bean beetles lay their eggs on the plant they are feeding on, and Colorado potato beetles lay their eggs in mass or small clusters on the underside of the leaves. Lady beetles are valuable allies in organic gardening and can be encouraged to stay by providing them with flowers that offer nectar and pollen. Conversely, Mexican bean beetles and Colorado potato beetles are pests that can be controlled through various methods such as handpicking and crop rotation.
