Description: Lady beetles [various species including convergent Hippodamia convergens Guerin-Meneville and spotted Coleomegills maculata fuscilabris (Musant)] are important predators of soft-bodied insects such as aphids. The adult stages are easily recognized by their convex bodies and distinctive coloration. The hard wing covers are often orange, yellow, or red with a pattern of dark spots. Adult convergent lady beetles are black with orange or red wing covers with 12 black spots (spots are sometimes indistinct). The pronotum has two converging lines and a white margin. The adult spotted lady beetle is bright red to pink with black spots on the wig covers and pronotum. Yellowish lady beetle eggs are laid in groups on plants infested with aphids. The lady beetle larvae is enlongated with a velvety black to blue body 1/3-inch long with orange spots and black spines. Adults can consume 50 aphids per day, while larvae kill 10 to 25 per day.
