Description

Epilachna varivestis is a species of lady beetle that can be an agricultural pest. It is one of the few North American lady beetles that feed on plants rather than other insects. It is found throughout Mexico and the eastern United States, and is abundant in the wetter and more heavily irrigated areas west of the Rocky Mountains. It does not tolerate extremely dry areas. Adults are similar in appearance to other lady beetles, oval-shaped, approximately 6 to 7 millimeters long and bearing eight black spots on each elytron. Adult color is quite variable, ranging from bright red to rusty brown to golden yellow. The eggs are yellow, about 1.3 millimeters in length, and glued in clusters of up to 75 on the undersides of leaves. The larvae are usually yellow, spiny, and pill-shaped. Each is approximately 1.6 millimeters in length when first emerged, and grows to about centimeter length before pupation. Mexican bean beetle is present in the United States and found in most eastern states of the United States and Mexico. It can be found as far south as Guatemala and north into southern Canada or New England. The Mexican bean beetle is likely native to the southern plateau region of Mexico. Presence depends on the factors such as precipitation. It does not cause significant crop damage Guatemala and Mexico, but can be abundant in isolated areas of the western United States.
