Mexican Bean Beetles feed on plants, particularly legume crops like beans. They are deceptive, featuring a yellow to copper-brown shell with sixteen black spots. However, they damage crops.

Their life cycle begins as an egg, which hatches into a spiny, yellow-orange larva. The larval stage lasts for some weeks, during which the larvae feed and grow before pupating on the leaves they feed on. 

After another week or two, the adult beetles emerge and start the cycle again. Controlling their population is essential to avoid significant crop damage.
