Mexican Bean Beetle (MBB), Epilachna varivestis Mulsant, (Fig 1) is an herbivorous ladybeetle (Coccinellidae) that feeds on legumes in North America. It is closely related to the squash ladybeetle, Epilachna borealis, which feeds primarily on cucurbits. MBB can cause significant defoliation damage to bean crops, particularly those in the genus Phaseolus (snap beans, lima beans, pole beans, etc.). For more information on general biology and pest management of MBB, see VCE Fact Sheet No. ENTO-51.
