Mexican Bean Beetle
One of the few plant-feeding ladybird beetles, recognized by its copper color and eight black spots per wing cover. Both adults and larvae skeletonize bean leaves.
Did You Know?
Unlike most ladybugs which are beneficial predators, the Mexican bean beetle is a destructive crop pest.
Willow Bean-Gall Sawfly
A tiny sawfly that induces distinctive bean-shaped galls on the leaves of various willow species. Each gall contains a single larva feeding on internal gall tissue.
Did You Know?
The gall-inducing chemicals secreted by the larva redirect the plant's growth to create a nutrient-rich chamber specifically for the larva's benefit.
