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.
Horn-headed Rove Beetle
A small rove beetle in which males bear three horn-like projections on the head, used in combat for burrow ownership. It is a specialist of sandy riparian habitats near rivers and lakes.
Did You Know?
Males with larger horns win more contests for burrow ownership, but hornless 'sneaker' males can also mate by entering burrows when the resident male is absent.
