Ladybug:

Ladybugs, often mistaken for delicate, decorative beetles, are actually fierce ecological enforcers. Color ranges from red, orange, or yellow, dotted with black spots. They typically devour aphids, mites, and other soft-bodied pests that threaten crops and gardens. More than just pest controllers, ladybugs when threatened release a foul-smelling fluid from their joints—a reflexive defense that deters predators.
