Coccinellidae
Ladybugs appear as half-spheres, tiny, spotted, round or oval-shaped domes. They have short legs and antennae. Their distinctive spots and attractive colors are meant to make them unappealing to predators. Ladybugs can secrete a fluid from joints in their legs which gives them a foul taste. Their coloring is likely a reminder to any animals that have tried to eat their kind before: "I taste awful." A threatened ladybug may both play dead and secrete the unappetizing substance to protect itself.
Coccinellids are generally considered beneficial to gardeners, as they typically eat aphids, scale insects, mealybugs, and mites throughout the winter. As in many insects, ladybugs in temperate regions enter diapause during the winter, so they often are among the first insects to appear in the spring
