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. A threatened ladybug may both play dead and secrete the unappetizing substance to protect itself.
