Called ladybugs in North America, they're known as lady beetles or ladybird beetles in Europe. Their distinctive spots and attractive colours are meant to make them unappealing to predators. They can also secrete a fluid from the joints in their legs which gives them a foul taste. Their colouring is likely a reminder to any animals that have tried them, "I taste awful." A threatened ladybug can also play dead..lol. Not all, but most ladybugs voraciously consume plant-eating insects, such as aphids, and in doing so they help to protect crops. Ladybugs lay hundreds of eggs in the colonies of aphids and other plant-eating pests. When they hatch, the ladybug larvae immediately begin to feed.
