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.

Animals This frog mysteriously re-evolved a full set of teeth. In the larval stage, ladybugs feed voraciously. In the two weeks it takes to become fully grown, a single larva can consume to aphids.
Ladybug larvae don't discriminate when feeding and will sometimes eat ladybug eggs, too. The newly hatched larva is in its first instar, a developmental stage that occurs between molts. It feeds until it grows too big for its cuticle, or soft shell, and then it molts. After molting, the larva is in the second instar. Ladybug larvae usually molt through four instars, or larval stages, before preparing to pupate.
The larva attaches itself to a leaf or other surface when it is ready to pupate, or metamorphose, into its adult form. In its pupal stage, the ladybug is usually yellow or orange with black markings.
The pupa remains still, attached to a leaf, throughout this stage. The ladybug's body undergoes a remarkable transformation, directed by special cells called histoblasts. They control a biochemical process through which the larval body is broken down and reformed into the adult ladybug. The pupal stage lasts between seven and 15 days. Newly emerged adults, or imagos, have soft exoskeletons, making them vulnerable to predators until their cuticles harden.
They appear pale and yellow when they emerge but soon develop the deep, bright colors for which ladybugs are known. Adult ladybugs feed on soft-bodied insects, just as their larvae do.
Adults overwinter, usually hibernating in aggregations. They mate soon after becoming active again in the spring. A garden plant prone to aphid infestations is a prime ladybug habitat. To familiarize yourself with the ladybug life cycle, visit this plant daily. Take your time examining the leaves, lifting them to observe the undersides, and you'll likely find a cluster of bright yellow eggs.
Within a few days, tiny ladybug larvae will hatch, and you'll find the odd-looking immature ladybugs on the prowl for aphids. However, a small proportion will eat plant matter, pollen and fungus. A larva is a juvenile form, which an animal species may take before developing into an adult.
They are mostly very different and distinct from the shape they will end up in. Examples would include caterpillars, which turn into butterflies and moths, and maggots, which become flies. All ladybird species start as an egg, which hatches into a larva. The larva then spends several weeks eating as much as they can, going through several instars growth forms where they shrug off their exoskeleton so they can become bigger and stronger.
Eventually, they will pupate and become an adult. Also read: How do Ladybugs Reproduce? From Egg, Larvae to Pupa. The purpose of an adult insect is to mate and produce young, thus continuing the cycle. The primary purpose of the larvae, by comparison, is to eat as much as physically possible. How well a ladybug larva gets fed can significantly alter its prospects as an adult, from whether it is likely to survive through the winter lean-time to whether any ladybugs of the opposite sex will find it attractive.
They have legs to walk their way to the next meal, but this can be a treacherous and time-consuming journey. To give them the best chance in life, therefore, the ladybug female will lay the eggs near what she thinks is a reliable food source. Many insect larvae will eat a completely different diet from their parents. This can be because the environments they live in are so different or that they require distinct things from their meals.
The larvae of the stag beetle Lucanus cervus , for example, live in rotten logs and will eat decaying wood. However, the adult form will survive on tree sap and spends more of its time out and about.
Ladybugs eat largely the same diet as a larva as they do as an adult.
