However, some species may have a lifespan of up to 2 to 3 years. Unlike adult ladybugs which can be black, red, orange, yellow, or pink and marked with evident spots as a defensive mechanism to intimidate prey animals. They have unique hemispherical, convex, to oval-shaped bodies.
The larvae are protected by an odorous, noxious fluid that comes out of their joints when they are disturbed. The most common species of lady beetles used as biological control agents in home gardens, landscape, and agricultural fields are Coleomegilla maculate , Harmonia axyridis , Coccinella septempunctata , and Hippodamia convergens.
Ladybug larvae are not considered dirt eaters, but they feed on dozens of aphids and other soft-bodied garden pests such as mites, scale, thrips, flies, adelgids, and eggs of other insects. Surprisingly, they can even eat other ladybug eggs too.
Other subfamilies, such as the Epilachninae, are considered vegetarian ladybugs. They can feed on mushrooms and fungus. Still, some prefer eating leaves and can be pests to certain plants. Today, there are commercially produced ladybug larvae packaged in suitable conditions and ready for release into the desired environment.
Ladybug larvae can be quite delicate if not handled with care. Lady beetles must be held in the refrigerator until they are ready to be released. Customers are drawn to live lady beetles on display in stores, but beetles left out at room temperature quickly deteriorate. Lady beetles are also frequently dehydrated and need water, especially if they have been kept at standard room temperature for more than a few hours.
Before storing lady beetles in the refrigerator, storekeepers or gardeners should spray them with water in a squirt bottle, being careful not to let water puddle in containers. According to a study by the University of California, aphid regulation requires a large number of lady beetles. In this case, applications of about 1, lady beetles each, spaced a week apart, are needed for one large, heavily infested rose bush in the landscape. The majority of store-bought packets only contain enough lady beetles to treat one aphid-infested shrub or a few small plants.
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. Their coloring is likely a reminder to any animals that have tried to eat their kind before: "I taste awful.

Their markings tell predators: "Eat something else! I taste terrible. They may also play dead. Birds are ladybugs' main predators, but they also fall victim to frogs , wasps, spiders, and dragonflies. Ladybugs lay their eggs in clusters or rows on the underside of a leaf, usually where aphids have gathered. Larvae, which vary in shape and color based on species, emerge in a few days. Seven-spotted ladybug larvae are long, black, and spiky-looking with orange or yellow spots.
Some say they look like tiny alligators. Larvae grow quickly and shed their skin several times.
