Caterpillars are an enormous source of protein, many birds hunt caterpillars and some are large enough to be a complete meal for the day. Because mortality rates are high for Caterpillars, Butterflies will often lay hundreds of eggs to mitigate against large potential losses. Mites are small creatures — usually less than a millimeter in length.
Many creatures do not enter the pupa stage , they simply molt until they reach their adult form, these are called Nymphs and there are many of them that the Ladybug would predate on.
Examples include dragonflies, locusts and mayflies. Treat these the same as Caterpillars and are known as caterpillars. They come in many shapes and sizes and are prone to Ladybugs providing they can locate them as many moths and their caterpillar form are nocturnal or hideaway.

Often smaller than Aphids at around 1 mm in length, they can be found on the underside of leaves and in large numbers. Mealybugs are insects found in warmer climates and work operate similar to Aphids. Like Aphids, Mealybugs are often farmed by ants for their honeydew. If these are in the path of a Ladybug they are fair game. Along with the likes of Aphids and Whiteflies, Plant Lice are also considered part of a wider genre of Psyllidae, although this classification has since been broken down further it still encompasses the plant sap-sucking insects and bugs that Ladybugs would likely target.
Again these are plant feeders and part of the genre of Psyllidae. Thrips have lots of different names; thunder flies, thunder bugs, storm flies, thunder blights, storm bugs, corn fleas, corn flies, corn lice, freckle bugs, harvest bugs, and physopods. They have wings, but do not fly very well, preferring the clap and fling method of throwing their wings back and obtaining lift on the way down in order to get around — rather clumsily — but it works.
They are prevalent from the southern Canada Region through to central America so thriving in typically hot or tropical climates. They range from red and brown to white and black coloring.

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.
