The Coccinellidae are within the superfamily Coccinelloidea, which in turn is part of the infraorder Cucujiformia, a group containing most of the plant-eating beetles. The ladybirds form the majority of the species in the Coccinelloidea; many of the rest are fungus-feeding beetles or scavengers.
The larvae and adults of some species of lady beetles (Coccinellidae) feed on aphids that are pests. Other lady beetles feed on scale insects, whitefly and mealybugs. [172] If normal food sources are scarce, they may feed on small caterpillars, young plant bugs, or honeydew and nectar. [173]
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
Besides removing the insects by hand or including trap plants to lure away bugs, you can bring in (native) ladybugs as well. A ladybug larva can eat 50 aphids a day. A ladybug larva can eat 50 ...
The dried body of the female insect is 14–26% carminic acid. [24] Steps in the cochineal harvest in Oaxaca, public mural by Arturo Garcia Bustos, Mexico . Workers collect the female cochineal insects from their host plants. [4] The insects are killed by immersion in hot water or by exposure to sunlight, steam, or the heat of an oven.
Larder beetles are infrequent household pests. [20] Adults and larvae feed on raw skins and hides.
