Others feed on pollen and nectar from flowers. On the other hand, ladybugs from the Halyziini tribe feed on fungi that grow on the leaves of plants. An example of this is the Mexican bean beetle Epilachna varivestis, which feeds on members of the bean family. The adults and larvae of the Epilachinae subfamily feed on plants. In the first generation, after hibernating, all females are reproductive In the second generation, a few females enter a state of physiological inactivity known as diapause In the third and fourth generation, most females enter diapause. Some members of the family are bivoltine (only two generations per year) and in others four to five generations can be observed per year. Mating occurs primarily at aggregation sites, shortly before the beetles disperse after winter dormancy. Beetles overwinter as adults, often in aggregations under leaf litter, rocks, and bark, with some species often taking shelter in buildings and houses. Female beetles can lay 20 to 1,000 eggs over a period of one to three months, beginning in spring or early summer.Īfter the pupal stage, the adults emerge, mate, search for prey, and prepare for hibernation. The members of the Coccinellidae family are holometabolic, that is, they have four stages of development: egg, larva, pupa and adult. The family is made up of more than 5,000 species, distributed in seven subfamilies: Chilocorinae (Mulsant, 1846), Coccidulinae (Mulsant, 1846), Coccinellinae (Latreille, 1807), Epilachninae (Mulsant, 1846), Hyperaspidinae (Duverger, 1989), Scymninae (Mulsant, 1876) and Sticholotidinae (Weise, 1901). Later in the United States the name ladybug was adopted. The name ladybug or ladybird (in English), was first used in medieval England, perhaps because the beneficial predators of plagues were believed to be a gift from the Virgin Mary, the "Lady" or lady (in English). Many of them are used in biological pest control programs to minimize and control the populations of aphids, whiteflies, scale insects and mealybugs that do so much damage to crops in different agrosystems. Most of them shed small insects as well as mites although we also find species that feed on plants, fungi, pollen and flower nectar. The ladybugs or coccinellids (family Coccinellidae) are a group of beetles that comprise around 5,000 to 6,000 species characterized by vibrant colors with small spots or stripes in their elytra (hardened wings). 627 pp.Video: Characteristics of Insects Content Introduction and protozoans to arthropods.
