Welcome to featured Wiki of the Day where we read the summary of the featured Wikipedia article every day.
The featured article for Friday, 4 August 2023 is Coccinellidae.
Coccinellidae () is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds in Britain; "lady" refers to mother Mary. Entomologists prefer the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. They are sexually dimorphic; adult females are larger than males. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they are distasteful.
Most coccinellid species are carnivorous predators, preying on insects such as aphids and scale insects. They are also known to consume non-animal matter, including plants and fungi. They are promiscuous breeders, reproducing in spring and summer in temperate regions and during the wet season in tropical regions. Many species lay their eggs near colonies of prey, ensuring their larvae have an immediate food source. Like most insects, they develop from larva to pupa to adult. Temperate species hibernate and diapause during the winter; tropical species are dormant during the dry season. Coccinellids migrate between dormancy and breeding sites.
Since they prey on agricultural pests, most coccinellids are considered beneficial insects. Several species have been introduced outside their range as biological control agents, with varying degrees of success. Some species are pests themselves and can infest people's homes, particularly in winter. Invasive species like Harmonia axyridis pose a threat to native ones. Other threats to coccinellids include climate change and habitat destruction. These insects have played roles in folklore, religion and poetry, and are particularly popular in nursery rhymes.
