Insect families are groups of related insects that share common characteristics and traits. Each family is part of a larger classification system that includes orders, which group together similar insects. For example, the family Culicidae includes mosquitoes, while the family Formicidae consists of ants. Insects are classified into families based on features like body structure, behavior, and habitat. This classification helps scientists understand the diversity of insects and their roles in ecosystems. Families can contain many species, each adapted to different environments, showcasing the vast variety of life within the insect world.
