Megachilidae is a family of bees known for their unique nesting habits. Unlike many other bees, they often use materials like plant resins, mud, or leaves to construct their nests. This family includes well-known species such as leafcutter bees and mason bees, which play essential roles in pollination. These bees are typically solitary, meaning they do not live in large colonies like honeybees. Instead, each female usually builds and provisions her own nest. Megachilidae bees are important for the ecosystem, as they help pollinate a variety of flowering plants, contributing to biodiversity and food production.
