Megachilidae refers to a family of solitary bees belonging to the order Hymenoptera. This family is commonly known as leaf-cutting bees or mason bees. They are named so due to their distinctive habit of cutting leaves or collecting resin to construct their nests. Megachilidae is one of the largest families of bees, comprising over 5,000 species distributed worldwide.
The members of Megachilidae are generally medium-sized, robust bees, known for their densely hairy bodies. They vary in coloration, including shades of metallic greens, blues, and dark browns. These bees are known for their important ecological role as efficient pollinators. The females have specialized structures on their abdomen known as scopa, which are used to carry a mass of pollen collected from flowers back to their nests.
Unlike social bees such as honeybees, members of Megachilidae are solitary in nature and do not form colonies or possess a caste system. They construct their nests in various locations, including preexisting cavities, hollow stems, or holes in wood. The females prepare each nest cell, lining it with cut leaves or resin before provisioning it with a mixture of pollen and nectar. They then lay a single egg and seal the chamber before moving onto the next cell.
Overall, Megachilidae are a diverse and fascinating family of bees known for their leaf-cutting behavior, solitary lifestyle, and efficient pollination services.
The word "Megachilidae" has its etymology rooted in Greek. It is composed of two Greek words: "mega" meaning "large" or "great", and "cheilos" meaning "lip" or "proboscis". The combination of these elements refers to the large or prominent mandibles (jaws) that are characteristic of this family of bees.
