description Chelostoma rapunculi Overview
Chelostoma rapunculi is a species of solitary bee native to Europe, belonging to the family Megachilidae. It is oligolectic, meaning it forages exclusively for pollen from bellflowers within the Campanulaceae family. Female bees construct their nests in pre-existing narrow cavities, such as beetle borings in dead wood or hollow plant stems, partitioning the tunnels into individual cells using leaf fragments and mud.
