Coastal Leaf-Cutter Bee

Megachile maritima, the coastal leaf-cutter bee, is a solitary bee in the family Megachilidae that constructs nests from leaf pieces cut from plants using its mandibles, a behaviour characteristic of the entire genus. The species is native to western and northern Europe, with confirmed populations in Belgium, Denmark, and Luxembourg, inhabiting coastal sand dunes, sandy grassland, and inland sandy heathland where it nests in the ground in loose, well-drained sandy soil. Female Megachile maritima cut semicircular pieces from the leaves of various plants, particularly vetches, clovers, and other legumes, to line the individual brood cells she constructs within the nest burrow. Each cell is provisioned with a pollen and nectar paste before a single egg is laid and the cell sealed with additional leaf pieces. Males emerge first and patrol vegetation in search of females. The species is classified as Vulnerable by the IUCN, reflecting substantial population declines associated with the loss of open sandy habitats through coastal development, vegetation succession and scrub encroachment on dunes, reduction of foraging plant diversity through agricultural intensification, and general declines in wild bee populations across northwestern Europe driven by pesticide use and habitat loss.
