description Megachile centuncularis Overview

Megachile centuncularis, commonly known as the patchwork leafcutter bee, is a solitary bee species widely distributed across Europe. Females use their mandibles to cut neat, circular pieces from leaves, including those of roses, to construct and line their individual nest cells. As a member of the family Megachilidae, this species does not form hives or produce honey, but it is an important pollinator for various wildflowers and garden plants.

help Megachile centuncularis FAQ

Does Megachile centuncularis damage roses when it cuts the leaves?

Females often cut neat circles or semicircles from rose leaves, but the cosmetic damage is usually minor and does not kill a healthy plant. The pieces become partitions and wrappers for individual brood cells.

Where does the patchwork leafcutter bee make its nest?

It uses existing cavities in hollow stems, dead wood, walls, soil, and bee hotels rather than excavating a large hive. Each leaf-lined cell receives a pollen provision and one egg.

Is the patchwork leafcutter bee social or aggressive?

Megachile centuncularis is solitary, so each female builds and provisions her own nest. Females possess a sting but are not defending a communal honey store, making them unlikely to sting unless handled.

How can Megachile centuncularis be distinguished while carrying pollen?

Female leafcutter bees carry pollen on a brush of hairs beneath the abdomen rather than in baskets on the hind legs. In Megachile centuncularis, that orange pollen-laden underside can be conspicuous as the bee visits flowers.
