description Osmia xanthomelana Overview

Osmia xanthomelana is a solitary species of mason bee native to Europe, first scientifically described by William Kirby in 1802. Unlike many bees that nest in pre-existing cavities or underground, this species is notable for constructing free-standing, exposed nest cells attached to rocks or stones. The female bee builds these protective structures using a mixture of chewed plant leaves, sand, and mineral particles. It is currently considered a scarce insect, heavily dependent on specific open habitats with sparse vegetation and access to its specialized building materials.
