description:
Mason bees nests in all sorts of holes: from holes in wood or thick stems (hogwood or bramble), empty snailhouses, holes in a brick wall, even in a keyhole. This type of bee can be found everywhere, even in the citycenter.
Mason bees belong to the sub-family: Megachilinae, they transport the pollen not at the legs but between long hairs at the abdomen. Masonbees can be divided into Osmia or Hoplitis species. Sixteen mason bees are listed on the Red List (RL). * = no further details yet.
