The Original Specimen of the Mystery Bee (IMAGE) Canadian Museum of Nature Caption The « mystery » bee viewed from above (dorsal view). This is the holotype specimen of <em>Brachymelecta mucida</em>, presumed to have been collected in Nevada in the 1870s. It is now understood to be an aberrant specimen of <em>Brachymelecta californica</em>, the California digger-cuckoo bee. The unusual pale hairs on its abdomen were among the characteristics that led it to be classified separately from other related bees.
