A small, obsolete constellation that was located just above Aries, the ram. The constellation originated with the German astronomer Jakob Bartsch who created it during the seventeenth century. Other astronomers label the constellation as Apis, the bee. Later atlases recognized the constellation as a fly, called Musca Borealis. The term borealis (northern) was added to distinguish the constellation from Musca Australis, the southern fly, which is located below the Crux, the southern cross. This constellation, whether it is called Vespa, Apis, or Musca Borealis is no longer recognized by astronomers and its stars have been given back to Aries.
