Musca Borealis, the northern fly:

A small, obsolete constellation that was located just above Aries, the ram. The origin of the constellation is uncertain, although it probably was not created earlier than the beginning of the seventeenth century. Early renditions of the constellation had it being either a bee, Apis, or as Vespa, the wasp. Later star 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. Musca Borealis is no longer recognized as a separate constellation, its stars having been incorporated into Aries. Musca Australis is now simply known as Musca.
