Musca is a small constellation in the Southern Hemisphere. It is best seen in May.

Musca was first introduced by Johann Bayer in 1603 when he published his star atlas Uranometria. It was formerly referred to as Musca Australis vel Indica or the "Southern or Indian Fly" to differentiate it from a now-obsolete constellation called the Northern Fly, or Musca Borealis.


There is no mythology associated with this constellation.
