Astrognome A-Z of Constellations # 56 Musca

Musca the Fly- Southern Hemisphere 
Musca (Latin for "the fly") is a small constellation in the deep southern sky. It was one of 12 constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman, and it first appeared on a celestial globe 35 cm (14 in) in diameter published in 1597 (or 1598) in Amsterdam by Plancius and Jodocus Hondius.
The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. It was also known as Apis (Latin for "the bee") for 200 years.
Lacaille in 1776 renamed it to Musca Australis, the Southern Fly—Australis, to its then counterpart the now discarded constellation of Musca Borealis. The Australis part has now been discarded.
