- A constellation formed in the late 16th century by the Dutch cartographer and astronomer Petrus Plancius, who took some stars that Ptolemy in his Almagest had catalogued as lying outside Canis Major. These unformed stars can be seen, for example, on the southern half of Albrecht Dürer’s star chart of 1515 as two little groups, one group of six to the south of Lepus, from which the dove was formed, and another group of five between the hind legs of Canis Major which Plancius visualized as an olive branch.

A small constellation to the south of Crux, the Southern Cross. Musca was one of the 12 southern constellations introduced at the end of the 16th century by Pieter Dirkszoon Keyser and Frederick de Houtman from the stars they observed during the first Dutch expeditions to the East Indies. The constellation arose because the seafarers saw chameleons eating flies during their stopover on Madagascar, and in the sky the fly lies next to the constellation Chamaeleon. These new southern constellations were first depicted by their fellow Dutchman Petrus Plancius on his globe of 1598, but for some reason he left the fly unnamed. In de Houtman’s catalogue of 1603, completed after Keyser’s death, it is called De Vlieghe, Dutch for fly.
