Colotis phisadia, the blue-spotted Arab, is a small butterfly of the family Pieridae, that is, the yellows and whites, which is found in Mauritania, Senegal, Mali, Nigeria, Niger, Chad, Sudan, Ethiopia, Kenya, Kuwait, Uganda, Arabia, the Near East and India.

Upperside of male forewing has a pale salmon-pink ground colour, this colour paler outwardly; base heavily irrorated (sprinkled) with bluish-grey scales that extend outwards and are merged with a black patch that occupies the apex of the cell and spreads along the discocellulars; terminal third of wing black with enclosed spots of the ground colour in interspaces 3, 4, 5 and 9, the spot in 4 sometimes absent, the inner edge of the black area emarginate at interspaces 2 and 4; the outer margin with a series of minute terminal specks of ground colour in the interspaces.

Hindwing: white, base heavily irrorated with bluish-grey scales that are extended downwards in a diffuse band parallel to the dorsum; terminal half of wing jet black.

In other specimens the ground colour on both forewings and hindwings is entirely white or pinkish orange.

Underside: as in the male, but the apical area of the forewing and the whole surface of the hindwing tinged more or less with ochraceous.
