Description
The Plain Tiger is a medium-sized butterfly with a wingspan of about 7–8 cm. The body is black with many white spots. The wings are tawny the upper side being brighter and richer than the underside. The apical half of the fore wing is black with a white band. The hind wing has 3 black spots around the center. The hind wing has a thin border of black enclosing a series of semicircular white spots.
Background color and extent of white on the forewings varies somewhat across the wide range; see Systematics and taxonomy below.
The male Plain Tiger is smaller than the female, but more brightly colored. In addition, male danaines have a number of secondary sexual characteristics. In the case of the Plain Tiger, these are:
- The male has a pouch on the hindwing. This spot is white with a thick black border and bulges slightly. It is a cluster of specialised scent scales used to attract females.
- The males possess two brush-like organs which can be pushed out of the tip of the abdomen.

Famous quotes containing the word description:
“Everything to which we concede existence is a posit from the standpoint of a description of the theory-building process, and simultaneously real from the standpoint of the theory that is being built. Nor let us look down on the standpoint of the theory as make-believe; for we can never do better than occupy the standpoint of some theory or other, the best we can muster at the time.”
—Willard Van Orman Quine (b. 1908)
“An intentional object is given by a word or a phrase which gives a description under which.”
—Gertrude Elizabeth Margaret Anscombe (b. 1919)
“To give an accurate description of what has never occurred is not merely the proper occupation of the historian, but the inalienable privilege of any man of parts and culture.”
—Oscar Wilde (1854–1900)
