Charaxes imperialis, the imperial blue charaxes, is a butterfly in the family Nymphalidae. It is found in Guinea-Bissau, Guinea, Sierra Leone, Liberia, Ivory Coast, Ghana, Benin, Nigeria, Cameroon, Equatorial Guinea, the Republic of the Congo, the Central African Republic, the Democratic Republic of the Congo, Rwanda, Uganda, Tanzania and Zambia.[4]

Description

Ch. imperialis Btlr. male – forewing above with a straight blue transverse band, which starts somewhat behind the middle of the hindmargin, runs obliquely towards the apex, gradually narrowing anteriorly and broken up into spots; the band is 5 mm. in breadth at the hindmargin and only continuous to vein 2, then broken up into spots; the spots in cellules 3-5 contain white dots and those in cellules 6 and 7 are white, the one in cellule 7 placed nearer to the base than that in 6; the forewing is black and has in addition to these spots a white dot at the apex of the cell in cellule 4, a white dot before the middle of cellules 5 and 6 and small blue marginal spots. On the hindwing the blue band is continued to vein 2 with a breadth of about 7 mm. and placed almost exactly in the middle, covering the apex of the cell; blue submarginal spots and marginal streaks; tails short, about 3 mm. in length. On the under surface of the hindwing the black, distally light-margined transverse streaks of cellules 2-7 are placed in a nearly straight line. In the female the blue median band between vein 2 on the hindwing and vein 2 on the forewing is formed just as in the male, then follow in each cellule from 2-7 on the forewing two rounded, light yellow spots, the proximal one in cellule 4 placed at the apex of the cell; the marginal spots of both wings and the submarginal spots of the hindwing are yellowish. A rare species occurring from Sierra Leone to the Congo. [5]

Biology

The habitat consists of lowland to sub-montane forests.

The larvae probably feed on Sapindaceae species.
