Distribution and habitat
This species can be found in Guinea, Sierra Leone, Liberia, Ivory Coast, south-western Ghana, Nigeria, Cameroon, Gabon, the Republic of the Congo, the Central African Republic, the Democratic Republic of the Congo and western Uganda.[2][5][6] The habitat consists of wet primary forests.
Description
Charaxes hadrianus has a wingspan reaching about 90 millimetres (3.5 in). The upperside of the forewings is white, with a brown basal area and a black apical part showing several white spots. The underside of the forewings is grey, with a large black eyespot. The upperside of the hindwings is white, with black outer margins. The underside of the hindwings is crossed vertically midway by a red band, with a row of small black spot on the outer margin.[7]
Description in Seitz
Hadrianus Group. This group is only represented by a single species of characteristic appearance. Hindwing above and both wings beneath with white ground-colour. The black transverse streaks in the basal part of the under surface are very fine and in part indistinct or entirely suppressed; in cellule lb of the forewing near the hinder angle a large, deep black spot. The tails of the hindwing are obtuse, the one at vein 2 about 2 mm., that at vein 4 nearly 5 mm. in length. Sexes alike in colour and markings. Ch. hadrianus Ward Forewing at the base red-brown nearly to vein 3, then black with a white median band, at the hindmargin about 15 mm. in breadth, but rapidly narrowing anteriorly and terminating at vein 5, with two small white discal spots in cellules 5 and 6, white submarginal spots in 2-6 and a white marginal spot in lb. Hindwing above narrowly red-brown at the base, with black submarginal and marginal streaks at the distal margin. Beneath the hindwing has in the middle a thick black transverse line, distally accompanied by a deeply dentate red-brown transverse band; this transverse band shows through above. A beautiful but rare species, occurring from the Niger to the Congo.[8]
Biology
The larvae feed on Ourateaspecies (Ouratea reticulata)[2] and Ochna species.
