|The wet-season form in Nigeria and the dry season form in Uganda|
Precis pelarga has a wingspan reaching about 43–51 millimetres (1.7–2.0 in). The forewings are falcate. A clearer band crosses the forewings and hindwings. This band is orange white in the wet season, bluish white in the dry season (seasonal polymorphism). The basal area of the wings is brown, while the margins are blackish, with a series of small white spots. The undersides of the wings are variegated, with yellowish-brown cryptic colours, mimicking dead leaves. Larvae feed on Solenostemon and Coleus (Lamiaceae species).
Precis pelarga can be found in open forests and in savannah, at an elevation of about 0–1,350 metres (0–4,429 ft) above sea level.
