Mylothris continua is a species of butterfly belonging to the family Pieridae, which includes the whites and yellows. It is an Afrotropical species, primarily found in the forests of West and Central Africa.
Description
Mylothris continua is a medium-sized butterfly, typically displaying a wingspan of 45–55 mm. The upper surfaces of its wings are predominantly white, with the forewings featuring a distinct black apical (tip) patch. The hindwings are also white, sometimes exhibiting a subtle cream or yellowish tint, particularly on the underside. The underside of the hindwing may also show faint dark markings along the veins or disc. Sexual dimorphism is generally minimal, though females might be slightly larger than males.
Distribution and Habitat
This species is widely distributed across West and Central Africa. Its range extends from Sierra Leone and Liberia in the west, through countries such as Ivory Coast, Ghana, Togo, Nigeria, Cameroon, Gabon, Equatorial Guinea (including Bioko island), Congo, Central African Republic, and the Democratic Republic of Congo, reaching as far east as western Uganda. Mylothris continua primarily inhabits primary lowland forests and forest margins, where adults are often observed flying in the understory or along forest tracks.
Taxonomy and Subspecies
Mylothris continua is part of the genus Mylothris, which encompasses numerous species of African butterflies often referred to as "dotted border" or "African white" butterflies. Several subspecies have been recognized, reflecting geographical variations across its broad range. Notable subspecies include:
- Mylothris continua continua (Nominate subspecies, found in various parts of West and Central Africa)
- Mylothris continua katangae (Found in southeastern Democratic Republic of Congo)
- Mylothris continua congoana (Found in regions like Congo, Gabon) Other subspecies, such as ruandana and montana, may also be recognized depending on the specific taxonomic authority.
Ecology
Like other species within the genus Mylothris, the larvae of M. continua are believed to feed on plants from the family Loranthaceae (mistletoes), although specific host plant records for this particular species are not always explicitly documented. Adult butterflies are diurnal, feeding on nectar from various flowering plants and exhibiting a relatively slow, fluttering flight characteristic of many white butterflies.
