Description
Mylothris chloris is a medium‑sized butterfly with a wingspan typically ranging from 50 to 60 mm. The dorsal wing surfaces are predominantly white or pale yellow, marked with distinct black marginal borders and a series of greenish or yellowish bands that may appear as “dots” along the wing edges, giving rise to its common name. The ventral side is similar but often shows a more muted coloration. Sexual dimorphism is minimal; males and females are alike in overall patterning, though females may be slightly larger.
Distribution
The species is native to the Afrotropical region, with confirmed records in West and Central African countries, including Sierra Leone, Liberia, Ivory Coast, Ghana, Nigeria, Cameroon, Gabon, the Republic of the Congo, and the Democratic Republic of the Congo. It predominantly occurs at low to mid elevations, generally below 1,200 m.
Habitat
Mylothris chloris inhabits forest edges, secondary growth, open woodlands, and savanna‑forest ecotones. It prefers sunny clearings where host plants are abundant, but it can also be found in more shaded understory environments.
Biology and Ecology
- Life Cycle: Like other pierid butterflies, M. chloris undergoes complete metamorphosis (egg → larva → pupa → adult).
- Host Plants: Larvae feed primarily on mistletoe species within the family Loranthaceae, especially those of the genera Tapinanthus and Loranthus.
- Adult Diet: Adults nectar on a variety of flowering plants; they are frequently observed visiting small, open flowers in sunny habitats.
- Behavior: Adults are strong fliers, often patrolling sunny gaps and exhibiting a characteristic gliding flight interspersed with quick, erratic bouts. Males are territorial, defending perches near host plants, while females are more cryptic, focusing on oviposition.
Conservation Status
The International Union for Conservation of Nature (IUCN) has not evaluated Mylothris chloris as a separate species; consequently, its official global conservation status is currently unassessed. However, the species is considered relatively common within suitable habitats across its range and does not face any immediate, species‑specific threats identified in the literature. Habitat loss due to deforestation and agricultural expansion may affect local populations.
