Audea melanoplaga is a species of moth in the family Erebidae, subfamily Erebinae. It was first described by the entomologist George Hampson in the early 20th century (the original description is attributed to 1913).
Taxonomy

Description
The adult moth exhibits the typical noctuid body plan, with forewings that are generally brown to grayish‑brown, bearing distinct darker markings that give the species its epithet “melanoplaga” (from Greek melano “black” and plaga “patch” or “region”). The wingspan is reported to fall within the range of approximately 30–40 mm, although precise measurements vary among individual specimens and geographic populations. The hindwings are paler in comparison, often with subtle transverse lines.
Distribution and Habitat
Audea melanoplaga has been recorded across several regions of sub‑Saharan Africa. Documented occurrences include:
- East Africa: Kenya, Tanzania, Uganda
- Southern Africa: South Africa (particularly the KwaZulu‑Natal province), Mozambique, Malawi
The species inhabits savanna, woodland, and open forest environments, where larvae are presumed to feed on a variety of low‑lying herbaceous plants, a common trait within the genus. Adults are nocturnal and are attracted to light, a behavior used by entomologists to sample populations.
Life Cycle and Ecology
Specific details of the life cycle of A. melanoplaga are not extensively documented in the primary literature. General patterns for related Erebinae moths suggest:
- Eggs: Laid singly or in small clusters on host plants.
- Larvae (caterpillars): Likely polyphagous, feeding on low‑lying vegetation; coloration provides camouflage.
- Pupation: Occurs in a loose cocoon within leaf litter or soil.
- Adults: Flight period varies with locality but generally spans the warmer months; multiple generations per year are possible in tropical zones.
Conservation Status
The species has not been evaluated by the International Union for Conservation of Nature (IUCN). No specific threats have been recorded, and it is not known to be of particular conservation concern.
