Eilema bipartita is a species of moth in the family Erebidae, subfamily Arctiinae (commonly known as lichen‑bearing or “footmen” moths). The species was first described by the British entomologist Francis Walker in 1863.
Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Erebidae
- Subfamily: Arctiinae (Lithosiini)
- Genus: Eilema
- Species: E. bipartita
- Authority: (Walker, 1863)
Description
Members of the genus Eilema are typically small to medium‑sized moths with slender bodies and narrow forewings. While specific morphological details for E. bipartita are not extensively documented in readily available literature, the species is presumed to share the general characteristics of its congeners:
- Wingspan: Approximately 20–30 mm (typical for Eilema species).
- Forewings: Usually pale, often grayish‑white or yellowish, sometimes exhibiting subtle transverse markings; the epithet “bipartita” may refer to a distinctive two‑part coloration or pattern, though precise coloration for this species has not been definitively recorded.
- Hindwings: Typically paler than the forewings, matching the overall subdued coloration of the genus.
- Antennae: Filiform (thread‑like) in both sexes.
Distribution
Eilema bipartita is known from the Afrotropical region. Recorded occurrences include several West and Central African countries, notably:
- Cameroon
- Gabon
- Democratic Republic of the Congo
- Sierra Leone
The full extent of its range may be broader, but confirmed records are limited to these locales as documented in regional lepidopteran databases and museum collections.
Habitat and Ecology
The ecological habits of E. bipartita have not been specifically studied. However, as with other Eilema species, it is likely to inhabit forested environments where lichens and algae are abundant, providing food for the larvae. Adults are nocturnal and are attracted to light sources, a common behavior among many noctuid and erebid moths.
Conservation Status
No formal assessment of Eilema bipartita has been published by the International Union for Conservation of Nature (IUCN). Consequently, its conservation status is currently Data Deficient.
