Description
Oruza divisa is a species of moth within the family Erebidae. Members of the genus Oruza are typically small to medium‑sized nocturnal moths. While detailed morphological descriptions of O. divisa are scarce in widely accessible literature, the genus is generally characterized by:
- A modest wingspan, usually ranging from 15 to 22 mm.
- Forewings that are brown to grayish‑brown with subtle transverse markings or bands.
- Hindwings that are paler, often with a faint discal spot.
Distribution
Recorded occurrences of Oruza divisa are primarily in parts of South and Southeast Asia. Verified museum and biodiversity database records indicate presence in:
- India (including the Western Ghats)
- Sri Lanka
- Malaysia (Peninsular)
- Indonesia (Sumatra, Borneo)
Habitat
The species inhabits tropical and subtropical forested areas, including both primary and secondary woodlands. As a nocturnal moth, adults are attracted to light and are typically captured using light traps.
Life history and ecology
Specific information on the larval host plants, developmental stages, and behavior of O. divisa is limited. Like many Boletobiinae, larvae are presumed to feed on detritus, fungi, or low‑lying vegetation, but confirmation for this species is lacking.
Synonyms and taxonomic notes
No widely accepted synonyms have been recorded for Oruza divisa in major taxonomic catalogs. The species was originally described by Francis Walker in 1865 under the name Urecia divisa; it was later transferred to the genus Oruza.
