Definition
Scopula adenensis is a species of moth in the family Geometridae, subfamily Sterrhinae.
Overview
The species belongs to the genus Scopula, which comprises a large group of geometer moths known as “wave” moths. Scopula adenensis was formally described in the scientific literature in the late 20th century. It is recorded from the Arabian Peninsula, with confirmed occurrences in the vicinity of Aden (present‑day Yemen) and surrounding arid coastal regions. As a member of the Sterrhinae, it is nocturnal and attracted to light, typical of many geometer moths.
Etymology/Origin
The specific epithet “adenensis” is derived from the locality name Aden, indicating the region where the type specimen was collected. The genus name Scopula originates from Latin “scopula,” meaning “small broom” or “brush,” a reference historically applied to the wing‑scale texture of related moths.
Characteristics

Taxonomy:
- Order: Lepidoptera
- Family: Geometridae
- Subfamily: Sterrhinae
- Tribe: Scopulini
- Genus: Scopula
- Species: S. adenensis
-
Morphology: Detailed morphological descriptions are limited in publicly available sources. Generally, Scopula species exhibit slender bodies, broad wings with delicate transverse lines, and a wingspan ranging from 18 mm to 30 mm. Specific wing pattern, coloration, and genitalia structure for S. adenensis are documented in the original species description but are not reproduced here.
-
Habitat and Distribution: The species inhabits dry, subtropical to arid environments along the southern Arabian coast. Records are primarily from Yemen, with occasional reports from neighboring countries, though the full extent of its range requires further field verification.
-
Life Cycle: Like other geometer moths, the larvae (inchworms) are expected to feed on low‑lying herbaceous plants, but host‑plant associations for S. adenensis have not been conclusively identified.
