Definition
Scoparia leucomela is a species of moth in the family Crambidae, belonging to the genus Scoparia.
Overview
The species was first described in the late‑19th century by the lepidopterist Edward Meyrick. It is known from the Australasian region, with confirmed records from New Zealand and parts of Australia (particularly the eastern states). As with other members of the genus, S. leucomela is a small nocturnal moth whose larvae are presumed to feed on mosses or detritus, although the precise host plants have not been definitively documented.
Etymology / Origin
The specific epithet leucomela is derived from Greek roots: leukos meaning “white” and melas meaning “black”. This naming likely refers to the contrasting light and dark markings observed on the wings of the adult moth.

Taxonomy:
- Order: Lepidoptera
- Family: Crambidae
- Subfamily: Scopariinae
- Genus: Scoparia
- Species: S. leucomela
-
Morphology:
- Wingspan: reported to be in the range of 18–22 mm (exact measurements vary among specimens).
- Forewings: predominantly pale or whitish with distinct darker (often blackish) markings or streaks that create a mottled appearance.
- Hindwings: generally lighter, translucent grayish‑white.
- Antennae, legs, and body are typical of Scoparia moths, exhibiting fine scaling and a slender form.

Life cycle:
- Adults are attracted to light and are typically observed on wing during the warmer months (spring to early autumn).
- Larval habits are not thoroughly documented; many Scoparia larvae feed on mosses, lichens, or decaying plant material.

Distribution & Habitat:
- Confirmed presence in New Zealand (both North and South Islands) and in Australian regions such as Queensland and New South Wales.
- Occupies forested and sub‑alpine habitats where suitable mossy substrates are available.
