Opogona omoscopa

(Meyrick, 1893)

Detritus Moth, Opogona Crown Borer

Opogona omoscopa is a small in the Tineidae with a wingspan of 18–22 mm. It has a broad native distribution spanning western Australia, New Zealand, southeast Asia, Africa, and islands of the Indian Ocean, and has been introduced to Europe, the United Kingdom, and the United States. The is attracted to ultraviolet light and has been documented at blacklighting events in California.

Identification

The can be identified to Tineidae by its small size and association with decaying organic matter. Distinctive features separating it from congeneric species are not documented in available sources. The 'Opogona crown borer' refers to larval damage patterns rather than .

Images

Appearance

Wingspan approximately 18–22 mm. Detailed coloration and pattern descriptions are not provided in available sources.

Habitat

Associated with environments containing decaying vegetation, rotting wood, and compost. Larvae develop in decomposing plant material and have been recorded from cultivated settings including pineapple plantations and ornamental plantings.

Distribution

Native to western Australia, New Zealand, southeast Asia, Africa (Ethiopia to South Africa), and islands of the Indian Ocean including Île Amsterdam. Introduced and established in the United States (California documented), Europe, and the United Kingdom.

Seasonality

have been recorded at blacklighting events in California during July and August, suggesting summer activity in temperate introduced ranges. Seasonal patterns in native range are not documented.

Diet

Larvae feed on decaying vegetation including rotting wood, cork, compost, rhubarb, gladioli corms, and pineapple roots. Documented plants include Persea sp. (avocado), Limonium sp., Cyclamen sp., Thuja sp., Fuchsia sp., Saccharum sp. (sugarcane), and Quercus suber (cork oak).

Host Associations

Persea sp. - larval Lauraceae
Limonium sp. - larval Plumbaginaceae
Cyclamen sp. - larval Myrsinaceae
Thuja sp. - larval Cupressaceae
Fuchsia sp. - larval Onagraceae
Saccharum sp. - larval Poaceae, sugarcane
Quercus suber - larval Fagaceae, cork oak
Ananas comosus - larval pineapple roots, inferred from source
Rheum rhabarbarum - larval rhubarb, inferred from source
Gladiolus - larval corms, inferred from source

Life Cycle

Complete with , larval, pupal, and stages. Larvae develop in decaying plant material and can damage living plants by feeding on roots and corms. Specific duration of developmental stages is not documented.

Behavior

are and attracted to ultraviolet light. Documented at blacklighting displays in California from approximately 9:15 to 11:00 p.m.

Ecological Role

Decomposer; larvae process decaying plant material. In agricultural and horticultural settings, can become a pest by damaging living plant roots and corms.

Human Relevance

Considered a pest of cultivated plants including strawberries, bird of paradise, and pineapple. The 'Opogona crown borer' refers to larval damage to plant crowns. Subject of entomological study and public education events such as Night at the Bohart Museum of Entomology.
