Erechthias minuscula
(Walsingham, 1897)
Caribbean Scavenger Moth, erechthias clothes moth
Erechthias minuscula is a small in the , first described by Lord Walsingham in 1897. It has a remarkably broad geographic distribution spanning tropical and subtropical regions across multiple continents and oceanic islands. The is known to utilize a wide variety of materials as food sources, including living plants, fruits, and decaying vegetation.

Identification
The extremely small size ( 3.5–4 mm) distinguishes this from most other . Definitive identification requires examination of or other microscopic features not described in general sources. It may be confused with other small , particularly other Erechthias species, but specific distinguishing characters are not documented.

Appearance
A small with length of 3.5–4 mm. Specific pattern, coloration, and body details are not documented in available sources.
Habitat
Found in tropical and subtropical environments across a wide range of islands and continental regions. Specific microhabitat preferences are not documented, though the is associated with areas where its diverse food sources occur.
Distribution
Recorded from Africa, Sri Lanka, Java, Australia, the Caroline Islands, Fiji, Samoa, the Marquesas, the West Indies, Hawaii, Florida, and the Galápagos Islands. The shows a disjunct distribution pattern across the Indo-Pacific, Australasia, and the Caribbean/Hawaiian region, suggesting human-mediated to some areas.
Diet
Recorded feeding on diverse materials including: Acacia koa, Acacia koaia, banana, Calotropis, Cassia, eggplant, fig, , palms, Pandanus, papaya, pineapple, Pipturus, Sapindus oahuensis, Sicana odorifera, and old tamarind pods. The breadth of recorded suggests opportunistic feeding on available plant material rather than strict specialization.

Ecological Role
Has been observed feeding on decaying material and living plant tissues across diverse plant , potentially contributing to through decomposition. The broad range suggests a ecological role rather than specialized .
Human Relevance
Considered a due to recorded feeding on economically important including banana, eggplant, fig, papaya, and pineapple. The "erechthias " suggests potential association with stored products or fabrics, though this is not explicitly documented in feeding records. Its widespread distribution across oceanic islands and distant regions indicates human-mediated , likely through trade in materials.

Taxonomic history
Originally described as Ereunetis minuscula by Walsingham in 1897, later transferred to Erechthias.
Dispersal mechanism
The disjunct global distribution across multiple oceanic island systems and continental regions strongly suggests human-mediated transport, likely through movement of materials, rather than natural .
