Taxonomy
- Kingdom: Animalia
- Phylum: Arthropoda
- Class: Insecta
- Order: Lepidoptera
- Family: Elachistidae
- Genus: Elachista
- Species: Elachista skulei
The species belongs to the genus Elachista, a large group of micro‑moths commonly referred to as grass‑miner moths.
Authority
Elachista skulei was formally described by the lepidopterist Lauri Kaila in 2003. The original description appears in a taxonomic revision of European Elachista species.
Distribution
The known range of E. skulei is confined to parts of northern and central Europe. Confirmed records include Sweden, Finland, and Norway. Distribution data are derived from national lepidopteran faunas and the Fauna Europaea database.
Habitat
Elachista species typically inhabit grassland and meadow ecosystems where host plants are abundant. While specific habitat preferences for E. skulei have not been extensively documented, it is presumed to occupy similar environments to congeners, favoring moist, herbaceous sites.
Life cycle and ecology
- Host plants: The larval stage of E. skulei is expected to be a leaf miner on grasses (Poaceae), a habit characteristic of most Elachista species. However, the precise host plant species for this moth have not been published.
- Phenology: Adults are recorded on the wing in late June and early July, aligning with the flight periods of related Elachista taxa in the region.
Morphology
Adults are small moths with a wingspan of approximately 8–10 mm. The forewings are generally narrow and display a pattern of silvery‑white and brown scales, typical of the genus. Detailed morphological characters used to separate E. skulei from closely related species are provided in Kaila (2003), including genitalia structure.
Conservation status
There is currently no specific assessment of E. skulei on the IUCN Red List. Its conservation status has not been evaluated at a European level, and the species is not listed in national threatened‑species registers.
