Caloptilia suberinella
(Tengström, 1848)
Caloptilia suberinella is a small in the , first described by Tengström in 1848. The has a Palearctic distribution across northern and central Europe, extending eastward through Russia to China, with a recent confirmed record from British Columbia in North America. Like other members of its , it likely has leaf-mining , though specific associations for this species remain undocumented. are and have been observed at ultraviolet light sources.

Identification
The small size (14–15 mm wingspan) and characteristics place this among the microlepidoptera. It can be distinguished from other Caloptilia species only through examination of or molecular analysis; external is insufficient for reliable species-level identification within this . The recent North record from British Columbia requires verification against similar Caloptilia species.

Habitat
Specific requirements are not documented. Based on the , likely associated with where larval leaf mining occurs.
Distribution
to Palearctic region: Netherlands, Sweden, Norway, Finland, Denmark, Germany, Switzerland, Poland, Latvia, Estonia, Ukraine, Russia, and China. Recently recorded from North America (British Columbia, Canada), representing either a natural range expansion or introduction. GBIF records also indicate presence in Alberta, Canada, and additional Russian localities (Altai Republic, Amur Oblast, Buryatia Republic).

Taxonomic history
Originally described as Gracilaria suberinella by Tengström in 1848, later transferred to Caloptilia. The has 80 observations recorded on iNaturalist as of the knowledge cutoff.
North American status
The British Columbia record represents a significant range extension. Whether this is established and reproducing, or represents transient individuals, requires further investigation. The presence in Alberta (per GBIF) suggests the may be more widespread in western Canada than initially recognized.
