Synonyms and other taxonomic changes
Swammerdamia caesiella (Hübner, 1796)
Tinea caesiella Hübner, 1796
Swammerdamia heroldella of authors not Hübner, 1825 (misapplied name)
Tinea nubeculella Tengström, 1848
Tinea griseocapitella Stainton, 1851
Explanation of Names
Specific epithet caesiella is from Latin meaning "blue-grey." (1)
Duckworth, (1965) misapplied Swammerdamia heroldella Hübner, 1825 to Tinea caesiella Hübner, 1796. But Hübner (1825) replaced Tinea caesiella Hübner, 1816, not T. caesiella Hübner, 1796, with Swammerdamia heroldella. S. heroldella was later synonymized with Paraswammerdamia albicapitella (Scharfenberg, 1805), a species recorded from BC.
Size
Wingspan 9-13 mm.
Identification
Adult - greyish with a white head.
Range
Widespread in the Palearctic.
Season
Two broods a year in UK.

Birch (Betula).
Remarks
Possibly an introduced species, however, BOLD samples are in two BIN groups, one being strictly North American samples and the other European.
See Also
Other species in both Swammerdamia and Paraswammerdamia. It may that dissection is required to separate species.
