Micropterix aureatella

Micropterix aureatella is a moth of the family Micropterigidae found in the Palearctic realm (from Europe to Japan), except for North Africa.

Taxonomy
The moth was first described from a specimen found in Carniola, present-day Slovenia, by the Austrian physician and naturalist Giovanni Antonio Scopoli in 1763. He named it Phalaena aureatella. Phalaena – a word used by Aristotle, meaning the rest of the moths; or possibly a devouring monster or whale, which may be derived from the destructive properties of clothes moths; or possibly from phallus an association by the Greeks of lepidoptera and semen which was supposed to attract moths; or paros i.e. a light and the attraction of moths to lights. The moth was later put in the genus Micropterix, which was raised by Jacob Hübner and the name comes from the small size of the adult; Mikros – ″little″ and pterux – ″a wing″. The specific name aureatella – golden from aureatus, referring to the three submetallic markings on the forewing.

Tinea merianella [Denis & Schiffermüller], 1775 is most probably a synonym of Micropterix aureatella, which is the only purple moth with three golden transverse fasciae within the federal territory of Vienna. The type of T. merianella was destroyed in the Hofburg fire in 1848 and it is thus hard to determine if the species is indeed a synonym.

Description
The wingspan is 9 - 11 mm. The head is yellowish and the base colour of the forewings is purple or bronze with two golden bands and an oval spot towards the wingtip. The adults have working mandibles and feed on the pollen of a variety of flowers, especially those of sedges (Carex species).

A single larva has been found amongst fungal hyphae in mixed beech, bilberry and oak leaf litter. The larvae are believed to feed on bilberry (Vaccinium species).
