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

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.

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″.

[5][6] The adults have working mandibles and feed on the pollen of a variety of flowers, especially those of sedges (Carex species).

[7] A single larva has been found amongst fungal hyphae in mixed beech, bilberry and oak leaf litter.
