Micropterix mansuetella is a species of moth belonging to the family Micropterigidae and can be found in Europe, in very wet woodlands, fens and carrs.

The forewings have a costal spot near the wingbase, a fascia before middle not reaching the dorsum, and the posterior half of wing is deeper golden, often more or less purple-tinged.

[4][5] M. mansuetella looks similar to M. tunbergella, but is less distinctly marked and has a black head, which distinguishes it from the other Micropterix.

The specific part of the name mansuetella, is a Latinized form of Greek, meaning tame; from the docile behaviour of the female when feeding on pollen.

[6] Micropterix mansuetella is distributed throughout northern, eastern, central and western Europe (including Great Britain and Ireland).
