The wingspan is 6–7 millimetres (0.24–0.28 in). The head is ferruginous to orange. Antennal eyecaps ochreous-whitish. Forewings shining copper gold; a shining pale golden fascia beyond middle, preceded by a purplish or dark purple-fuscous fascia, apical area beyond this dark purple to fuscous. Hindwings rather dark grey. Adults are on wing in May and later in the summer.
Ovum Eggs are laid on either side of a leaf. Larva Larvae are amber yellow with a greenish-brown gut and a yellow-brown head. The mine is a long sinuous gallery which gradually widens and the frass is dispersed.

GBIF citizen-science records
It is estimated from how often the Golden Pigmy is recorded against all the insects logged in Manchester (36 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
