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. Larvae feed on common agrimony (Agrimonia eupatoria), Agrimonia procera, bastard-agrimony (Aremonia agrimonoides), musk strawberry (Fragaria moschata), wild strawberry (Fragaria vesca), creamy strawberry (Fragaria viridis), water avens (Geum rivale), wood avens (Geum urbanum), European dewberry (Rubus caesius), Rubus dumetorum, European blackberry (Rubus fruticosus), raspberry (Rubus idaeus)...

About 10% of wildlife watchers report a Golden Pigmy sighting in Birmingham on a given day, based on 63 verified sightings from GBIF citizen-science data. It is the 151st most-seen of the 811 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Golden Pigmy is recorded against all the insects logged in Birmingham (63 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.
