Stigmella aurella is a moth of the family Nepticulidae found in Africa, Asia and Europe. It was first described by the Danish zoologist, Johan Christian Fabricius in 1775. The larvae are leaf miners. 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)...

Rare
Under 5% of wildlife watchers report a Golden Pigmy sighting in Brussels on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 260th most-seen of the 337 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
March and August
In those months about 10% of wildlife watchers report a Golden Pigmy in Brussels on a given day, against under 5% in April–July and September–February, the lowest months.
5th of 7
Of the 7 cities where we can rate Golden Pigmy sightings, Brussels ranks 5th at under 5%. The best odds are in Liverpool (United Kingdom, about 30%), Birmingham (United Kingdom, about 10%) and Manchester (United Kingdom, about 10%).
Same order: Lepidoptera
The closest relatives of the Golden Pigmy that you can see in Brussels (order Lepidoptera, Butterflies and Moths) are Speckled Wood (about 20%), Red Admiral (about 20%) and European Peacock Butterfly (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Golden Pigmy is recorded against all the insects logged in Brussels (7 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.
