It was described by the English entomologist, Henry Tibbats Stainton in 1854 from a type specimen found in England.
This species was first described by Henry T. Stainton in 1854 and originally named Nepticular microtheriella. It was subsequently placed in the genus Stigmella. The female type specimen is held at the Natural History Museum, London.

Rare
Under 5% of wildlife watchers report a Hazel Leafminer Moth sighting in London on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 688th most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
November
In that month about 20% of wildlife watchers report a Hazel Leafminer Moth in London on a given day, against under 5% in January to September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hazel Leafminer Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 8
Of the 8 cities where we can rate Hazel Leafminer Moth sightings, London ranks 3rd at under 5%. The best odds are in Liverpool (United Kingdom, about 10%) and Auckland (New Zealand, under 5%).
Same genus: Stigmella
The closest relatives of the Hazel Leafminer Moth that you can see in London (genus Stigmella) are Golden Pigmy (about 10%) and Scarce Maple Pigmy (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Hazel Leafminer Moth is recorded against all the insects logged in London (27 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.
