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 Seattle on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 246th most-seen of the 428 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.
September
In that month about 10% of wildlife watchers report a Hazel Leafminer Moth in Seattle on a given day, against under 5% in October to August, the lowest months. That is one of Seattle's driest months, with about 60 mm of rain against 190 mm in November.
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.
7th of 8
Of the 8 cities where we can rate Hazel Leafminer Moth sightings, Seattle ranks 7th at under 5%. The best odds are in Liverpool (United Kingdom, about 10%), Auckland (New Zealand, under 5%) and London (United Kingdom, under 5%).
Same order: Lepidoptera
The closest relatives of the Hazel Leafminer Moth that you can see in Seattle (order Lepidoptera, Butterflies and Moths) are Small White (about 20%), Woodland Skipper (about 20%) and Western Tiger Swallowtail (about 20%), 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 Seattle (13 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.
