Phyllonorycter tristrigella
In 3 days ~20% in a week ~30%
Phyllonorycter tristrigella is a moth of the family Gracillariidae. It is known from all of Europe, except the Iberian Peninsula and the Balkan Peninsula, east to the European part of Russia. It was also recorded from Japan, but this is a misidentification of Phyllonorycter laciniatae.
The wingspan is 7–9 mm (0.28–0.35 in). There are two generations per year with adults on wing in May and again in August. The larvae feed on Ulmus glabra, Ulmus x hollandica, Ulmus laevis and Ulmus minor, mining the leaves. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Elm Midget is recorded against all the insects logged in Liverpool (11 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.
