Agriopis leucophaearia, the spring usher, is a moth of the family Geometridae. The species was first described by Michael Denis and Ignaz Schiffermüller in 1775. It is a Palearctic species found from Europe, Turkey and Regions of the Russian Federation: the Volga-Don, East Caucasus, the European Central Black Earth, Central European, European southern taiga, the Western Caucasus, Kaliningrad, Mid-Volzhsky., mainly in oak forests and in heathland with low-growing oaks.
The ground colour of the wings is usually whitish. The forewings are nuanced red brown at the base and the tip, with discontinuous black lines associated with areas streaked with black. The hindwings of the underside are stippled black. Some individuals may be more dark (brown and black stains) and there are named variants. See Prout (1912–16). The female is wingless. The male has a wingspan of 10–30 mm. The egg is long-oval, pointed at one end; light grass-green.
The rather stout larva is green with yellow lines and brown dorsal blotches Wikipedia →

Rare
Under 5% of wildlife watchers report a Spring Usher Moth sighting in London on a given day, based on 32 verified sightings from GBIF citizen-science data. It is the 673rd 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.
January
In that month about 20% of wildlife watchers report a Spring Usher Moth in London on a given day, against under 5% in March to November, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Spring Usher Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 5
Of the 5 cities where we can rate Spring Usher Moth sightings, London ranks 3rd at under 5%. The best odds are in Prague (Czechia, about 10%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Spring Usher Moth is recorded against all the insects logged in London (32 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.
