In 3 days ~10% in a week ~30%
Nothris verbascella, the Norfolk snout or clay groundling, is a moth of the family Gelechiidae. It was described by Michael Denis and Ignaz Schiffermüller in 1775. It is found in almost all of Europe, Transcaucasia, Asia Minor, the Near East and the Russian Far East. It had been considered extinct in Britain since 1971, but was rediscovered in Norfolk on 4 September 2024.
The wingspan is 17–21 mm. There are two generations per year with adults on wing from May to early October. The caterpillars feed on hoary mullein Verbascum pulverulentum and some other species of mullein. Wikipedia →

Rare
Under 5% of wildlife watchers report a Nothris verbascella sighting in Sierra de Guadarrama National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 325th most-seen of the 597 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.
June–July and October
In those months about 10% of wildlife watchers report a Nothris verbascella in Sierra de Guadarrama National Park on a given day, against under 5% in August–September and November–May, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Nothris verbascella sightings with a recorded time, and nearly all of them come between 6 pm and 6 am: it is mostly seen at night.
Only Sierra de Guadarrama National Park, in our data
Sierra de Guadarrama National Park is the only park on Wallace's Line with enough records to rate Nothris verbascella sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Nothris verbascella is recorded against all the insects logged in Sierra de Guadarrama National Park (11 verified sightings from 2019 to 2026), 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.
