In 3 days ~10% in a week ~20%
Tischeria ekebladella is a moth of the family Tischeriidae. It is found in most of Europe and the Caucasus. The wingspan is 8–11 mm. The forewings are deep ochreous yellow, suffusedly irrorated with fuscous towards the costa posteriorly and apex. Hindwings rather dark grey. Closely resembles Tischeria dodonea. Certain identification requires examination of a genitalia preparation.
Adults are on wing from May to June depending on the location. The larvae feed on Castanea mollissima, C. sativa, Quercus cerris, Q. dalechampii, Q. faginea, Q. frainetto, Q. macranthera, Q. macrocarpa, Q. macrolepis, Q. pedunculiflora, Q. petraea, Q. pubescens, Q. robur, Q. rubra and Q. serrata × turneri. They mine the leaves of their host plant. Wikipedia →

Rare
Under 5% of wildlife watchers report an Oak Carl sighting in London on a given day, based on 21 verified sightings from GBIF citizen-science data. It is the 776th 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.
September and November
In those months about 10% of wildlife watchers report an Oak Carl in London on a given day, against under 5% in October and December–August, the lowest months.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Oak Carl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
3rd of 4
Of the 4 cities where we can rate Oak Carl sightings, London ranks 3rd at under 5%. The best odds are in Helsinki (Finland, about 10%) and Berlin (Germany, under 5%).
GBIF citizen-science records
It is estimated from how often the Oak Carl is recorded against all the insects logged in London (21 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.
