In 3 days ~20% in a week ~30%
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 →

With luck
About 10% of wildlife watchers report an Oak Carl sighting in Helsinki on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 251st most-seen of the 838 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
August to November
In those months about 10% of wildlife watchers report an Oak Carl in Helsinki on a given day, against under 5% in December to July, 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.
Yes
Of the 4 cities where we can rate Oak Carl sightings, Helsinki has the highest daily chance: about 10%. Next come Berlin (Germany, under 5%) and London (United Kingdom, under 5%).
Same order: Lepidoptera
The closest relatives of the Oak Carl that you can see in Helsinki (order Lepidoptera, Butterflies and Moths) are Red Admiral (about 30%), Small Tortoiseshell (about 30%) and Green-Veined White (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Oak Carl is recorded against all the insects logged in Helsinki (22 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.
