The wingspan is 11–15 mm. The thorax is crested. The forewings are triangular, yellow, more or less suffused with orange or ferruginous and faintly darker-strigulated. The basal patch is often darker and always followed by a pale yellow dorsal mark. The central and terminal fasciae are often darker or blackish-mixed, edged with leaden-metallic dots. The hindwings are blackish - grey, lighter anteriorly. The larva yellow-whitish; dorsal line darker; head yellow-brownish.
Adults are on wing from May to July. The larvae feed on ash (Fraxinus excelsior), Manchurian ash (Fraxinus mandshurica), privet (Ligustrum species) (including broad-leaf privet (Ligustrum lucidum)) and barberry (Berberis species).
It is found in Europe, China (Heilongjiang, Jilin, Shaanxi, Sichuan, Beijing, Shandong), South Korea, Japan, Russia (Siberia, Ussuri) and Asia Minor. Fabricius originally called the moth Pyralis conwagana from a specimen found in Oxford, England. Pyralis refers to an... Wikipedia →

With luck
About 10% of wildlife watchers report a Yellow-Spot Tortrix sighting in Copenhagen on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 170th most-seen of the 476 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.
June to August
In those months about 10% of wildlife watchers report a Yellow-Spot Tortrix in Copenhagen on a given day, against under 5% in September to May, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Yellow-Spot Tortrix sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Yes
Of the 5 cities where we can rate Yellow-Spot Tortrix sightings, Copenhagen has the highest daily chance: about 10%. Next come Liverpool (United Kingdom, about 10%) and Rotterdam [The Hague] (Netherlands, under 5%).
GBIF citizen-science records
It is estimated from how often the Yellow-Spot Tortrix is recorded against all the insects logged in Copenhagen (19 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.
