Yponomeuta padella (orchard ermine) is a lepidopteran from the family Yponomeutidae, the ermine moths. It is also known as the cherry ermine The wingspan ranges from 19 to 22 millimetres (3⁄4 to 7⁄8 in). The head is white. Forewings are light grey, sometimes more or less suffused with white, especially towards dorsum; four longitudinal series of few black dots, first not reaching middle, second beginning beyond extremity of first, lowest including 4-6 dots; some additional black dots before termen; cilia light grey. Hindwings are rather dark grey. The larva is greenish-grey; spots black; head black.
The flight time ranges from July to August. The moth is attracted to light. The larvae feed on Prunus spinosa, other Prunus spp., Crataegus. Yponomeuta padella is widespread in Europe and can be found in all biotopes where the food plants are found. In the former Soviet Union, it is widespread in the European part in the north up to the Saint Petersburg area. In the east it is distributed in Transcaucasia, southern Kazakhstan, and central Asia. The species was introduced into North America.

With luck
About 10% of wildlife watchers report a Cherry Ermine sighting in Copenhagen on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 204th most-seen of the 476 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.
May–June and August
In those months about 10% of wildlife watchers report a Cherry Ermine in Copenhagen on a given day, against under 5% in July and September–April, the lowest months.
Between 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Cherry Ermine sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 6 cities where we can rate Cherry Ermine sightings, Copenhagen ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Helsinki (Finland, about 10%) and Liverpool (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Cherry Ermine is recorded against all the insects logged in Copenhagen (16 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.
