The bird-cherry ermine (Yponomeuta evonymella) is a species of moth in the family Yponomeutidae, the ermine moths. The wingspan of the moth ranges from 16 to 25 mm. The insect was first described in 1758 by the Swedish naturalist Carl Linnaeus who gave it the name Phalaena evonymella; it was later transferred to the genus Yponomeuta, becoming Yponomeuta evonymella. The moth can be found in almost the whole of Europe and the northern and eastern part of Asia.
The adult bird-cherry ermine is a distinctive moth with a wingspan of between 16 and 25 mm (0.6 and 1.0 in). The forewings are white with five longitudinal rows of small black spots. The hind wings are a smoky brown colour, with a dark edging. They are wider and shorter than the forewings. The fine, thread-like antennae reach two-thirds of the length of the wings. When the moths are resting, the wings are rolled and placed close to the body, so that the insect looks almost tubular. At the slightest disturbance, the moths skip away and skilfully drop to the ground.
This species may be found in almost the whole of Europe from the river lowlands to the deciduous forest border in alluvial... Wikipedia →

Rare
Under 5% of wildlife watchers report a Bird-Cherry Ermine sighting in Vienna on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 724th most-seen of the 1406 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.
July
In that month about 10% of wildlife watchers report a Bird-Cherry Ermine in Vienna on a given day, against under 5% in August to June, the lowest months. That is one of Vienna's wettest months, with about 90 mm of rain against 40 mm in February.
Between 10 pm and 1 am
Across all the parks we cover, that three-hour window holds the most Bird-Cherry Ermine sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is seen both by day and at night.
22nd of 25
Of the 25 cities where we can rate Bird-Cherry Ermine sightings, Vienna ranks 22nd at under 5%. The best odds are in Helsinki (Finland, about 20%), Liverpool (United Kingdom, about 20%) and Manchester (United Kingdom, about 10%).
GBIF citizen-science records
It is estimated from how often the Bird-Cherry Ermine is recorded against all the insects logged in Vienna (14 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.
