The mottled ermine (Yponomeuta evonymella) is an active lepidopteran on the day of the family Yponomeutidae, the ermine moths. The wingspan of the moth varies from 16 to 25 mm.
The host plant of the bird cherry ermine is the bird cherry. Because the caterpillars make an extensive nest like a spider web, they can eat a whole tree without hindrance, although it is quite possible that the trees can survive with reduced growth in the following growing seasons.
Flight time varies between July and August. The moth can be found throughout Europe and in the northern and eastern part of Asia.
Some members of the small 'Ermines' are difficult to separate visually, but this species is one of the easiest, since it has five rows of black spots on the tip of the wing.
Nightly, it flies during July and August, and it is attracted by the light.
The larvae feed on the leaves of the bird cherry (Prunus padus) and can appear in number of pests, completely eliminating the plant.
