The host plant of the bird-cherry ermine is the bird cherry. Because the caterpillars make an extensive weblike nest, they can eat a whole tree bare unhindered although it is quite possible that the trees can survive with reduced growth in the following growth seasons.
The flight time ranges from July up to August. The moth can be found in the whole of Europe and the northern and eastern part of Asia.
