The moth is a serious polyphagous forest pest in Europe and northern Asia which causes periodic serious outbreaks. Such outbreaks have been recorded during the last 500 years in Europe. For example, in Poland 6 outbreaks have been recorded during the period 1946-1995. The last outbreak in Europe was in 2003 in Germany and Poland.

Females lay up to 300 eggs in clusters of 20-100 on tree trunks. After hatching, the larvae stay together for a day or two, before dispersing by climbing up into the foliage or hang on silk threads and are carried to other trees by the wind. The adult moths have a wingspan of 4-5 cm. Females are larger than males and have more elongated wings. Most adults have white forewings with black connected wavy arches. Dark forms, sometimes completely black are also sometimes observed and during one outbreak around 50% of the moths were dark.

For example, in Poland 6 outbreaks have been recorded during the period 1946-1995. The last outbreak in Europe was in 2003 in Germany and Poland.
