A very rare species in the northern part of Belgium. Uncommon and more frequently observed in the south. The dark unicolorous forms are predominant.
The larva lives at first on the catkins and leaves of the host plant. Hibernates initially as an adult. Mates in December or January and eggs are laid in January or February.
Males die around December or January, while females live till February or even till early April.They come to light and are more frequently recorded at sugar and on flowers of Hedera.
The adults fly from early October till December and reappears after hibernation sometimes as early as January, but usually onwards from February till early April in smaller numbers.
The larva lives on Salix and other deciduous trees like Quercus, Prunus spinosa and Crataegus, later on different species of herbaceous plants like Rumex and Taraxacum.
