The brown-forehead whitewater ( Cabera exanthemata ) is a butterfly ( moth ) from the family of the Spanner (Geometridae).
features
The brown-fronted whitewater reaches a wingspan of 30 to 35 millimeters. The moths have cream-white wings that are yellow-gray pollinated. There are three curved and serrated brownish yellow transverse lines on the forewings; there are two on the hind wings. The forehead below the antennae is brownish (name!).
The caterpillars are either light green with a fine, powdery pollination, or, more rarely, brown in color with dark spots on the back.

Occurrence
The east-west distribution of the brown-fronted whitefish is comparable to the similar species Cabera pusaria . The moths can be found from the Iberian Peninsula across Europe to the Amur region . In the north, the distribution area extends beyond the Arctic Circle , while the species is absent in the south in Asia Minor and some adjacent eastern areas. The brown-forehead whitewater can also be found in North America .
Way of life
The brown-fronted whitefly can be found on the edges of forests and meadows, in heaths , moors , gardens and parklands. The moths are nocturnal and are attracted to artificial light sources. They can be found at altitudes of 100 to 1,800 meters ( Alps ), but the main area of distribution is on the plain.
The forage plants include u. a .:
- Willows ( Salix spec.)
- White willow ( Salix alba )
- Purple willow ( Salix purpurea )
- Basket willow ( Salix viminalis )
- Ear willow ( Salix aurita )
- Aspen ( Populus tremula )
- Black poplar ( Populus nigra )
- Alder ( Alnus spec.)
- Gray alder ( Alnus incana )
- Black Alder ( Alnus glutinosa )
- Hazelnut ( Corylus spec.)
- Birch trees ( Betula spec.)
- Sand birch ( Betula pendula )
The pupa hibernates.
Flight and caterpillar times
The brown-fronted whitetot forms a generation a year that flies from the beginning of May to the end of August. The caterpillars can be found from June to September. Under favorable climatic conditions, a second generation can be observed in Germany from August to October ( Upper Rhine Plain , Neckar-Tauberland , Upper Swabia ).
