is 27–30 mm. and the length of the forewings is 13–16 mm. The ground colour of the forewings is deep yellow. There is a purple, variable in width median fascia extending from the costa. Antemedian and post median lines are reduced to purple dots. The irregular subterminal line is also reduced to a series of small dark dots. The hindwings are pale yellowish white, darker in the outer field. Very similar to ''
Xanthia icteritia'' but the median fascia is complete and ''togata'' is distinguished from the ''icteritia'' by the purple pigmentation of the head and shoulders. The moth flies from August to October depending on the location.
Ova
The pale-brown eggs are a flattened sphere, with relatively few ribs which are more prominent above the equator. They are laid in small rows and inserted behind the buds of
sallows (''Salix'' species) or
poplar (''Populus'' species). The moth overwinters as an egg.
Larva
Larva brownish grey, dotted with red and yellow; dorsal line pale, with darker edges, but obscure; spiracular line broadly pale. They feed at first in the catkins, which are usually the first to fall. The later
