Green Silver-lines Pseudoips prasinana
Wingspan 30-35 mm.
Another of the very few British green moths, this species is fairly common in wooded areas over much of England and Wales, less common in Scotland and Ireland.
Flying mainly in June and July, it is often attracted to artificial light.
The short, plump caterpillar feeds in August, mostly on oak (Quercus) and birch (Betula), but also on other deciduous trees.
