Scarce Silver-lines Bena bicolorana
Wingspan 40-45 mm.
Possibly our most immaculate-looking moth, this is one of the few green species in Britain, and one of the brightest.
It is distributed widely in England and Wales, as far north as Yorkshire, being locally common in places. It inhabits woodland and parkland.
Flying from June to August, it regularly visits light.
The caterpillars feed on the leaves of oak (Quercus).
