Cream-bordered Green Pea Earias clorana
Wingspan 16-20 mm.
A small but distinctive species, only likely to be confused with the micro Tortrix viridana, which however rests with a much 'flatter' aspect.
It is scattered locally throughout south-eastern England, with occasional records elsewhere, and inhabits fens, marshes and damp woodland.
Flying mainly in May and June, sometimes there is a second generation in August.
The larvae feed on various willows (Salix), including osier (S. viminalis).
