Netted Carpet Eustroma reticulata
([Denis & Schiffermüller], 1775)
Wingspan 20-25 mm.
A very attractive species, which is restricted to one or two localities in the Lake District, where it inhabits shady locations, usually close to water.
The larvae feed on the foliage of touch-me-not (Impatiens noli-tangere), and the moth is only to be found in close proximity to the foodplant.
The adults fly in July and August.
