Small Heath (Coenonympha pamphilus)
A small butterfly and pale in colour this is a species easily assumed to be some anonymous moth, or even overlooked entirely. However it is present in many grassland sites in our hills where the caterpillars feed on fine-leaved grasses such as Sheep's Fescue.
Image: underside - the upperside is a pale ochre with faint markings but when the butterfly lands it usually closes its wings showing the underside as here.
Flight period: .Almost continuously from May to October in two, rarely three, broods
