Tortricinae Mostly medium-sized or large moths with relatively broad forewings. In some species the costa is slightly excavated and the apex produced so when at rest with its wings folded the moth is somewhat bell-shaped. The pattern of the forewings is varied, but generally consists of a basal patch, an outwardly oblique central fascia and a subapical blotch which are darker than the ground colour; the latter is generally some shade of yellow, red-brown or fuscous. The adults of several species, notably in the genus Acleris, are polymorphic, over a hundred forms having been named within a single species. The majority, however, vary little. Many of the larvae are polyphagous, feeding on a wide range either of trees and bushes, or of herbaceous plants. Most feed in spun leaves, twisting them, this being the origin of the name 'Tortrix'. One or two species are minor pests on fruit-trees. There are 94 species in the subfamily which have been recorded in Britain, though several are rare adventives or of very doubtful authenticity; 71 have been found in Essex. The subfamily includes some of our most widespread and common moths. Pandemis corylana (Fabr.) Res., 1885-1980. Polyphagous on trees. Wdspd and c. 49 *Loughton, etc. (AT). P. cinnamomeana (Treits.)
