About Euclidia glyphica Linnaeus, 1758
This section provides a technical description and notes on variation of Euclidia glyphica. The forewing is pale grey suffused with pale brown, or uniformly pale brown. Shadings on the forewing are dark olive brown. The inner line is pale, oblique and waved, and is followed by a brown band. The outer line is whitish and vertically waved, and is preceded by a brown band; the inner edge of this brown band forms the median line. At the costa, the outer line is excurved and accompanied by pale scales on each side. The submarginal line is obscure, and is followed by a darker diffuse band that forms a black blotch on the costa. The hindwing is orange, with dark veins. The base and inner margin of the hindwing are fuscous. A blackish submarginal band is present, which is outwardly toothed at the costa and middle. A dark terminal shade runs upward along the veins. More uniformly dark brown specimens are classified as the aberration suffusa Spul., which is the common form in Britain. Aberration marginata Spul. has a whitish ochreous subterminal area. In aberration obsoleta Strand, the dark bands of the underside are absent. Aberration tristicula Schultz is much darker than the typical form.
