''Thera obeliscata'', the grey pine carpet, is a moth of the family Geometridae. It is found throughout North and Central Europe East across the Palearctic to Siberia, South to the Caucasus and Transcaucasia.In the Alps it rises to altitudes of over 1500 metres. The wingspan is 28–36 mm. Forewing reddish brown or fulvous, the distal edge of the median band not strongly indented, or with only one deep indentation (on the fold); pale subterminal line commonly obsolete, or if present, not strongly dentate. Hindwing rather more glossy and brownish than that of ''Thera variata'' , the discal dot generally altogether obsolete on the upperside, though expressed beneath. — ab. ''tristrigaria'' Donov. is an infrequent aberration with 3 unusually well developed, elongate interneural submarginal streaks between the 5th subcostal and 3rd radial veins. — ab. ''mediolucens'' Rossi, is a rather striking form in which the ground-colour is appreciably darkened while the median band remains fulvous, thus appearing lighter, or at least brighter, than the adjoining areas. — ab. ''obliterata'' B. White is almost unicolorous brown-black or black-brown Britain and occasionally in the mountains of Central Italy.〔Prout , L.B. 1912–16. Geometridae. In A. Seitz (ed.)
