''Eupithecia'' is a large genus of moths of the family Geometridae. There are hundreds of described species, found in all parts of the world (with 45 in the British Isles alone), and new species are discovered on a regular basis. ''Eupithecia'' species form the bulk of the group commonly known as pugs. They are generally small with muted colours and specific identification can be difficult. As a group they are easily identified by their narrow wings held flat at 90° to the body with the hindwings almost hidden behind the forewings. The larvae of many species feed on the flowers and seeds of their food plants rather than the foliage. Many species have a very specific food plant. Some Hawaiian ''Eupithecia'' as caterpillars are predators of other insects ('' E. orichloris'', '' E. staurophragma'', '' E. scoriodes''). They mimic twigs but when sensitive hairs on their backs are triggered, they quickly grab the insects touching them. The defensive behavior of snapping ...

Eupithecia Innotata
''Eupithecia innotata'', the angle-barred pug, is a moth of the family Geometridae. The species was first described by Johann Siegfried Hufnagel in 1767. It ranges from Spain in the west to western Siberia and Central Asia in the east. There are three forms found in the British Isles: * ''E. innotata sensu stricto'' (angle-barred pug) is found only on the east and south-east coasts * f. ''fraxinata'' (ash pug) is widely distributed * rare f. ''tamarisciata'' (tamarisk pug) The forewings are generally dark brown or grey with few distinguishing marks apart from a small white tornal spot which may not be present on the frequent melanic forms. The wingspan is 18–24 mm. Two broods are produced each year with the adults flying in May and June and again in August. Moths of the spring brood are usually darker in colour than the later specimens. The larva is bright yellow-brown with brown and greenish markings, most strikingly a variety of large, brown-green spots along the back. ...
