Ectropis
''Ectropis'' is a genus in the geometer moth family (Geometridae). They are mostly paleotropical, but also plentiful in Australia and extend into Asia. Only one species – or cryptic species complex – (the engrailed/small engrailed, ''E. bistortata''/''E. crepuscularia'') is found in Europe. There are about 100 known species in this genus. Systematics and taxonomy All junior synonyms of ''Ectropis'' use ''G. crepuscularia'' as type species, and thus, even though this large genus might warrant subgeneric division, no names are presently available. Apart from ''Tephrosia'', established by Jean Baptiste Boisduval in 1840, the synonyms are also junior homonyms and consequently completely invalid. One of them, ''Coenobita'', was proposed by Johannes von Nepomuk Franz Xaver Gistel in 1848. Gistl was unaware that Jacob Hübner had described the genus ''Ectropis'', but he knew of Boisduval's ''Tephrosia''. However, Gistl misread the name of the spider genus ''Theraphosa'' (es ...

The Engrailed
The engrailed and small engrailed (''Ectropis crepuscularia'') are moths of the family Geometridae found from the British Isles through central and eastern Europe to the Russian Far East and Kazakhstan. The western Mediterranean and Asia Minor and the Caucasus represent the southern limit of the distribution (with the Balkan countries). In the north, the distribution area ends at the Arctic Circle. It also occurs in North America. Debate exists as to whether they make up one species, or whether ''E. crepuscularia'' actually refers only to the small engrailed, with the engrailed proper being separable as ''E. bistortata''. The ground colour of the wings is buff or grey, variably marked with darker fascia and a pale postdiscal crossline. The darker markings are not usually as strong as in the rather similar willow beauty. Melanic forms occur fairly frequently. The wingspan is . One or two broods are produced each year. In the British Isles, the adults can be seen at any time be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hypomecis
''Hypomecis'' is a genus of moths in the family Geometridae first described by Jacob Hübner in 1821. Description Palpi oblique, reaching beyond the frons and fringed with hair below. Forewings with slightly crenulate (scalloped) cilia. Vein 3 from near angle of cell and veins 7 to 9 from near upper angle. Typically with vein 10 and 11 arise from cell. Hindwings with vein 3 from near angle of cell. Cilia crenulate. Ecology Most of them are patterned cryptically and when they sit on bark, the markings appear like patches of lichen. Studies have shown that they choose the site for resting with care so that the pattern of crypsis is enhanced. Selected species Species include: * '' Hypomecis adamata'' (Felder, 1874) * '' Hypomecis brevifasciata'' (Wileman, 1911) * '' Hypomecis buchholzaria'' (Lemmer, 1937) * '' Hypomecis ceylanicaria'' Nietner, 1861 * '' Hypomecis cineracea'' (Moore, 1888) * '' Hypomecis corticea'' (Bastelberger, 1911) * '' Hypomecis driophila'' Goldfinch, 1944 * ...
