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.
