What is "synegia"

Synegia is a genus of moth in the family Geometridae. It was described by Achille Guenée in 1857.

Most species in the genus have pale yellow or brownish wings banded and speckled with reddish gray. Many species have the fasciae marked by black dots. The similar dots also occur at the disc and margins of most species, though the type species Synegia botydaria (Guenée, 1858) has no black markings at all. Some have more extensive black or brownish gray clouding, and this can vary within a species. The body is delicate, legs and abdomen in males often elongate. The male antennae can be filiform (thread-like) or bipectinate (feather-like).
