Fen crest

Description

Brachmia inornatella, the fen crest, is a moth of the family Gelechiidae. It is found in large parts of Europe, except Ireland, Norway, Lithuania and most of southern Europe. The wingspan is 14–16 mm. Adults have been recorded on wing from May to August. The larvae feed on various grasses, including Phragmites australis. They probably feed internally in the stems. Brachmia is a genus of the twirler moth family (Gelechiidae). Among these, it is mostly placed in the subfamily Dichomeridinae. Other authors have used it as type genus of a distinct subfamily Brachmiinae. However, the "Brachmiinae" are considered an ill-defined assemblage of twirler moths whose relationships are not yet sufficiently determined, and the present genus is consequently sometimes placed incertae sedis within the Gelechiidae.
