Genus Anoplonyx

Anoplonyx

Globally there are around twelve species distributed across the palaearctic and nearctic regions. In Britain and Ireland there is only one species.

The genus Anoplonyx can be characterised within the Nematinae by the following features. In the forewing, the anal cell is divided by a wide restriction into separate basal and apical cells, vein 2m-cu meets cell 1Rs. The distance between the points where vein M and vein Rs+M meet vein R is clearly longer than the vein separating 1R1 from 1RS. The tarsal claws are simple with only a single tooth.

Larvae feed on the needles of species of larch.
