35.0205 Dichomeris acuminatus (Staudinger, 1876)

Status and Distribution

A singleton was attracted to a MV light trap on the 28th September 2016 in Walditch, Dorset. In the moth trap were a few other migratory species suggesting it probably arrived as a genuine migrant from continental Europe. A second was found on the Isles of Scilly in September 2018 (D. Grundy) further supporting the suggestion this is a migrant species.

    In Europe the larva is thought to feed on various species of medick and clover, including Medicago sativa (Lucerne) and possibly also Trifolium repens and T. pratense (White and Red Clover). It is also believed to feed on Medicago x varia (Bastard Lucerne ).
