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.

Foodplant and Larval Feeding Signs
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 ).
Finding the Moth
As a migrant, it is most likely to be encountered at light along coastal and adjacent inland areas of southern Britain.
As a migrant to Britain the moth has only been noted, so far, in late September. In Europe it has been recorded in all months from March to October and occurs in France, Italy, Portugal, Spain and some of the western Mediterranean islands.
