ID pointers: A fairly distinctive all white moth, that has a slightly silky appearance to the upper-wing surfaces, with a chocolate-brown abdomen in the male and brownish – grey in the female. The female has a brown tuft at the tip of the abdomen. The male has heavily feathered antennae.
Distribution: (First record: 1882 at Willington ) – (Last record: 1 July 2025 at Long Eaton ) – Extremely rare and current status unknown, due to insufficient records. Most likely an immigrant.Harrison & Sterling – First recorded in 1882 larvae found at Willington and in 1902.
Between 2014 – 2024 there have been a further 8 records. One Draycott (2014) one Findern (2015) one Kings Newton (2020) one Ambergate (larvae) (2022); Sandiacre (2023) Thulston (Larvae) (2024); Sandiacre (2024) and Kings Newton (2024). It is mainly a coastal species and is rarely seen in inland counties. The possibility of larvae or eggs being carried from coastal sites, where the species is a pest on Sea Buckthorn, cannot be ruled out. One on 27/28th June 2025 & two on 1/7/2025 – Long Eaton both records from same recorder.
