Edwards' Beach Moth (Anarta edwardsii) is a small, powdery-grey moth with a forewing length of 32-38 mm. The hindwings are bright white, crossed by a distinctive wide dark grey or dull black marginal band. The forewing fringes are brown-grey and hindwing fringes white. Larvae are pale green with faint white-green patterning. Eggs and pupae are undescribed.
Edwards' Beach Moth was assessed as Endangered by the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) because of the small number of known population localities and habitat decline. It is listed as Endangered in Canada on Schedule 1 of the Species at Risk Act (SARA). In British Columbia, Edwards' Beach Moth is ranked S1 (Endangered) by the Conservation Data Centre and is on the provincial Red list. The B.C. Conservation Framework ranks Edwards' Beach Moth as a Priority 1 under goal 3 (maintain the diversity of native species and ecosystems).
Recovery is considered to be biologically and technically feasible.
Surveys from 1995 to 2007 confirmed Edwards' Beach Moth is extant at 6 sites1 in B.C.: 5 within the southern Georgia Strait on southern Vancouver Island and 1 near Tofino, on western Vancouver Island. Since 2008, additional sampling in suitable habitats has not recorded additional occupied sites. ...
The recovery (population and distribution) goal is to ensure the persistence of Edwards' Beach Moth at all extant sites (and any new sites) and maintain its current distribution within its range in British Columbia.
The recovery objectives are:
1. To secure protection for the known sites (and new sites) and habitats of Edwards' Beach Moth.
2. To assess and mitigate the extent of current threats to Edwards' Beach Moth
3. To address knowledge gaps (e.g., habitat requirements, host plant use, range in B.C., dispersal abilities) for Edwards' Beach Moth
