White Flower Moth – Héliotin blanc satiné
Extent and Area information
Threats (actual or imminent threats to populations or habitats)
The habitat requirements are not known for Canadian populations, but habitat loss through dune stabilization and changing dune microhabitat may be threats.
COSEWIC:Endangered (May 2005)
Status and Reasons for Designation
Alpha-numeric code: B1ab(iii)c(iv)+2 ab(iii)+(c)(iv)
Reasons for Designation: This moth is associated with dune habitats and is known from a small number of scattered sites in North America, with only one extant site in Canada. Most dune habitats in Canada appear to be too dry for this species. Dune habitat has undergone serious declines and the moth has likely declined as well.
Applicability of Criteria
Criterion A (Declining Total Population): Insufficient data.
Criterion B (Small Distribution, and Decline or Fluctuation): Meets B1ab(iii)c(iv)+2 ab(iii)+(c)(iv) for endangered. The extent of occurrence is much less than 5,000 km², the area of occupancy is much less than 500 km², with a population that is very likely severely fragmented and occurring at only one known location (reasonable confidence that it occurs at one, maybe two locations) with serious declines in suitable habitat and probable extreme fluctuations in the number of mature individuals, based on existence of such fluctuations in more southern populations of the species.
Criterion C (Small Total Population Size and Decline): Not applicable.
Criterion D (Very Small Population or Restricted Distribution): Meets D2 for threatened. It occupies and area of less than 20 km²and is known to occur at less than 5 locations.
Criterion E (Quantitative Analysis): Insufficient data.
