COSEWIC Assessment and Status Report on the White Flower Moth (Schinia bimatris) in Canada

Limiting Factors and Threats

Schinia bimatris appears to be restricted by the limited availability of suitable active sand dunes. Dune stabilization by vegetation overgrowth may further limit the range of S. bimatris. Furthermore, a shift from relatively moist conditions to higher temperatures and more arid conditions, an effect of global climate change, may be re-activating dunes but may also be creating unsuitable microhabitat conditions within these dunes. The food plant and specific habitat requirements of S. bimatris need to be established before the exact limiting factors for this species can be determined.
