Mottled Duskywing are an endangered species in Canada under the Species at Risk Act. Our research fills in**critical knowledge gaps, required to achieve the overall recovery goal of the species in Ontario, which is to**ensure that existing threats to metapopulations and habitat are sufficiently mitigated to allow for the long-term**persistence and expansion of the species into unoccupied suitable habitats. We propose to use a closely-related**species with a similar life history, Wild Indigo Duskywing (Erynnis baptisiae), as a surrogate species to test**different captive rearing techniques and estimate survival. Our research objectives are to: (1) determine the**optimal conditions for Erynnis egg and larval development, (2) develop a captive rearing protocol, and (3) test**different treatments to overwinter individuals. Methods developed can also be used in the future for other**at-risk pollinator species. At the global scale, declines in pollinator populations and species diversity have**raised concerns regarding potential risks to global food security and economic development. The research**provides an excellent opportunity for academic and industry collaboration in Canada to realize the economic**benefits of protecting and recovering species at risk and economically important pollinators threatened by**climate change and other anthropogenic factors.**

斑纹黄翼是加拿大濒危物种法案中的濒危物种。我们的研究填补了**关键知识空白，这是实现安大略省物种整体恢复目标所必需的，即**确保对集合种群和栖息地的现有威胁得到充分缓解，以允许物种长期**持续并扩展到空置的合适栖息地。我们建议使用一种生活史相似的亲缘关系密切的物种--野生青黛作为替代物种，以测试**不同的圈养技术和估计生存。我们的研究目标是：(1)确定刺参鱼卵和幼体发育的最佳条件；(2)制定圈养饲养方案；(3)试验不同的越冬处理。开发的方法也可以在未来用于其他**濒危传粉者物种。在全球范围内，传粉者数量和物种多样性的下降**引起了人们对全球粮食安全和经济发展的潜在风险的担忧。这项研究**为加拿大的学术和行业合作提供了一个绝佳的机会，以实现保护和恢复受**气候变化和其他人为因素威胁的濒危物种和经济上重要的传粉者的经济**效益。
