Laguna Mountain Skipper


UWG, through our collaboration The Butterfly Project with Moorpark College, researched the feasibility of captive rearing for the endangered Laguna Mountain Skipper. We then wrote a reintroduction plan for the species and a project-specific plan to collect skippers from Palomar Mountain, rear their offspring in captivity, and then release them on Laguna Mountain. That work is currently ongoig (2023).
