Synthyris alpina is a host plant for checkerspot butterfly (Euphydryas anicia), which consumes leaves and sequesters iridoid glycosides (K. M. L’Empereur and F. R. Stermitz 1990). Flowering in plants of S. alpina begins at the margins of melting snow banks. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
