While many butterfly species are common in Oregon, some are rare or endangered due to habitat loss and other factors. These species require special attention and conservation efforts to ensure their survival.
One such rare butterfly is the Oregon Silverspot (Glaucopsyche oregonensis). This butterfly is listed as endangered under the Endangered Species Act due to its limited range and small population size. It is found only in the Oregon coast range and is dependent on the presence of its host plant, the Oregon sunshine (Eriophyllum lanatum).
