Butterflies Along Alaska's Hiking Trails



  Phoebus Parnassian Butterfly
Parnassius phoebus

This butterfly was found on the side of the Skyscraper Mountain Ridge in Hatcher Pass. It was at about the 4000' level in alpine tundra vegetation, in mid August. It appears to be a female. Males tend to have less pigment on their wings. (A male found on Flattop Mt.) This species lives only in Alaska, Yukon, and British Colombia. It prefers arctic tundra and alpine areas. Host plant is Sedum rosea (King's Crown, rosewort) which grows in rocky, alpine areas. (See the flowers here.) Caterpillars overwinter, enter chrysalis stage in the spring, and adults emerge in the summer.
