Identificaciones de kairune

I don't normally chase down Cabbage Whites for a photo at this time of year, but they have been conspicuously absent (in Burnaby at least) for the last month.

Found this macrocystis washed ashore. Along the beach there was also Fucus and Ulva. My prof told me that macrocystis normally isn't found in Vancouver/the Burrard Inlet.

Drift specimen.
