Did You Know…
This is a very adaptable butterfly with wide ranging habitat preferences and for these reasons our most frequently encountered alpine in the west (Brock, 2003). Males patrol all day to watch for females. Eggs are laid on living and dead grasses. Third- and fourth-stage caterpillars hibernate.
