Like the Square-Spotted Blue, this is a "complex" of entities in evolutionary ferment. However, along our transect there is no such complexity. All of our populations, from the Sierra foothills over the crest, feed on the Eriogonum nudum group of Wild Buckwheats and have very similar life histories - one brood in late spring-early summer, matching the blooming time of the host. Adults rarely stray more than a few feet from the host, although males do puddle. They mate on the host and roost on it for the night.
