Euphydryas chalcedona olancha
Euphydryas chalcedona olancha was named by W.G. Wright in 1905 with a Type Locality of Olancha Peak, which is on the Tulare/Inyo Co. border west of the town of Olancha that straddles Highway 395. What stands out about this subspecies (in comparison to those I know best - nom. chalcedona and hennei) are the large white/cream spots on the dorsal side. That trait can be seen in individuals found on the west side of Sherman Pass down to at least Ant Canyon. Up Sherman Pass Road at 5800' I've seen larvae on Keckiella parviflora. They usually fly from April into July. They are almost certainly distasteful to predators due to that Keckiella, and thus possibly a model for dark-form palla females to mimic. That's my pet theory, anyway.
