However, the Bugman of Mt. Washington on What's That Bug? admits in post after post, identifying the species of Skipper is a job best left to the Skipper experts, because there are just too many similar species.

There must have been dozens of these small (inch-long), orange & brown butterflies fluttering around the dandelions toward the bottom of the Corralitas Public Staircase.
In general, this summer, I've noticed way more butterflies of all species than ever before.
