Sean calls them the sparrows of the butterfly world, and those little brown skippers can be quite a difficult group of butterflies to identify. He plans on spending some time this year trying to photograph as many species of skippers as possible for identification keys. It’s also a good exercise for him to sharpen his own ID skills with them.
