Rickard’s Notes on LRGV Checkered-Skippers

Mike Rickard did his usual great job of making difficult species ID sensible today on Facebook, in this case distinguishing between Desert Checkered-skipper and White Checkered-skipper, which cause me no end of consternation when I visit the Lower Rio Grande Valley.  Here’s his analysis:

“A brief primer on some checkered skippers. Desert Checkered-Skippers have a white dot at the forewing tip that White Checkered-Skippers lack; Desert Checkered-Skippers also have a large white spot on the forewing that’s missing on the White Checkered-Skippers, and Desert Checkered-Skippers have a pair of black dots on the hindwing underside. Photos today at the National Butterfly Center.”

By comparison, these features are lacking on White Checkered-skipper

Thanks a million, Mike!
