We first saw this butterfly on Butterfly Day, and it is still hanging around. It's a Peck's Skipper, easier to identify than many skippers because it is smaller and it has some beautifully distinct wing patterns.
More on Peck's Skippers here.
We also saw a Question Mark on Wednesday afternoon on the Transco Trail, near a Red Admiral — hadn't seen one of those guys since late June. Too bad it wasn't around on Butterfly day.
