The Bay Area is home to a surprising variety of butterflies, moths, and skippers; local artist and avid lepidopterist Liam O’Brien gets outside with his field journal whenever he can, to record them with his unusual mixture of drawing, painting, collage, and writing. A beautiful sunny day out in the oak savanna of Mount Diablo brought two rare species into view, and onto the pages of Liam’s notebook.
