Wallace Falls State Park, Snohomish County

Wind, rain, low temperatures and no moths at the house again, last night, but the book has pinned down this photograph taken earlier in the week.

It is one of three described species of the genus Enchoria (Geometridae) which is endemic to the Pacific Coast. A day flying species from March to May - we saw it circling a sunlit gap in the Western Hemlock-Douglas Fir canopy, by Wallace River, and followed it to rest on a salmonberry leaf.
