November in the Bay Area means there will be California oak moths in the woodlands. There are a lot more of them this year than last year. This is good news for the birds and spiders that eat them. Silvery grey, about the size of a nickel, they are noticeable only when they flutter about. (They are camouflaged by the now silvery colored oak leaves.)
Where to See Oak Moths
If you are in the Monterey Bay area, the Elkhorn Slough Reserve is a good place to see California oak moths. The trails along the Long Valley, South Marsh and Five Fingers loops are home to oak woodland and forests. Wherever the woodlands are, you are sure to find oak moths. If you hike the South Marsh trail, stop by Hummingbird Island. It is a great place to see hummingbirds and sometimes, otters as well. Closer to the San Francisco peninsula, you will find oak moths in the Palo Alto Foothills and in the Windy Hill Open Space Preserve.
