Basking and nectaring
Air temperatures reached at least the high 60s in Bodega Bay today (7 March 2026). I started seeing butterflies zipping by in the morning, so I went out after lunch for a short walk and took a few photos.
California Tortoiseshells (Nymphalis californica) were the most common butterflies I saw today (photo above), but I also noticed quite a few Margined Whites (Pieris marginalis) and at least one Western Pine Elfin (Incisalia eryphon).
Many of the tortoiseshells were nectaring on willow catkins:

Shadowy Moon
Lucky that I looked at the Moon when I did early this morning. I checked a little bit later to try to see the Moon emerging from the shadow and it was completely fogged in!
This photo is from a little after 3:30 a.m. PST.

In the drift line
I didn't expect to find a Purple Sea Snail (Janthina umbilicata) tonight (2 March 2026), but I also thought there was potential. Ocean temperatures have been warm this winter and there was a lot of debris washed up on the beach tonight, so I kept the color purple in my search image and I happened to spot one individual.
The last time I recall Janthina being in our area was during the winter of 2024 (see post called "It's been a while" on 21 February 2024.)
It looks like there were several Janthina sightings in San Mateo County and Santa Cruz County in late February, so it's a good time to keep your eyes open for these beautiful pelagic snails. If you come across one, I'd love to hear about it!
