Not a yellow jacket, but not sure what it is...
This bee was really going after it in this thistle. I couldn't get a shot of the head.
Nice find in the Poison Oak by Ken-ichi.
Weird pupa (or something else?) on a poison oak leaf...
I asked Ken-ichi if he had ever seen an Alameda Whipsnake along this trail, and he answered in the negative. A few seconds later he exclaimed "Whipsnake!" and I was finally able to see one of these beauties.
We tried this technique for several other species but it was not effective.
