A tiny wasp or bee on a Castilleja bloom.
This was growing as a bush at the base of a tree near a road and street sign. May be landscaping.
I believe this is a mosquito pupa. While searching a shallow, flooded meadow, I noticed these shrimp-like creatures wriggling somewhat tadpole like. Motile pupae! I guess baby mosquitoes never stop wriggling.
A metallic, indigo blue pentatomid.
This bright green, fruticose lichen was common on many trees.
A rather large, solitary ant.
Some kind of iris or iris relative?
I'm guessing Sugar Pine because of the very large cone.
A large gray slug. I think I read somewhere that the textured "thumbprint" mantle is a hallmark of the Arionidae.
radial fungus or mold on underside of a wet log
Possibly a Penstemon(?)
orange fungus on the ground. Possibly Aleuria sp?
I previously thought these were pine drops (Pterospora andromedea)
two butterflies enjoying lunch with a fly. I believe these to be a race of Callophrys gryneus, possibly subspecies nelsoni. Note the 3 spots and small tails on hind wing.
green algae in a slow-moving stream
Ranchman's tiger moth (Platyprepia virginalis).
Larva, with long white plume. Dead.
Youngsters in nests under a steel bridge.
