I believe these are tiny scale-like pupae of a Whitefly (Aleyrodidae, Sternorrhyncha, Hemiptera) on the underside of a leaf of Coast Live Oak (Quercus agrifolia, Fagaceae) in the woods today. Or are they larvae? They are tiny, about 260 pixels long in this 1:1 macro shot, which comes to a bit more than 1.0 mm long. (See here for how I figured.) The one on the bottom with three "arms" seems to be floating in a puddle of goo. One possibility for ID is Stanford’s Whitefly (Tetraleurodes stanfordi), see p.44 of A Field Guide to Insects and Diseases of California Oaks (PDF), a document worth downloading for California natural history.

Here's a closer photo of (I believe) the tiny scale-like larvae of a Whitefly (Aleyrodidae, Sternorrhyncha, Hemiptera) on the underside of an oak leaf - see this photo from yesterday. They are tiny, less than a millimeter across. One possibility for ID is Stanford’s Whitefly (Tetraleurodes stanfordi), see p.44 of A Field Guide to Insects and Diseases of California Oaks (PDF), a document worth downloading. I believe the actual critters are shiny black disks as in this photo, but they decorate themselves with a waxy white exudate. Each one seems to sit in a little puddle. The oak is interesting too, see my photo from yesterday. (San Marcos Pass, 18 December 2017)
I believe these are tiny scale-like larvae of Whitefly (Aleyrodidae, Sternorrhyncha, Hemiptera) on the underside of a leaf of an interesting oak that I'm still not sure of - maybe Shreve Oak (Quercus parvula var. shrevei) or Quercus wislizeni. (See my [Previous] photo for another photo and some discussion.) One possibility for ID is Stanford’s Whitefly (Tetraleurodes stanfordi), see p.44 of A Field Guide to Insects and Diseases of California Oaks (PDF), a document worth downloading. I usually find these as shiny disk-like pupae that lack the white decorations, see this photo. You can see a couple of them on the very left. The oak is interesting too. Note that it doesn't have the "hairy armpits" of Coast Live Oak, see the leaf in the last link. (San Marcos Pass, 18 December 2017)
