Plant: Cane Cholla (Cylindropuntia bernardina)
@nancyasquith @susanmf @cwbarrows Have you seen this too? It appears similar to the pic on Gallformers of an unknown fruit gall on Tree Cholla (Cylindropuntia imbricata). Your feedback, please. Thank you.
Plant: San Jacinto Beardtongue (Penstemon clevelandii connatus). @tchester @nancyasquith @cwbarrows @susanmf This is the first time I’ve ever seen this. It reminds me of Contarinia on Epilobium. Your thoughts, please!
A baby with cotyledons!
(UR). Host plant: Acton Brittlebush (Encelia actoni)

The moth was so well camouflaged. I only saw it because I was taking a photo a few inches away. It appears to have a gold "metallic" or shiny fringe at wing margins and was about 1 inch long.

Coachella Valley Preserve: For thousands of years, particles of sand from the San Bernardino Mountains and Indio Hills washed into the Coachella Valley forming a system of sand dunes. Today, these dunes are part of the Coachella Valley Preserve System, a 20,000-acre sanctuary.
The Coachella Valley Preserve also contains several palm oases that sit on top of San Andreas Fault lines. Underground water rises to the surface through these cracks. California Fan Palms (Washingtonia filifera) grow along the cracks where the water seeps up creating a desert oases. Many plant species thrive in the alkaline soil.
Coachella Valley sits at the convergence of four vast ecological systems - the Colorado (or Sonoran) Desert, the Mojave Desert, and the coastal and peninsular mountain ranges.

California Fan Palm (Washingtonia filifera) A.k.a. Desert Palm. It is California’s only native palm tree. These palms often grow over seeps, springs, rivlets—wherever there is a regular source of water. They can be seen along (earthquake) fault lines on east side of the Coachella Valley. The cross-section of the trunk looks like vertical packed-together straws. Peak bloom time: February-June. Hard, pea-sized fruits are sweet and datelike in flavor. The fruits are an important food source for coyotes and many species of birds. Native people ate the berries, both fresh and dry, and ground the seeds into meal. The fallen fronds and still-hanging "skirts" provide excellent shelter and habitat for many species of birds, bats, owls, rodents, reptiles, insects and other animals.
The California Fan Palm was a very important plant with many uses for the local desert Cahuilla people. They added the small, sweet fruits fresh or dried to flavor foods. The most common use of the long fronds was in house construction to make the homes both waterproof and windproof. Palm frond stems were used to make cooking utensils, particularly spoons and stirring implements. Palm leaves were used to make sandals or foot pads. 17 traditional uses described here:

Two trees had grown together- one had died and the other still lives
I came across a couple of California Croton plants that were hosting many galls.
I searched @nancyasquith's collection and lists, https://www.inaturalist.org/projects/california-plants-with-mystery-galls, as well as the Russo guide, but couldn't find anything.
I'm posting this observation for the host plant, hoping we can find the gall inducing insect...
On California Croton, Croton californicus
I am only guessing!!
Host = Encelia farinosa
Host = Arctostaphylos
Gall on Encelia californica.
This trunk was washed down in a flash flood on 10 September 2004, over 18 years ago, and it is just starting to decay at the end next to the trail. See:

Thanks to Mark Fisher at the Philip L. Boyd Deep Canyon Research Center for finding and sharing this population in bloom this year! This species was last recorded in Deep Canyon in 1978: https://www.cch2.org/portal/collections/individual/index.php?occid=1490992
Plant: Creosote Bush (Larrea tridentata). @nancyasquith @cwbarrows @susanmf Please identify! The first time I’ve seen this, and I’m puzzled. I looked at every stem gall in Russo’s Plant Galls of … and Gallformers, without any match.
With a Pathogen?
Odd growth on brittlebush
Plant: Brittlebush (Encelia farinosa). @nancyasquith, @cwbarrows, @susanmf I know this gall is typically found on Saltbush (Atriplex). Have you seen A. floccosa on Encelia farinosa, or is this a different species?
Best guess on ID
Host = Sphaeralcea ambigua
www.gallformers.org Unknown s-ambigua-abrupt-stem-swelling
Host = Bahiopsis parishii
There was no larvae in the gall
Never seen this before on B.parishii - maybe a mite
A. resinosa or maybe l-tridentata-fringed-cup-galls - found on the same plant as others of the latter.
Collected gall from Ceanothus verrucosus on 4/11/21.
https://www.inaturalist.org/observations/73583630
Gall cut open to find larvae inside on 4/21/21 and placed in container with a cup of soil.
https://www.inaturalist.org/observations/74768171
7 midges emerged today.
Last photo is to document the host plant. 4th photo is a cropped version of the last photo which has the insect gall in question in the lower left while A. trixa is found in the top half of the photo.
Host = Canyon Live Oak
Host = Ericameria
