possibly a worn Adela flammeusella? But it didn't fold its wings as photos seem to show, but perhaps that was because it was breezy on this hilltop and it was stabilizing itself?
White Delphinium species about 5 foot high? Difficult to key this out, given that I've lost any photos that might have shown other characters. Also the precise location is lost, but I know it was close to the middle of the Sierras on the High Sierra Trail, probably in the Kern River canyon.
Tentative ID. A sweet little cricket with a big sound. I have a recording but will have to upload later.
Revealed yellow where rubbed, then dark brown and insides.
Nearest tree is a Eucalyptus.
An old photo from a colony containing both C.pulchellus and C.umbellatus . This is the rare hybrid of the two.
An observation from May 2017, before I joined INaturalist. A mating pair. Found them on Buffalo gourd. ID'ed by Bugguide. https://bugguide.net/node/view/1371945
This is “take two” after my first Pixie Cup Lichen obs two days before, https://www.inaturalist.org/observations/36422663. I went back to the area for a closer look and hopefully better pictures. Back at home, I searched through all iNat Pixie Cup Lichen observations in California and tried to find a species that matches what I saw in the field.
It could be Rosette (C. pocillum) because of the mat-forming Thallus. (https://lichenportal.org/cnalh/taxa/index.php?taxon=53451&clid=1162, http://www.lichensmaritimes.org/index.php?task=fiche&lichen=304&lang=en).
I can’t rule out Mealy (C. chlorophaea). (https://lichenportal.org/cnalh/taxa/index.php?taxon=53388&clid=1212)
@j-dar had considered C. pulvinella (https://lichenportal.org/cnalh/taxa/index.php?taxon=53458&clid=1130).
It’s not Pebbled (C. pyxidata) because there are no distinct pebbles inside the cups. (https://ohiomosslichen.org/lichen-cladonia-pyxidata/)
It’s not Firm Cup (C. firma), because per lichenportal, C. firma’s podetia are rare and rarely proliferating from center. Plus j-dar had ruled it out too. (https://lichenportal.org/cnalh/taxa/index.php?taxon=Cladonia%20firma)
It’s not Western (C. asahinae) because the podetia are not flaring abruptly (https://lichenportal.org/cnalh/taxa/index.php?taxon=53371).
It’s not Trumpet (C. fimbriata), because of the shape and number of podetia. (https://lichenportal.org/cnalh/taxa/index.php?taxon=53409&clid=1102)
Over to the specialists, like @mossgeek, @j-dar, @catchang and @metsa. Thank you for your input!!
On madrone.
