Well, now I at least know what they look like! I can't imagine having trouble getting another dozen.
Are there any species associated with vernal pools? (if you know of any other terrestrial invertebrates that might hang around such habitats, and are endemic to those areas, let me know).
Hmmm, not particularly. Or at least, nothing specific to plants specific to vernal pools. A few species are associated with plants typical of other types of wetlands, such as Livia spp. on Carex and Juncus, Aphalara spp. on Persicaria & Rumex, and Bactericera & Cacopsylla spp. on Salix. But that's about it I'd say.
So no Livia on Eleocharis yet? I can check some of the little Persicaria plants. Are Aphalara on non-native Rumex too (i.e. crispus)?
If there's anything on Eleocharis, nobody knows about it yet :) For our Rumex psyllid, I have records from both native species such as Rumex conglomeratus as well as non-native R. crispus.
As promised here's a list of our native California psyllids, their host plants, and some other data. It's a draft copy, and it's incomplete and not ready for prime time... but all the species and their hosts are there so that's better than nothing. If you go to Data > Filter Views, there are some useful functions for visualizing the data, such as sorting by the host, hiding species not present in certain regions (but note that the data is incomplete for that), or showing only species that have been commonly/rarely collected, etc. Hopefully you may find it useful despite its incompleteness.

Awesome spreadsheets, Chris! Thanks for sharing!
I'm beginning to doubt the existence of psyllids on Artemisia californica! I've looked over and shaken up so many of these from all over Southern CA, including on Santa Cruz, and nada.
Your results mirror mine so far. Checked a bunch of sagebrush in the santa monica mountains yesterday and came up with nothing psyllid-wise.
Perhaps Artemisia tridentata may be more lucrative. At least with that plant, there are confirmed records of nymphs as well as adults, so the host confirmation is definite.
