2017 target species Part 1: Psyllids
I don't think it's too crazy to aim to photograph at least 100 new-to-me Hemipterans in the coming year... it wouldn't be too unreasonable for 30 of those to be psyllids, right?

Good luck with these! I'm hoping to try and find a few of my own. Lots of mistletoe fell recently because of the winds, sadly no sign of psyllids on those yet.
What's the plant being referred to as "hackberry?"
Thanks! Good luck to you too. The mistletoe psyllids, especially Freysuila phorodendri, are definitely at the top of my list. I've seen records of it from Los Angeles, San Bernardino, Riverside, and Kern counties, from Phoradendron villosum, P. tomentosum, P. leucarpum, & "Phoradendron on Sycamore". Most of those records seem to be from May. I don't know anything about the life history, unfortunately. It's possible that they overwinter as adults.
For Hackberry, genus Celtis (C. occidentalis, C. reticulata, C. tenuifolia, & C. laevigata). A couple species have been introduced into CA, but they mostly occur in the eastern US.
The sycamore species is Phoradendron macrophyllum (AKA P. leucarpum ssp. macrophyllum, or P. serotinum, depending on who you ask). The one I also would love to find is that awesome Calystegia Bactericera. I find it a novelty that something specializes on the often diminutive foliage of that vine.
That's another really cool one that probably should have made my list. I know Cedric found one last year pretty locally and there are actually quite a lot of unpublished records of it throughout the state. Definitely one to look for.
Do you think they might also try Convolvulus arvensis? Guess there is only one way to find out.
Read up on Pachypsylla cohabitans and wasn't disappointed. Wonder if you can tell they are there without opening the gall first?
I have records of it from Convolvulus arvensis, Convolvulus occidentalis, and “Convolvulus ludiolus” (I don't know what plant that record refers to, exactly) so they seem to have a broad appetite for Convolvulaceae.
On P. cohabitans, I seem to recall reading that affected galls may appear somewhat 'lumpy' due to having multiple cells per gall, as opposed to smoothly rounded monothalamous galls. Yang, Mitter, & Miller's publication describing the species and detailing their experiments is a really interesting read:

It's definitely a fascinating species. Very under-represented though! I left a comment on bugguide the other day regarding what appears to be one of just two images I've seen definitively depicting the species:

Hopefully when I'm on the east coast later this year I can collect some galls and get some photos of it. Also hope to rear some hackberry star galls, as there are no images of the adults of that species either.
In that area there is Convolvulus arvensis (introduced) as well as several Calystegia (most prominently purpurata and subacaulis). I'm not familiar with that name, although there is an old-world taxon called lucanus, which is a hybrid of Calystegia sylvatica and sepium.
What does Cacopsylla notapennis look like? Does it look nothing like a Cacopsylla? Because I might have found it.
