Bactericera salicivora? - Bactericera salicivora

Bactericera salicivora? - Bactericera salicivora
Oso Flaco Lake, San Luis Obispo County, California, USA
December 4, 2016
Size: ~2mm
Found on arroyo willow (Salix lasiolepis); I'm thinking this is another Bactericera salicivora, but the it lacks the long "fuzz" seen on the other nymph and shed

Moved from Psylloidea.

I think so
It's definitely a Bactericera at any rate, and the extent of the marginal setae makes me think it's allied to the other ones you've been finding nearby on that host.

So far all of my Bactericia adults from this site have been Bactericera salicivora. My impression was that this might be an instar ahead of the other one I photographed, but with the teneral Cacopsylla I wanted to run it by you first ;-)

Come to think of it,
Have you photographed any willow Cacopsylla nymphs yet? According to the literature Cacopsylla nymphs feed mainly on the catkins, or on the leaf axils of new growth, without any sort of waxy cover. Most species only move to the leaves right before they're ready to become adults. It looks like there's only one such willow Cacopsylla nymph in the guide so far, but none from the west. I don't know when willows begin to break dormancy in your area but it might be something to be on the lookout for when they do.

No, I haven't photographed any Cacopsylla nymphs on willow. I want to say I've seen non-fuzzy nymphs on willow, but it was before I started making an effort to photograph immature. I'll keep an eye out!

Not on Bugguide...
I do have on flickr that was photographed at this same location on willow, I wasn't really looking for psyllids at that time and didn't figure out what the mite was eating until recently. This was a very small nymph, the mite was ~2mm

Really cool predation shot
I think that one is probably Cacopsylla. Very small indeed!

I should note (for what it's worth), this nymph was on a different tree than the teneral Cacopsylla sp.
