Bactericera sp. - Bactericera salicivora - Female
Oso Flaco Lake, San Luis Obispo County, California, USA

Found on arroyo willow (Salix lasiolepis) bordering dune lake; I only found this teneral adult and a nymph

Bactericera sp. - Bactericera salicivora - female Bactericera sp. - Bactericera salicivora - female

Moved from Bactericera.

Moved from Psylloidea.

Found on the same leaf as , there was also a fuzzy empty exuvia that this adult may have emerged from on the leaf

I just realized that in , the fuzzy mass is the nymph excuvia; likely the same as whatever these are

Looking through my photos, all my male Bactericera from this site are B. salicivora:

while all the females are unidentified

Could these all be the same thing? The females seem like they would fit colorwise within the variation described for B. salicivora. The nymph would be the sticking point. describes the nymph as glabrous and I think the repeated associations (teneral adults next to exuvia) with these fuzzy nymphs points to these being the immatures. Maybe the literature has the wrong nymph? Or, these are all something else? I'm just finding the sex break down suspicious...

I think you're absolutely right
After reexamining this series, I do believe they all must be salicivora. About the nymphs: they are definitely Triozid and therefore are highly probably associated with these adults. I consulted the literature and it looks like the glabrous nymph description originates from a european author, F. Loew, in 1884. The problem? In that time, B. salicivora used to be considered to be a holarctic species going by the name of B. maura. American authors, believing that the American species was the same as the European one, borrowed descriptions of the European species in certain instances where it was convenient, including the nymph description. Therefore, the published descriptions of B. salicivora nymphs all describe a different species and are not useful.

So what does a B. salicivora nymph look like? I don't have any current literature that describes it, but it probably looks just like yours. The other common American species, B minuta, is one that I've found quite often and is quite different, mostly glabrous with only the smallest fringe of marginal setae. The other four Salix-feeding Triozids don't quite match up to the adults, so B. salicivora seems most likely.
