Not sure where to go with this one. I can't remember where I found it (I really need to get these photos processed faster or take some notes at the time at least).

Moved from Aphalaridae.

Possibly Craspedolepta nebulosa kincaidi
C. nebulosa has a holarctic distribution, the nominate subspecies widely recorded throughout Europe. Ashmead's Aphalara kincaidi, recorded from Canada and Alaska, was synonymized with C. nebulosa in 1914 by Crawford.

While the nearctic kincaidi is poorly represented online, the european C. nebulosa has a large web presence and many images are available for comparison (for example, here, here, here, here, here). Other than structural differences in the genitalia not visible here, Crawford notes that the American subspecies has wings more lightly-maculated than the European subspecies, a fact reiterated by Patch's illustration (which I've uploaded here - compare against Hodkinson & White's illustration of the nominate subspecies here (fig 54)). Indeed, your species has wing maculation very much like the nominate subspecies though lighter and less pronounced, as would be expected from kincaidi. In terms of coloration, your psyllid matches perfectly Ashmead's original description.

The Alaskan Psylloidea were covered most recently and fairly thoroughly by Hodkinson (1978), though Hodkinson's key relies primarily on genitalia characters not visible here. The most similar species known from the region are C. alaskensis, a darker more heavily-maculated species, and C. schwarzii, a species dismissed by both Hodkinson and Crawford as probably synonymous with C. alaskensis. Your psyllid does not seem to agree with Ashmead and Crawford's descriptions of those species.

All things considered, I expect this is probably Craspedolepta nebulosa kincaidi, but the ID is tentative primarily because I have not been able to obtain Journet & Vickery's 1979 review of the genus, in which they describe many new species; although none of those species are described from Alaska, I can't be certain at this time if any of those may be a better match.

Very cool!
It's a psyllid, I suspect genus Craspedolepta (of which there are at least 4 spp. in alaska). But don't take my word for it... hopefully somebody more knowledgeable with psyllids will be to look at this and be able to verify.
