Psyllid species on BugGuide but not yet on iNat
iNat's representation of psyllid diversity continues to grow, currently represented by 211 species globally and 118 species in North America (about a third of the US fauna). But there are still holes, especially in central/eastern USA as well as Alaska, and 31 nearctic species are still absent on iNat despite being present on BugGuide. Let's fill the gaps!
