Psyllid species on BugGuide but not yet on iNat

BugGuide has long reigned supreme in terms of nearctic psyllid representation but iNat has closed the gap recently. This list details a few species that iNat observers have yet to document.

APHALARIDAE (26/29 bugguide species)

  1. Aphalara monticola
  2. Aphalara persicaria
    Notes: Aphalara spp. are difficult to ID from photos. I can't confirm the ID of the A. monticola specimen on Bugguide, and it is unlikely that Aphalara species on iNat may be identified without a good shot of the genitalia. iNat should aim for more Aphalara observations (we only have 16) but species ID shouldn't be expected.

  3. Pachypsylla cohabitans - Inquiline Hackberry Leaf Gall Psyllid
    Notes: Similar to other leaf-galling Pachypsylla, but supposedly distinguishable by the green abdomen (as opposed to brown), which may be difficult to see in photos. Additionally, this species does not create galls of its own but instead inhabits galls of other Pachypsylla species. Particularly lumpy celtidismamma galls may house multiple cells in which the inquiline species may inhabit.

HOMOTOMIDAE (2/2 bugguide species - great!)

CALOPHYIDAE (7/7 bugguide species - great!)

LIVIIDAE (11/13 bugguide species)

  1. Livia bifasciata
    Notes: Look for galls on Juncus canadensis in the northeastern US and Canada

  2. Livia saltatrix
    Notes: On sedges in northeastern US and Canada

PSYLLIDAE (60/64 bugguide species)

  1. Heteropsylla huasachae
    Notes: Probably already on iNat. Difficult to ID from photos.

  2. Amorphicola pallida
    Notes: Look for these on Amorpha canescens in the midwest.

  3. Cacopsylla sinuata
    Notes: A willow psyllid from northern US and Canada. The willow-feeding Cacopsylla are very difficult and often impossible to identify without examination of the genitalia; iNat has many observations of willow-feeding Cacopsylla but further ID is unlikely. Of the 24 species of Cacopsylla identified on bugguide, this is the only one absent on iNat, which is pretty impressive (and actually, iNat has two additional Cacopsylla spp. that bugguide does not).

  4. Psylla betulaenanae
    Notes: A circumpolar species found on dwarf birch, Betula nana. The nymphs are similar to other Psylla spp and are often accompanied by white fluff, which is often the most conspicuous way to find them. There is one observation on iNat which I suspect to be this species.

TRIOZIDAE (27/34 bugguide species)

  1. Bactericera athenae
    Notes: A little-known species similar to B. antennata. The hostplant and full range of the species is unknown.

  2. Calinda longicaudata
    An easily recognizable southwestern psyllid on Baccharis pteronioides

  3. Ceropsylla sideroxyli
    A southern Florida specie. The white waxy shelters that the nymphs build on Sideroxylon leaves are very conspicuous, and I would not be surprised if these have been inadvertently photographed and filed somewhere on iNat already.

  4. Hemitrioza sonchi
    A fascinating species unlike any other in the nearctic fauna. Found in the eastern US on Sonchus, apparently

  5. Neotriozella pyrifola
    An eastern US species in a genus most easily recognized by form of the genal cones. No host plant has ever been formally recorded, but the bugguide collection was taken from Styrax, and that host should probably be investigated further.

  6. Trioza aylmeriae
    An amelanchier-feeding psyllid in the northern US and Canada

  7. Trioza quadripunctata
    A very well-marked nettle-feeding psyllid. While the other north american nettle feeding species Trioza albifrons is well-represented on iNat, this one has yet to be recorded.

Of the 149 psyllid species represented on bugguide, iNat has all but sixteen. iNat similarly has 11 nearctic species that are unrepresented on bugguide. In total about 160 species are represented across both platforms, which accounts for roughly half of the nearctic fauna.
