More work, both collecting and taxonomic is required for this family (257
NA spp). Roughly 12 species have been collected, but more certainly are
present.
Aphalara
(2 spp) are taken in small numbers in old field sweeps. Host unknown, but
one appears associated with Canary Grass (Phalaris arundinaceum).
Other field species are Livia
(2 spp). Members of the genera
Pachypsylla
(1 sp), Psylla (4+
spp), and Trioza (4+spp) are associated with woody plants
in woodlands. Trioza tripunctatacan
be common on Rubus. Some undetermined
nymphs are also imaged.
