Guides
Calophya oweni
A small psyllid in the family Calophyidae, described by Tuthill in 1939. Very little published information exists on this species. The few available records suggest it occurs in western North America. As with other Calophya species, it likely develops on specific host plants, though these remain undocumented for this particular species.
Neotriozella hirsuta
Neotriozella hirsuta is a psyllid species in the family Triozidae, described by Tuthill in 1939. It belongs to a genus of jumping plant-lice that feed on vascular plants. The species epithet 'hirsuta' refers to hairy characteristics, though specific morphological details remain poorly documented in accessible literature. Like other Triozidae, it likely has a complex life cycle involving multiple nymphal stages and host plant specificity.
