Bactericera arbolensis
Bactericera arbolensis is a small psyllid species first described from Arboles, Colorado in 1910. It is associated with Shepherdia species (buffaloberry), particularly Silver Buffaloberry (Shepherdia argentea) and Canadian Buffaloberry (Shepherdia canadensis). The species is poorly known, with few literature records from Montana, Wyoming, and Colorado. A 2014 observation from Cheyenne Mountain Zoo in Colorado suggested potential wing morphology variation or possible undescribed related species, highlighting the need for further study.
Bactericera shepherdiae
Bactericera shepherdiae is a small psyllid species in the family Triozidae, described by Tuthill in 1938. It is associated with buffaloberry plants (Shepherdia spp.), specifically Silver Buffaloberry (Shepherdia argentea) and Canadian Buffaloberry (Shepherdia canadensis). The species is poorly documented and appears to be uncommon, with limited records from western North America. It is one of approximately 24 Bactericera species known from North America north of Mexico.
Capitophorus shepherdiae
Buffaloberry Oleaster Aphid
