Guides
Bactericera lobata
Bactericera lobata is a psyllid species (family Triozidae) first described by Crawford in 1914. As a member of the genus Bactericera, it belongs to a diverse group of phloem-feeding insects commonly known as jumping plant lice. The species is recorded from the southwestern United States and northern Mexico. Like other psyllids, it likely feeds on plant phloem sap, though specific host associations remain poorly documented. The genus includes economically significant species such as the potato psyllid (B. cockerelli), but B. lobata itself has received limited research attention.
Euglyptoneura robusta
Euglyptoneura robusta is a species of jumping plant louse in the family Psyllidae, order Hemiptera. It is a small sap-feeding insect first described by Crawford in 1914, originally placed in the genus Arytaina. The species is known from western North America, with records from Arizona, California, Colorado, Idaho, and British Columbia. Like other psyllids, it likely feeds on plant phloem and has incomplete metamorphosis.
Isodelphax nigridorsum
A small delphacid planthopper species described by Crawford in 1914. Known from limited records across northeastern and north-central North America. The species epithet "nigridorsum" refers to a dark or black dorsal surface. Like other delphacids, it possesses a distinctive movable spur on the hind tibia, a diagnostic feature of the family.
Livia caricis
sedge psyllid
Livia caricis is a psyllid species in the family Liviidae, first described by Crawford in 1914. It belongs to the genus Livia, which comprises psyllids associated with sedges (Carex spp.). The species is found in western North America, with distribution records from British Columbia, California, Colorado, and Idaho. Like other psyllids, it is a small sap-feeding insect with host-specific relationships to its plant hosts.
Megamelus flavus
Megamelus flavus is a species of delphacid planthopper in the family Delphacidae, described by Crawford in 1914. It belongs to the genus Megamelus, a group of planthoppers associated with aquatic and semi-aquatic habitats. Distribution records indicate presence in northern North America and parts of Asia.
Neophyllura arbuticola
Arizona Madrone Psyllid
Neophyllura arbuticola is a psyllid species in the family Liviidae, first described by Crawford in 1914. The species is associated with madrone (Arbutus) host plants, as indicated by its specific epithet. It is known from limited observations in Arizona. The genus Neophyllura comprises psyllids that feed on various host plants, though species-level biological details remain poorly documented for many members.
Stenocranus similis
Stenocranus similis is a species of delphacid planthopper in the family Delphacidae. It was described by Crawford in 1914 and is found in North America, with records from Alabama, Illinois, Kansas, Kentucky, and Mississippi. As a member of the subfamily Stenocraninae, it belongs to a group of planthoppers characterized by particular morphological traits and ecological associations with grasses and sedges.
