Psyllids
Guides
Amorphicola
Amorphicola is a genus of jumping plant lice (psyllids) in the family Psyllidae, established by Heslop-Harrison in 1961. As psyllids, members of this genus are small, sap-feeding insects with characteristic jumping ability enabled by their enlarged hind femora. The genus belongs to the diverse psyllid radiation within the suborder Sternorrhyncha.
Aphalaridae
jumping plant lice, psyllids, lerp insects
Aphalaridae is a family of sap-sucking insects in the superfamily Psylloidea, commonly known as jumping plant lice or psyllids. The family contains approximately 749 species with worldwide distribution except Antarctica. Members are small, phloem-feeding insects, often highly host-specific. The family was revised in 2012 and 2021 to include seven subfamilies based on molecular and morphological data. Several species are significant agricultural and forestry pests, including the red gum lerp psyllid (Glycaspis brimblecombei) and the common pistachio psyllid (Agonoscena pistaciae).
Aphalarinae
Aphalarinae is a subfamily of true bugs in the family Aphalaridae, order Hemiptera. It comprises multiple tribes including Aphalarini, Caillardiini, Colposceniini, Gyropsyllini, and Xenaphalarini, with both extant and extinct genera. The subfamily contains at least 15 extant genera and several fossil taxa. Members are psyllids, a group of sap-feeding insects commonly known as jumping plant lice.
Calinda
Calinda is a genus of psyllids (family Triozidae) in the order Hemiptera, first described by Blanchard in 1852. Psyllids are small plant-feeding insects commonly known as jumping plant lice. The genus belongs to the suborder Sternorrhyncha, a group characterized by piercing-sucking mouthparts and often complex host plant relationships. As of current records, the genus contains multiple species, though specific taxonomic boundaries and species counts require further verification.
Ciriacreminae
Ciriacreminae is a subfamily of psyllids within the family Psyllidae, comprising small plant-feeding true bugs in the order Hemiptera. Members of this subfamily share the general characteristics of Psyllidae, including jumping ability and typically host-specific feeding relationships with plants. The subfamily is part of the Sternorrhyncha, a group considered basal within Hemiptera that includes aphids, scale insects, and whiteflies. Specific diagnostic features distinguishing Ciriacreminae from other psyllid subfamilies are not well documented in widely available literature.
Euphalerus
Euphalerus is a genus of jumping plant lice (psyllids) in the family Psyllidae, first described by Schwarz in 1904. Members of this genus are small sap-feeding insects that inhabit the New World tropics and subtropics. The genus is distinguished by specific wing venation patterns and genitalic structures characteristic of the Psyllidae family. Euphalerus species are associated with various host plants, though specific associations remain incompletely documented.
Freysuila
Freysuila is a genus of jumping plant lice (psyllids) in the family Psyllidae, established by Aleman in 1887. As members of the superfamily Psylloidea, these insects are small, plant-feeding hemipterans with characteristic jumping hind legs. The genus is poorly documented in scientific literature, with limited species-level information available. It belongs to a diverse group of phytophagous insects that specialize on vascular plants.
Liviidae
plant lice, psyllids, jumping plant-lice
Liviidae is a family of plant-parasitic hemipterans commonly known as plant lice or jumping plant-lice. The family comprises more than 20 genera and approximately 370 described species worldwide. Members are characterized by their ability to jump and their association with vascular plants as phloem-feeders. The family includes significant agricultural pests, most notably Diaphorina citri (Asian citrus psyllid), the primary vector of citrus greening disease (Huanglongbing). Liviidae was formerly treated as Triozidae, and recent taxonomic revisions recognize three monophyletic subfamilies: Euphyllurinae, Liviinae, and the monotypic Neophyllurinae.
Neotriozella
Neotriozella is a genus of psyllids (family Triozidae) established by Crawford in 1911. These small sap-feeding insects belong to the hemipteran superfamily Psylloidea, commonly known as jumping plant lice. Members of this genus are poorly documented in contemporary literature, with limited species-level information available. The genus is distinguished from related triozid genera primarily by genitalic and wing venation characters used in psyllid taxonomy.
Psylla
jumping plant lice, psyllids
Psylla is the type genus of the family Psyllidae, comprising small sap-sucking insects commonly known as jumping plant lice or psyllids. The genus contains at least 110 described species, each typically associated with specific host plants. Psylla species are phloem-feeders that use piercing-sucking mouthparts to extract plant sap. While some species in related genera such as Cacopsylla are significant agricultural pests, Psylla itself includes species with more restricted host ranges, including Psylla alni on alders, Psylla betulae on birches, and Psylla buxi on boxwood. The genus is distinguished from similar taxa by morphological features and host associations.
Psyllinae
Psyllinae is a subfamily of plant-parasitic hemipterans within the family Psyllidae, comprising approximately 12 genera and at least 40 described species. Members are commonly known as psyllids or jumping plant lice. The subfamily includes economically significant pest species such as the apple psylla (Cacopsylla mali) and pear psylla (Cacopsylla pyri). Species exhibit biogeographic patterns correlating with altitude and regional flora, with Oriental elements dominating at lower elevations and Himalayan and Australian elements prevalent above 2500 m in montane systems.
Rhinocolinae
Rhinocolinae is a subfamily of jumping plant lice (psyllids) within the family Aphalaridae. The subfamily comprises approximately 15 genera, including both extant and one extinct genus (†Protoscena). These insects are small, phloem-feeding Hemiptera associated with host plants, though specific biological details for the subfamily as a whole remain poorly documented in available literature.
