Spanioneura
Spanioneura is a genus of psyllids (jumping plant-lice) established by Arnold Förster in 1848. Species are primarily European in distribution, though the type species S. fonscolombii has been accidentally introduced to the United States. The genus comprises at least five described species, with S. fonscolombii being the most widely studied due to its economic significance as a pest of boxwood (Buxus species).
Spanioneura buxi
boxwood psyllid
Spanioneura buxi, commonly known as the boxwood psyllid, is a sap-feeding insect in the family Psyllidae that infests boxwood (Buxus species). The species produces distinctive cupped or curled terminal leaves on host plants, caused by nymphal feeding and wax secretion. It has a single generation per year in temperate regions. The insect is considered a minor pest that causes primarily cosmetic damage, with most boxwood plants recovering without permanent injury.
Spanioneura fonscolombii
Spanioneura fonscolombii is a plant-parasitic psyllid specialized on box (Buxus) species. First described from Europe in 1848, it has been accidentally introduced to the United States and represents a pest of ornamental and native boxwoods. The species shows distinctive green coloration with patterned wings and has been documented causing damage to host plants, with some dispute regarding gall formation.
