Piesma
ash-grey leaf bugs
Piesma is a genus of small ash-grey leaf bugs in the family Piesmatidae, serving as the type genus of the family. Members are less than 4 mm in length and occur across North America, Europe, Africa, and Asia. The genus is distinguished from the similar genus Parapiesma by a notch in the side margins of the pronotum. Species in this genus are primarily phytophagous and include economically significant pests such as Piesma quadratum, which transmits viral and rickettsia-like pathogens to sugar beet and related crops.
