Bryobia
clover mites
Bryobia is a genus of spider mites in the family Tetranychidae, comprising over 130 described species with difficult taxonomy and many likely synonyms. These mites are among the largest spider mites, visible to the naked eye, and are distinguished by the arrangement of setae on their bodies. Most species reproduce asexually through thelytokous parthenogenesis, producing all-female populations. Several species are economically significant agricultural pests, including B. praetiosa (clover mite), B. rubrioculus (brown mite), and B. kissophila (ivy mite).
Coccidae
soft scales, wax scales, tortoise scales
Coccidae is a family of scale insects in the superfamily Coccoidea, commonly known as soft scales, wax scales, or tortoise scales. The family contains over 1,100 species in 171 genera worldwide. Females are typically flat with elongated oval bodies and smooth integument often covered with wax; they may possess legs in some genera but not in others. Males may be winged or wingless. Coccidae are distinguished from armored scales (Diaspididae) by their soft, waxy covering rather than a hard, separable scale. Many species are economically important agricultural and horticultural pests.
Pulvinaria
cottony cushion scales, soft scales
Pulvinaria is a genus of soft scale insects (family Coccidae) characterized by females that produce conspicuous cottony or flocculent wax ovisacs to protect their eggs. The genus includes economically significant agricultural and ornamental pests with broad host ranges spanning numerous woody plant families. Several species have invasive potential and have established beyond their native ranges, including P. aurantii, P. psidii, and P. urbicola. The genus exhibits considerable morphological variability, complicating species identification.
Zeuzera
Leopard moths, Wood-boring moths
Zeuzera is an Old World genus of carpenter moths (family Cossidae) comprising approximately eight currently recognized species. The genus includes significant agricultural pests, notably Zeuzera pyrina (leopard moth), whose larvae bore into the wood of fruit and ornamental trees causing substantial economic damage. Members of this genus are characterized by their wood-boring larval habit and broad distribution across Europe, Asia, and Africa. Several former species have been reclassified to other genera, including Zeuzera boisduvalii which was moved to the new genus Davidlivingstonia in 2020.
