Stigmaeidae
Guides
Eustigmaeus
Eustigmaeus is a diverse genus of mites in the family Stigmaeidae containing more than 130 species with worldwide distribution across all zoogeographic regions except Antarctica. Species within this genus exhibit complex life cycles that may include an unusual tritonymphal stage, a trait documented in only two species within the family. Some species are associated with moss as a food source, while at least one species, E. johnstoni, has been recorded as an ectoparasite of sand flies. The genus is characterized by distinctive morphological features including specific arrangements of dorsal setae and shield structures.
Zetzellia mali
apple mite, Zetzellia mite
Zetzellia mali is a predatory mite in the family Stigmaeidae, widely distributed across apple-growing regions of the world. This small arachnid serves as an important natural enemy of phytophagous mites in orchards, particularly targeting spider mites (Tetranychidae) and eriophyid mites. The species exhibits a three-generation annual life cycle in temperate climates, with adult females overwintering in protected locations on host trees. While less efficient at population regulation than some competing predatory mites such as phytoseiids, Z. mali contributes significantly to biological control in integrated pest management programs.
