Petrobia Hemerocallis
''Petrobia'' is a genus in Tetranychidae (spider mites), containing 34 described species. It includes some pest species. Description ''Petrobia'' mites can be recognised by their reddish-brown cuticle, dark body contents and the first leg pair being very long. Each leg ends in pad-like claws and a hooked (uncinate) empodium with more than 1 pair of tenent hairs. The prodorsum of the body has three pairs of setae (''ve'', ''sci'', ''sce'') and there are no prominent lobes over the gnathosoma. The paranal setae (''h2-3'') are in a ventral position. The genus is usually divided into three subgenera: ''Mesotetranychus'', ''Petrobia'' and ''Tetranychina'' (sometimes one or more of these are considered separate genera). ''Mesotetranychus'' has simple peritremes whereas ''Petrobia'' has anastomosing peritremes. ''Tetranychina'' usually has long dorsal setae on small tubercles (other subgenera sometimes have tubercles as well, but their dorsal setae are short). Reproduction Species ...

Tetranychidae
Spider mites are members of the Tetranychidae family, which includes about 1,200 species. They are part of the subclass Mite, Acari (mites). Spider mites generally live on the undersides of leaf, leaves of plants, where they may spin protective silk Spider web, webs, and they can cause damage by puncturing the plant Cell (biology), cells to feed. Spider mites are known to feed on several hundred species of plants. Description Spider mites are less than in size and vary in color. They lay small, spherical, initially transparent egg (biology), eggs and many species spin silk webbing to help protect the Colony (biology), colony from Predation, predators; they get the "spider" part of their common name from this webbing. Life cycle Hot, dry conditions are often associated with population build-up of spider mites. Under optimal conditions (approximately 27 °C), the two-spotted spider mite can hatch in as little as 3 days, and become sexually mature in as little as 5 days. One ...
