Hosts

Approximately 20 recorded species of host plant, including mainly Poaceae: Bambusa sp. (Poaceae), Ficus stipulata (Moraceae), Oryza sativa, Phyllostachus makinoi, P. nigra, P. reticulata, Pleioblastus shibuyanus, *Pseudosasa japonica, Saccharum officinarum, S. spontaneum, Sasa kurilensis, Sas. nipponica, Sas. senanensis (Poaceae)

Biology

This species is a common pest of bamboo in Japan and an occasional pest of rice and sugarcane.  Like its relatives in Schizotetranychus, these mites live in discrete colonies under dense webbing, located on the underside of leaves.  Their feeding causes chlorotic spots that can be seen on the upper surface of the leaves as white spots.
