A polyphagous spider mite found in Asia, the Americas and Oceania causing feeding damage which results in defoliation and reduced yields. To date impacts reported on crops of relevance to the UK have been limited to grapevines, but there is the potential it could represent a threat to other hosts if it were to establish.
