Eotetranychus lewisi (McGregor, 1943) - (Lewis spider mite)
This polyphagous spider mite is native to the Americas and has been originally described from citrus trees in California, U.S. It is invasive and has been reported from various other regions on a variety of host plants. In Europe, it is a quarantine pest and is regarded as established only in parts of Madeira, Portugal (EPPO 2020). However, there have been reports from greenhouses of other European countries like Switzerland and the Netherlands (EPPO 2021).
Common host plants of E. lewisi are fruit trees, strawberries and poinsettias (Euphorbia pulcherrima). Colonies are formed on the underside of the leaves together with some webbing. The adult mites are less than 0.5 mm long, slight smaller than the two-spotted spider mite, and with 4 or more spots on the body.
