distribution and habitat

The two- spotted whitefly is widespread from all of Europe eastwards through Russia (there in the ssp. Subnotata ) to East Asia ( Japan and Korea ). The species occurs in the southern Alps only in lower elevations. It prefers to live on bushy deciduous forest edges, in forest clearings, on river banks as well as in gardens and parks.

Way of life
