This species is a vector of green petal virus of strawberry in England, which is the same virus causing clover phyllody (Chiykowski 1962 [136]). It was first reported as a vector of this virus in the East Malling Research Station Annual Report of 1961 (223). In 1963, Posnette and Ellenberger (623) reported it as a vector of green petal virus of strawberry, but did not present details of the transmission experiments.
(Nielson 1968)

The importance of this species in the natural spread of this virus is pending further investigations.
