The heaviest population densities are in June and July in the northern hemisphere, just when the bushes are flowering, and thereafter the populations decline. This is because at this time of year, some winged females develop, which migrate to other rose bushes or to certain secondary hosts such as
235:. They have a world-wide distribution and infest rosebushes as the main host in spring and early summer, congregating on the tips of shoots and around new buds. Later in the summer, winged forms move to other rose bushes, or to a limited number of secondary hosts, before returning to rosebushes to lay eggs in the autumn.

Wingless adults have a spindle-shaped body and are between 1.7 and 3.6 mm (0.07 and 0.14 in) long, slender, varying in colour from green to pink and reddish-brown. The antennae and legs are relatively long, and the cauda (tail-like protrusion) is pale. The
