Have you seen this bug? Scientists call on Britain’s gardeners to track elusive aphid

The elusive giant willow aphid goes into hiding in spring. Now the Royal Horticultural Society wants volunteers to help find out why

Gardeners have been urged by scientists to help find a mysterious bug which disappears in spring and reappears at the end of summer.

The Royal Horticultural Society (RHS) is asking people to send in sightings of the giant willow aphid (Tuberolachnus salignus) so that they can find out where it goes and how it interacts with garden plants.
