Cuckoo spit

Time to act:

Jun, Jul, Aug, Mar, Apr, May, Sep, Oct, Nov

Protected from predators and the risk of dehydration inside its moist ball of bubbles, the juvenile yellow-green froghopper (or spittle bug) is busy sucking plant sap. It's quite harmless unless it's attacking the shoot tips, which can result in distorted growth. The adult froghoppers (which don't produce any spit) are 6mm long and bright green, with large eyes and a blunt-shaped head, but they're rarely seen because they hop away on their strong back legs at the first sign of danger.

Symptoms

Blobs of white froth on the stems, leaves and flower buds of plants.

Find it on

roses, dahlias, fuchsias, lavender, rosemary and many garden plants

Cuckoo spit is a temporary inconvenience. Once autumn arrives froghoppers die off, having laid the next generation of eggs. You can either brush the spit off with your hand, or you can wash it off with the hose.
