Cuckoo spit

Cuckoo spit

Question ...

Several of my plants in the garden look as if someone has spat on them (which no one has). What is this, and is it a pest, if so, what can be done?

Answer ...

The spit that you have noticed on your plants is often called, 'cuckoo spit'. It is caused by the larvae of an insect called a froghopper. The insect sucks sap from the plant but generally does little harm. Spray the plants with a jet of water to wash off the insects and the 'spit'.
