Cuckoo's spit???

Question

On some of my plants there is a white foam, which we called the cuckoo's spit for years. Does anyone know how it gets there and what causes it?

Answer 1

The larva of the froghopper insect lives inside....put some on your hand and run your finger through it and you'll find a little soft green insect. When these mature they become brown and jump like frogs.

Answer 2

Yeah, it's got larvae inside, if you take some you see little yellow things inside. :) It's just put there for the larvae and to protect them.

Answer 3

It is the lava of some insect which spurts this stuff out.

Answer 4

It is the lava of an insect, the froghopper I think, it sucks the sap of the plant and foams it up to form a protective mound. It does not really harm the plant.

Answer 5

caused by the spittle bug....

spray it off with the hose....
