Spittlebugs: are they pests?

Spittlebugs are fascinating native insects which protect themselves with a foamy fluid similar to spittle - hence the common name. The adult form of spittlebugs are usually known as froghoppers, but it is the nymphs - the juveniles - which make the foamy liquid. In some countries this foam is called 'cuckoo spit' but not here in Australia.

How do spittlebugs make this foam? Why do they make this foam? Are they pests? Should I be worried if I find them in my garden? All these questions and more are answered in this video! I hope you enjoy the video. Please let me know in the comments.
