Foam on wattles

[Harvey Perkins <>]

Unfortunately for us, they decided to spittle up our mint in the back yard this year - somewhat off-putting. Fortunately, we've got lots of mint so there's been plenty that we can still use. It must be a good year for them!

Apparently usually produced by the nymphs of a group of bugs known as spittlebugs or froghoppers. The nymphs use the foam to protect them from predators and provide some protection from temperature extremes. Can be found on many native and exotic species - I've noticed it on grevilleas and weeds along the Murrumbidgee

Anyone know what this foam is - what produces it? I've seen it on wattles in a couple of places recently. This photo was taken yesterday in the gardens around Parliament House - there were quite a number of these bits of foam on several wattles - and I noticed the same foam a couple of days previously on some wattles growing beside the Sutton Road off ramp from the Federal Highway.
