Foam on wattles

[Martin Butterfield <>]

From memory in the UK a similar item (there are few Acacias in the UK) was referred to as frogspit.  Of course it is nothing to do with frogs, but part of the life cycle of aphids or scale insects.

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.
