Spittle Bugs (or Frog Hoppers)

As I was photograohing them, the sky was blue, and I wondered why it was raining? I actually just happened to pick a spot just beneath a family of raintree spittlebugs! 

These white foam blobs are produced by the immatures, or nymphs, of spittlebugs, small insects related to aphids and other true bugs, in the order Hemiptera. Young nymphs blow bubbles with their excretions, and so they live and feed in a glorious soggy huddle. The dripping foam keeps them moist and cool and keeps predators and parasites away.

They suck the sap of a tree through a drinking straw, called a ‘rostrum’ or ‘stylus’. Plant sap is not all that  nutritious, so the bugs have to work through a lot of it to get sufficient proteins. But this Coral Tree doesn’t seem at all the worse for the wear and as I got close to some of the bugs, they would shoot of as if out of a catapult, so I presume they disperse fairly quickly when disturbed so won’t cause too much harm to the host tree.
