This Frog hopper has surrounded itself with a protective mass of bubbles. These are excreted as he feeds on the plant, and these insects are sometimes referred to as spittlebugs. If I wrote clickbait headlines, I could say, "Freakish insect blows urine bubbles and hides in them..." The reality is this is a cunning piece of camouflage and one that you can find in every continent but the obvious one. I suppose that is a tribute to its effectiveness.
Built by the caterpillar using her own hair, this exquisite little cage provides a refuge in which the caterpillar suspends herself as she pupates. This may be a lichen-eating moth species in the genus Cyana.
