The nymph of my dreams?

(28 July 2017) This is her from behind, butt left, head right. The nymph of a small insect, the plant hopper, abundant all over the mountain. Why does it carry two tails of wax?

Nymph, in rest, wax tails down

Life cycles of insects vary widely. Butterflies are born as larva (caterpillars) become a pupae and then emerge in adulthood completely different: as a butterfly. Same with flies. Others, like stick insects are born as a mini version of the adult, as instar number one. After growing for a while it sheds its skin, becomes instar 2 and finally after six to ten stages becomes the similarly looking adult stick insect.
Plant hoppers have the best of both worlds. They grow in stages, as instars, now called nymphs, but each stage change their appearance as well, to end up as mature plant hopper, changing dramatically at each of the five nymph stages. They don’t waste time as a pupae.

They slowly loose their wax tails which are used for protection and to conceal the insect. Adult females still produce wax to protect the eggs.
Plant hoppers have, when they jump, the highest speed in the insect world. Most ambush predators do not target them because of their high speed of escape.

Technique
These creatures are well below ten millimeters body length. Despite being diurnal, they don’t wait for a ‘cheers’ for the photographer. It’s a matter of setting up the tripod, remote control in the hand and hope to catch’em in the ‘act of just being there’. 60 mm macro lens, f/6.3, 1/400, ISO 200. And enough sunscreen: the photographer’s own wax protection.
