Maybe his is a spittle bug,we have those .
we call the egg nests cookoo spit, as they apear the same time as the cookoo birds return,
spittle bugs or frog hoppers come from the spit looking nests above , the original one looks like someone cut the tip off a pea pod lol. it looks more like a mini moth (it isnt i know, just sayin), but i think were looking at two differant species, i dont think the top one comes from the spittle stuff.
the OP's pic l;ooks more like a mothish looking thing, note the strait edges of the wings. the cookoo spit things are more like thrips
