The leaf roll could be from http://agrozoo.ne...s-robiniae
Doh not 100 % sure. There was also a mini spider inside roll.
Any comment to the rest of stuff on leaf ?
If the whitish stuff on the leaf is not part of the leaf itself, it's probably some kind of wax produced by the Auchenorrhyncha nymph. Next to the nymph there's also an exuvia.
