It is possible that the Leafhoppers are Edwardsiana avellanae, unfortunately no notes...
No interactions present.
This one looks like it might be a sawfly larva Mick. Difficult to see just how many prolegs are involved but the overall appearance and the small black eye are reminiscent of a sawfly. Usually just IDed as 'Symphyta'.
Sawfly larvae have many more prolegs than lepidoptera larvae.
Amended to Symphyta...
