Kiwi leaf pest concern - any ideas plz

Kiwi (Actinidia) leaf pest concern - any ideas plz on what the bug is? and also what the black sooty moulding areas are.

Maybe the bug is not a pest but its a good guy ??

The kiwi is growing in a tub in a greenhouse. These pests are on the lower leaves that are going a bit mottled in color, with the new leaves being fresh and green.

The below photos were taken through a 30x jewelry glass/loupe.

We have had in past years spider mite on our grapes. But they seem clear so far.
