Bush and creepy id help

Good morning folks
Wondered if anyone can help with some identifications. I have a smallish leafy bush (pic attached) possibly a willow? The thing that bothers me is the small white insect that is congrating on the under branches, from a glance it looks like something scaley but closer up some of them are definitely moving yuk!white fly?
Last picture just an interest not an issue yet fingers crossed. A small green insect no wings black eye and red at the back
may be a young greenfly?

 

Your dwarf weeping tree is a very healthy Salix caprea 'Kilmarnock'...common name Kilmarnock willow.

 

The insect looks like a young frog hopper see here for pictures and info on life cycle What are those frothy white bubbles on the plants? | Wildlife Insight

 

Thank you it does look nice and healthy on the outside. It's the crawly inside that bothers me. The small white invaders are quite possibly mealybugs iv given them a shot of washing up liquid for now. I noticed them last year too they make my skin crawl I'm ok with a few insects but the infected branches look like they could go for a walk themselves!

 

I definitely have the frothy white bubbles about so will keep a look out for frog hoppers. Have always wondered about the frothy white 'spits' since I was a kid and now I know ️
