3 pest questions - are they linked?

1. The nasturtiums are in 3 hanging baskets this year, but I've seen massed black speck infestation on the underside of some leaves. I saw this only when removing wilting yellowing leaves, which condition surprised me.
The plants seems healthy, putting on replacement growth, apart from this.

2. Solomon's Seal leaves are being munched wholesale. Another 1st. Today I saw the little sods responsible. These:

3. Raspberry leaves, especially on one French variety, reduced to veins only. No culprit visible.

Are these linked?
What treatment please?

Nasturtiums are usually attacked by blackfly, I plant them next to my veggies so they are eaten and not my veg. Not lost any nasturtiums though, they're pretty resilient. Maybe remove & dispose of the worst infected leaves

Sawfly tend to defoliate I think so could well be that or caterpillars on your raspberries. Quote "Products containing the following chemical ingredients are all effective on Sawflies

Pyrethrum"

Not sure it'd be suitable on fruit, encourage birds & hand pick off as an organic alternative

Thankyou ss - this morning I shook the solomon's seal stems and loads of the blighters fell off. Crushed underfoot.

Nasturtiums - I've been deadheading them. Shall i just let them set seed pods. They're rather like capers and have given me other plants in prev. years when in garden.

Birds come all the time, but the rasps are much affected - never before though.
I see loads of tiny snails on them. There's upward spray-watering going on gently atm. I shunt the sprinkler along every so often. Will this alone see them off perhaps? Otherwise it'll be pyrethrum, fruit permitting. I'll ask Scotsdales.

Many thanks for your input - much appreciated.
