pests ID needed please!


I'm a bit stupid when it comes to identifying these pests - never had them before.

I'm attaching some photos, in the hope somebody has been there before!

The Rudbeckia was doing so well up until a week ago and most of the leaves are now damaged.

The Hebe has some dried, brown-edged leaves around the outside of the plant mainly and has lost the freshness it had a while ago. same with the 

The rosemary, marjoram, plus some thymes and other smaller shrubs, all have a strange spotty yellow appearance on the leaves.

What's going on?! 

Also, I have been cleaning up those revolting little yellow/green grubs that sit in a little hammock of what looks like spit (!), in the crook of a plant stem, all week - they are everywhere. They hatch into a flying insect I think, but I can't recall the name. Thought they were harmless to plants though?

    The first two are Leaf Miner damage, loads of different types. According to the RHS there is no chemical control available.  The Hebe looks as if its been eaten probably by slugs and snails.

  • Blimey Muddy - that's not good news image Am I best off chucking them out, do you think, before they spread, or do they tend to prefer certain plants over others?

    many thanks for your advice.

    Remove and burn the affected leaves with leaf miners. For the rosemary that could be thrips soapy water spray will help, the others cut out the affected stems, they will all recover with a bit of vigilance.

  • Thanks Dave - will do. Bloomin' pests...
