I can't see it clearly but it might be a froghopper:
You'll find a small caterpillar inside the 'floss', probably that of a tortrix moth.
My experience is similar to scroggins and I have also never seen one like that.
How about getting hold of more clips and using 8 per pane, 4 each side, on the lowest panes?
And it's difficult to distinguish it from some of the cultivated types of Potentilla. I had a nice red one and was happy when I thought it had self seeded. Until the 'self seeded' ones were yellow... and spread and spread!
Agree with nut but if you mean when is general growth the strongest, then it's probably May. Turn your back and it's weed city!
The first one looks very much like an oriental poppy, which are perennial.
The second is probably a raspberry - they are well known for not staying in one place!
I had the same happen a year or 3 back Baza. I thought it was quite nice having a nest of pollinators in the garden.
I take one in three of the oldest stems out right back to the base each year on mine to keep it under control.
Looks like a young viburnum to me but not sure which one.
Looks like sarcococca (sweet box) and the damage is a classic case of adult vine weevil unfortunately, Helen. I would invest in some vine weevil nematodes and water them in to that area.
