In my flowers

It all started by my hollyhock getting eaten by lavare, so it appears to be and I found some green slender larvae crawling round my plants on the balcony. I just left them alone, to do what they were doing.
And now they look like this and in the picture you can see the rest of the fine spin the larva made before it went from green soft larva into this dark pupa.
I do not know which species it is, but on the larvae themselves, they resemble the larvae of Angle shades ( Phlogophora meticulosa).

The larvae at my balcony are (was) similar to that of image 32:

The caterpillar seems to be in quite excellent condition, hanging nicely from my Bacopa and from time to time, the pupa is moving, wriggling from side to side.
I have a similar pupa in my clover and in a cornflower.
Right now I am considering what to do if it turns out they are still hanging there when winter comes and how best to protect them so they get through the winter okay. I think they are in a slightly exposed location and not that protected from wind and weather, but where to put them, without disturbing them.......
And that is, without interfering with nature or at least keeping this interfering to an absolute minimum.
My mother has a very used nesting box on the balcony, with repeatedly chicks every year, this summer, a dead chick kind of blocked the access to the nestbox, so we removed it, without touching the nest box, for the sake of the remaining chicks. Now these have left the nest, but one of them has lighter plumage and is a bit smaller than the others, the feathers looks a bit weird. My mon feels sorry for it and so do I, but we will not interfere, fortunately this little one can and will fight for the food, she gives them, but otherwise it has to fend for itself. If it is a weak individual, maybe even with a gene defect, nature does not help them, but only to ensure a strong and healthy population - neither should we, if it means a life in captivity. This little bird, however, is not entirely without help, it has a relatively safe place to be, some safety from predators and the weather, where food and water always are available, giving it a chance at life, on equal terms with all the other chicks.
