Thank you for your precious help !

Your first lupinus does look quite sick and I'm afraid I don't know what
the problem is.

However, if they were my plants I wouldn't worry about the other three;
they seem to me to just show a fairly normal amount of insect damage.

It would be unusual to have perfect foliage this late in the season.

Sorry if this is not very helpful.
