No buff tips have actually pupated yet, some have gone black and died, and one or two are still feeding. I feel ready to give up on them. There should be no such thing as a buff tip caterpillar in the middle of November! Luckily I found a small birch by the river with quite a lot of good green leaves. Hopefully they will do alright.
The other lappet has disappeared, but I am quite certain that he has simply moved to some other branch to hibernate and I never saw him go. I will find him soon enough.
Not much else going on. The Jersey tigers are getting bigger, which is good, and they are happy on their potted nettles.
