Gardening Know How Questions & Answers - https://questions.gardeningknowhow.comI have a Wisteria climbing up a wooden trellis arch, but something is eating it!. Although Pic1 shows some holes in the leaves this is not my main concern. Pics 2 & 3 show the new shoots being completely stripped of new leaves, more of a worry. I can see no signs of any bugs and have sprayed with a general bug killer, to no avail. I live in Scotland. Any suggestions would be gratefully appreciated.

The leaves are stippled looking which is a sign of spider mites. They need a miticide to kill them. The leaves may have turned yellow and dropped off, or just dropped off.
Wisteria frutecens is a host plant for several butterflies and skippers. I had silver spotted skipper caterpillars on my young wisteria and they completely stripped it. The leaves grew back though. I would let them live if that is what you have.
