I saw a wasp searching under the overhang on the Summerhouse so went to make sure it wasn't finding a way in. I can do without wasps building a nest in there. No sign of the wasp but did spot a pupa:
I tried searching to identify it but failed so I have no idea whether this is a future moth or butterfly. As the casing has become transparent enough to see some of the wing markings it won't be long before it emerges.
