Wisteria - Any ideas what this is?

We have a large wisteria growing over a pergola which flowers well and creates a good canopy of leaves in the summer.

Was out the other day and came across this ‘thing’ hanging from it and never seen it before in the years it has been growing.

Would anyone know what this might be at all and if anything to be worried about?

Many thanks for reading and a Merry Christmas to all.

Ah, simples ha ha, thanks Spruce… 1st time it’s produced a seed pod in years.
