Identity Chrysalis

It looks like a butterfly one, but I think the hole in the side means something crawled in or out & therefore it isn't going to become anything. A lot of caterpillars end up as food for fly & wasp species. Sorry.

Interesting...thank you. If it changes at all I'll put another pic up

That's a shame!

I binged "Chrysalide with a hole in the side" & found this item in an American book about the Rocky Mountains & a Comma butterfly, there was this quote

"Harris states that "great numbers of the chrysalides are annually destroyed by little maggots within them, which, in time, are transformed into tiny four-winged flies, (Pteromalus vanessae) which make their escape by eating little holes through the sides of the chrysalis".

It's not the same species, but predation by flies is quite common.

EDIT : Actually it could be that yours is a Comma butterfly too!! See here https://www.ukbutterflies.co.uk/species.php?species=c-album

Very interesting...thank you
