You can see how the skin is practically translucent by this point and the pupa inside is twitching, and then wriggling like crazy whilst it is squeezing that old caterpillar skin down itself. I love watching this happen and realising that those cute little legs and face are nothing but a spent shell to be discarded at the end of the process.
And we're about ready to burst!
Taken from a different angle so it looks like the chrysalis has moved! At first I wondered about those dark marks as I hadn't seen that before.
The old caterpillar skin which just gets flicked away.
Immediately afterwards you can see some of the butterfly features such as antennae, eyes and proboscis but this smooths out over the next hour as the chrysalis shape takes place and the outer skin hardens.
Here it is a while later and then I realised that this chrysalis was a dark form, hence those marks I showed earlier. I have three green ones outside which I'm keeping an eye on, and they all blend in perfectly with their surroundings and this dark one was very well camouflaged here. With my indoor ones I only got one solitary dark chrysalis, but seeing these guys in the wild you realise how important their camouflage is.
I'm sad to say there was no happy ending for this would-be butterfly and I'll tell you about the fate of this one, and feature the other wild ones, in a 'what these creatures face in real life' post, coming shortly.
In case you missed the video I made of an indoor Swallowtail pupating, here it is again. It makes sense of the photos above anyway.
