The connective ligament will not be visible.  I've witnessed this
process several times with monarch butterflies.  It is certainly
possible that the process is different for other species.  You can read
a description of the process in James A. Scott's "Butterflies of North
America" on page 22.
Opler and Krizek's "Butterflies East of the Great Plains" also describes
the process on page 36, but makes no mention of any connective tissues
(ligament) between the pupa and the larval skin.
