Other caterpillars would normally shed their skin and heads and leave them behind.

For weeks before they become moths, these insects carry their dead heads, stacking the old head to the current head.

The primary reason for the caterpillars’ head-stacking behaviour is, reportedly, to keep from being eaten.

Thanks, Mr Jit-Leang Foo for the ID

I’m really curious how the stacking process happened, I hope can record this moment in future
