The Larvae life stage has already passed. Once the cutworm is in Pupae form, it is preparing to emerge as a moth.
I would spray or put down a granule labeled for Cutworms immediately . That Pupa stage is only a few weeks long and virtually all cutworm-labeled pesticides will outlast the pupa stage. And anything labeled for cutworms will also be labeled for Moths, so doomsday is coming for that insect, regardless of how protected the cocoon is.
