|The pupa of a medium-sized male C.
caucasus. Here, it has been removed from its protective cell
for photographic purposes. If done very carefully, it can be placed
back into its natural cell unharmed, and there is also a technique for
creating an artificial pupal cell when necessary. This should only
be attempted by very experienced professionals however, as removing a pupa
from its cell can have disasterous consequences when the time comes for
the adult beetle to emerge.
