Larval stages of the carabid beetle, Carabus (Eucarabus) sternbergi palgongsanensis, were revealed for the first time under the laboratory condition. This beetle had three larval stages and needed of an average 61.4 days from the egg to the adult stage under 16L : 8D at 2$0^{circ}C$. On the feeding habit, though the adults showed somewhat polyphagous, the larvae fed exclusively on earthworms. Morphological features of larvae were described in detail and compared among three instars.
