The son of the Nemean king Lycurgus and his wife Eurydice, or according to others by Amphithea. His nurse Hypsipyle left him alone for a moment in order to lead the Seven to a nearby spring, and during her absence the boy was killed by a serpent. On this occasion his name was changed into Archemorus, q.v.
The death of Opheltes is depicted on some late vase paintings and reliefs. A second-century sarcophagus, at the Archaeological Museum in Corinth, depicts Opheltes and his nurse Hypsipyle.
