He was famed for being Heracles' nephew and for helping with some of his Labors, and also for being one of the Argonauts. Through his daughter Leipephilene, he was considered to have fathered the mythic and historic line of the kings of Corinth, ending with Telestes.
As a son of Iphicles, Iolaus was a nephew of Heracles. He often acted as Heracles' charioteer and companion. He was sometimes regarded as Heracles' lover, and the shrine to him in Thebes was a place where male couples worshiped and made vows.
The Theban gymnasium was also named after him, and the Iolaia or Iolaea (Greek: Ιολάεια), an athletic festival consisting of gymnastic and equestrian events, was held yearly in Thebes in his honor. The victors at the Iolaea were crowned with garlands of myrtle.
Iolaus provided essential help to Heracles in his battle against the Hydra, his second labor. Seeing that Heracles was being overwhelmed by the multi-headed monster (the Lernaean Hydra), who grew two heads in place of each one cut off, Iolaus helped by cauterizing each neck as Heracles beheaded it.
Heracles gave his wife, Megara, age thirty three, to Iolaus, then only sixteen years old – ostensibly because the sight of her reminded him of his murder of their three children. They had a daughter, Leipephilene. He was one of the Heraclidae.
Upon Heracles' death, Iolaus lit the funeral pyre. However, according to some mythographers, this was Philoctetes instead. In Sophocles' Philoctetes, Philoctetes was given Herakles' bow and arrow as reward for lighting the funeral pyre. In other versions, it is Poeas.
According to Diodorus Siculus, Iolaus was sent by Heracles to Sardinia, together with nine of the sons that he had with the fifty daughters of Thespius (the Thespiades), to colonize the island, giving rise to the Iolei people .
Iolaus and the Thespians were buried in Sardinia.
Aristotle said that Sardinia had practiced the rite of incubation, which is the liberation ritual of the people who were affected by nightmares and obsessions. These rituals included that the persons suffering from nightmares should sleep next to the tombs of heroes.
Simplicius of Cilicia adds, in the eight books of the Commentaries Aristotle, that "the places where they were deposited and preserved corpses of the nine heroes that Heracles got from the Thespians and who came to Sardinia with the colony of Iolaus, became the famous oracles."

The Lernaean Hydra or Hydra of Lerna (Greek: Λερναῖα Ὕδρα, Lernaîa Hýdra), more often known simply as the Hydra, is a serpentine water monster in Greek and Roman mythology. Its lair was the lake of Lerna in the Argolid, which was also the site of the myth of the Danaïdes. Lerna was reputed to be an entrance to the Underworld, and archaeology has established it as a sacred site older than Mycenaean Argos. In the canonical Hydra myth, the monster is killed by Heracles (Hercules) as the second of his Twelve Labors.According to Hesiod, the Hydra was the offspring of Typhon and Echidna. It had poisonous breath and blood so virulent that even its scent was deadly. The Hydra possessed many heads, the exact number of which varies according to the source. Later versions of the Hydra story add a regeneration feature to the monster: for every head chopped off, the Hydra would regrow two heads. Heracles required the assistance of his cousin Iolaus to cut off all of the monster's heads and burn the neck using sword and fire.List of butterflies of Ghana

In Greek mythology, Protesilaus (; Ancient Greek: Πρωτεσίλᾱος Prōtesilāos) was a hero in the Iliad who was venerated at cult sites in Thessaly and Thrace. Protesilaus was the son of Iphiclus, a "lord of many sheep"; as grandson of the eponymous Phylacos, he was the leader of the Phylaceans. Hyginus surmised that he was originally known as Iolaus—not to be confused with Iolaus, the nephew of Heracles—but was referred to as "Protesilaus" after being the first (πρῶτος, protos) to leap ashore at Troy, and thus the first to die in the war.
