The Meliae belong to a class of sisterhoods whose nature is to appear collectively and who are invoked in the plural, though genealogical myths, especially in Hesiod, give them individual names, such as Melia, "but these are quite clearly secondary and carry no great weight" (Burkert 1985 III.3.2). The Melia thus singled out is one of these daughters of Oceanus. By her brother the river-god Inachus, she became the mother of Io, Phoroneus, Aegialeus or Phegeus, and Philodice. In other stories, she was the mother of Amycus by Poseidon, as the Olympian representative of Oceanus.
Many species of Fraxinus, the ash trees, exude a sugary substance, which the ancient Greeks called μέλι méli, "honey". The species of ash in the mountains of Greece is the Manna-ash (Fraxinus ornus). The Meliae were nurses of the infant Zeus in the Cretan cave of Dikte, according to Callimachus, Hymn to Zeus. They fed him honey.
