He sails with the Argonauts, is a suitor of Helen, and leads thirty ships to Troy, where Deiphobus kills him. Distinct from Ascalaphus son of Acheron, the underworld orchard-keeper of Persephone.

I.Minyan captains
Homer's Catalogue pairs Ascalaphus and Ialmenus as sons whom Astyoche conceived of Ares in the house of Actor son of Azeus; thirty hollow ships follow them from Orchomenus and Aspledon. Apollodorus and Hyginus count the twins among the Argonauts and Helen's suitors.
In the Iliad he serves among the night-watch captains and stands with Idomeneus at the wall. Deiphobus' spear strikes him through the shoulder; Ares learns late that his son has fallen. His armour later appears among funeral prizes in some notices.
