They had two children: a son, Arcesilaus III, and a daughter, Ladice, who married the Egyptian pharaoh Amasis II.
About 518 BC, Arcesilaus demanded the return of the monarchical power his ancestors had possessed before his father's reform of the Cyrenaean constitution.
Arcesilaus’ supporters received their promised land but they feared a backlash for their actions and ignored the oracle’s advice not to harm the Cyrenaean citizens.
Arcesilaus and his father-in-law were murdered in the Barcaean marketplace by exiled Cyrenaean nobles exacting revenge.
He devised a plan to lure the Barcaeans out of the town based on a false offer to discuss an armistice.
The Barcaeans accepted the offer of ending the hostilities in exchange for a fair sum paid to the Persian king.
While in Egypt, Pheretima contracted a contagious parasitic skin disease, and died in late 515 BC.
Her grandson Battus IV became king, but Cyrenaica became a vassal state of the Persian Empire.
