Nycaloth

Also known as nycadaemons, nycademons, and sky demons, these fiends were the elite air cavalry in yugoloth armies, swooping down onto enemy flanks and tearing up unsuspecting troops.

They were the lowest of the greater yugoloths and bitterly resented it, constantly scheming to ascend to greater status and prestige. They sometimes did so by binding themselves to the service of powerful humanoid spellcasters, serving as guards and killers, hoping the mages would grant them a portion of their power eventually.
