Plague Swarm
From Warhammer 40k - Lexicanum
A Plague Swarm is a form of Daemonic force of Nurgle made manifest. They have the appearance of a swarm of horribly mutated insects and can come in almost any size.[1]
Those around a swarm feel insects under their skin and hear the constant drone of the flies. Their very nature as a swarm makes them highly dangerous to unprepared foes unable to burn or purify the creature.[1]
