Morgai Flies are a pestilent species found in Middle-earth: Shadow of Mordor. They are small, bee-like creatures that can be found protecting their hives throughout Mordor. While they will not attack Talion or the Uruk army on sight, they will become frenzied when their nest is in danger. A prime example of this would be shooting an arrow at their nest, using Azkâr, knocking it off its placement. This will result in scaring away all common Uruk enemies, as well as triggering fear or hate of Nemeses.
With Mordor's predilection for leaving the recently deceased without a grave, Morgai Flies have become a mainstay throughout the region. Their nests can be found hanging anywhere there might be flesh to be had, and any disturbance to these nests sends the insects into a frenzy. When this happens, the malevolent creatures swarm, working in concert with one another, creating a relentless, stinging mass powerful enough to overwhelm even the most heavily-armored Uruk.
The red markings on their back are reminiscent of the blazing Eye of Sauron, suggesting that these creatures are extensions of his dark spirit.
