Giant fly

Giant flies were monstrous varieties of the mundane order of insects known as flies.

Behavior
All species of giant fly were highly fearful of fire and instinctively avoided it at all cost, as it could easily destroy their wings.

Combat
Giant flies would land upon their prey and bite at their bodies. When engaging an aggressively defensive foe, giant flies tended to jump backwards to escape combat.

Species

 * Bluebottle: A monstrous variety of the mundane bluebottle fly. They rarely attacked living creatures, unless they had open wounds or were covered in blood. This is because they preferred to things such as carrion and ofal. They were also known to be attracted to sweet odors. Those bitten by giant bluebottle flies had a low chance of contracting some form of disease.
 * Horsefly: A monstrous variety of the mundane horsefly, these were the largest species of giant fly. Highly aggressive, they were willing to attack nearly any creature. They had a tuberous mouth from which they drew blood from others.

Habitats
