Giant fly

The giant fly is an insect that primarily inhabits Earth Kingdom quagmires and is hunted as food by tribesmen of the Foggy Swamp Tribe.

History
After Aang, Katara, and Sokka were invited to a meal at the Foggy Swamp village, they were offered one of these giant flies to eat. Sokka took a big bite out of a roasted giant fly to prove his point that the vision they saw in the swamp were cause by lack of food.

Anatomy
The giant fly is strikingly similar to the fly, but it is much larger in size. Although flies are usually adapted for aerial locomotion, the giant fly has a pair of relatively small wings compared to its body. The first segment of the giant fly is its head, consisting mainly of the antennae, the mouth, and the specimen's compound eyes. The secondary structure is made up of several segments which include the wings and legs.

Trivia

 * It is unknown how these creatures become as large as they do, though it is most likely connected with the environment they are present in. As the Foggy Swamp is home to very little predatory fauna, giant flies are able to live and reproduce with relative ease. The vast amount of liquid substances in the swamplands also allow the flies to eat in abundance, directly affecting their growth and development. Their size may also be an adaptation set to show their dominance over other insect species, and it may be a threatening factor that determines whether or not other creatures will attack them for food or territory.
