Flies are small, annoying insects common in the overworld.
These small, winged insects have large red eyes and are half the size of bees.
Naturally attracted to dead and dying things, they can be found chasing and biting zombies nearly to death. Flies can be bred with Rotten Flesh, and on death have a possibility to drop Maggots. Fly Maggots can be used to breed other creatures, like Roadrunners and Capuchin Monkeys, and, in a pinch, used as food, restoring 1 hunger (half one meat icon).
If a fly happens to find itself in the Nether, the diminutive little creature will transform into the monstrous Crimson Mosquito.
Spiders are hostile toward flies.
