Flies are very common enemies, found on almost every floor. They can also be spawned by various monsters and bosses, including Duke of Flies, The Husk, Hives, Swarmers, Gurdy, and Pestilence. Skatole changes the behavior of all types of flies. The Lord of The Flies transformation converts some types of flies into Blue Flies.

Black Fly
Black flies buzz around the room randomly, often moving away from the player. They cannot damage Isaac at all, even by touch, making them completely harmless. However, they can turn into Pooters if they fly around Poop for too long or come in contact with a golden poop.

Mama Fly
Mama Flies behave like Black Flies movement-wise, but spawn Pustules on the ground. Upon death, it releases Small Maggots.

Attack Fly
Attack Flies are red and black flashing flies that will follow Isaac relentlessly until killed. Their only way of damaging Isaac is by contact, and they move rather slowly, making them easy to kill. However, they can be dangerous when found in groups, as they can swarm around Isaac quickly.

Attack Flies turn into regular Black Flies if Isaac has Skatole. They take a small amount of time to convert into Black Flies, so it is possible for Isaac to be damaged if the player is not careful.

Large Attack Fly
These have the exact same behavior as regular attack flies, and move at the same speed. However, they are larger and have more health than regular Attack Flies.

Dart Fly
Dart Flies are similar to regular attack flies, but attempt to mimic Isaac's movements. Their only way of damaging Isaac is by contact, and they can move fairly quickly, making them potentially dangerous when found in groups.

Swarm Fly
Swarm Flies are similar to regular attack flies, but appear in tightly-packed clusters. Their only way of damaging Isaac is by contact, and although they move fairly slowly, they can be dangerous by simply outnumbering Isaac.

Hush Fly
Hush Flies are spawned by Hush and behave somewhat similarly to Ring Flies, flying as towards Isaac in certain patterns. Unlike Ring Flies, they can form other shapes such as polygons and can also orbit Hush.

Hush Flies have a brief period of invincibility when Hush spawns them, making them appear to have more health than they actually have.

Hush Flies are not affected by the Beelzebub Transformation.

Moter
Moters appear as two Attack Flies joined together. They behave similarly to regular Attack Flies, but split into two Attack Flies upon being killed. Their split is very wide and unpredictable and can easily shave off half a heart. It is recommended to kill faster flies and other small monsters before it as the two flies it spawns are actually more dangerous in many ways. Running between them just as they split is also a very good way to dodge.
 * If Isaac has Skatole, or uses a bomb, killing a Moter will not make them split into two Attack Flies.

Eternal Fly
The Eternal Fly is a white Fly that can be found on any floor in the game. They usually circle Corn Poop or enemies like Holy Leeches and the Hanger and will not stop circling them until their hosts are destroyed. Before that, they will deal damage to Isaac if he touches them and are completely immune to all forms of damage. When their hosts are destroyed, they convert into Attack Flies.
 * If Eternal Flies are circling Corn Poop and there are no other enemies around, you can leave the room at will. This is true even if they have already been converted into large attack flies: they will simply disappear when you return into the room.

Ring Fly
Ring Flies are a new addition to Rebirth. They are pink flies that, upon entering the room, will cluster together into a circular formation and orbit rapidly while moving towards Isaac. They will hold formation even when you destroy all but one fly. The maximum amount of flies per formation is 10. These flies are fast and take up a large amount of space, so it may be recommended to hold these on higher danger priority.
 * Ring Flies are not affected by Strange Attractor and will continue to stay within their current circular formation.

Willo
Willoes are a type of fly, that will form into a circle that orbits Isaac. They will orbit Isaac until killed, and will shoot orange shots at the player occasionally, signaled by them sparking up a bit. These are also spawned by Mullighouls.

Fly Bomb
Fly Bombs fly erratically towards Isaac, and are fairly fast. When killed, they will turn into a miniature bomb, that explodes after a short delay. This miniature bomb behaves like a regular bomb, damaging Isaac and monsters. These can be spawned by Blasters.

Boom Fly
Boom Flies roam around the room diagonally, dealing touch damage and exploding with a large blast radius upon death. Skatole slows them down, but they remain dangerous. They also spawn from blue champion bosses such as Teratoma and Fistula.

Red Boom Fly
Flies around the room diagonally, dealing touch damage and exploding into 6 directional blood shots upon death. Skatole will only slow down their movement.

Drowned Boom Fly
Drowned Boom Flies fly around the room diagonally, dealing contact damage. Upon death, they explode, release 4 blood shots in the cardinal directions, and spawn a Drowned Charger. Occasionally the Drowned Charger will not spawn, and only blood shots will be fired.

If a Drowned Boom Fly dies while over an obstacle or pit, the Drowned Charger will not be spawned.

Dragonfly
Dragonflies are a type of fly that fly in a pattern similar to Boom Flies. However, when killed, instead of exploding, it will release a stream of fire in either the cardinal or diagonal directions, depending on whether their eyes are opened or closed respectively.

Sick Boom Fly
Sick Boom Flies fly in a pattern similar to Boom Flies. However, when killed, it will spawn a large cloud of poison that will hurt Isaac if he touches it.

Level 2 Fly
The Level 2 Fly flies towards Isaac somewhat erratically, dealing contact damage.

Full Fly
The Full Fly behaves similarly to the Level 2 Fly and Red Boom Fly combined, it chases Isaac and explodes into 6 blood shots upon death.

Pooter
The Pooter very slowly wanders around the room to the point where they basically stay put. They shoot one bullet at Isaac. Pooters will not shoot if Isaac wears Skatole.

Fat Fly
The Fat Fly behaves like the Pooter, except it shoots two bullets in a V-shaped pattern. Also does not shoot Isaac with Skatole.

Sucker
The Sucker has a greater amount of health than a regular fly, and slowly moves towards Isaac. Upon death it shoots 4 bullets in all cardinal directions. Suckers are unaffected by Skatole, so they're always hostile.

Despite their simplistic behaviour, Suckers can actually prove rather dangerous in late levels. This is because often times they'll be positioned in areas containing hazards or the player may have familiars that attack the Suckers regardless of the player's intention. As a result, the low health that the Suckers possess can be used to give the player little time to react when they die quickly and shoot their projectiles outwards.

Spit
The Spit looks like a green version of the Sucker, and it shoots one explosive green bullet at the player upon death. The shot behaves exactly like Ipecac. Spits are unaffected by Skatole, so they're always hostile. Like most enemies that possess explosive attacks, Spits can be used to bomb Tinted Rocks or open Secret Rooms.

Ink
Inks are a type of Sucker, that behaves almost identically to a normal Sucker. However, upon death, it will release 4 black ink shots in the diagonal directions, and leave a puddle of black creep.
