Don't Starve Walkthrough → Dragonfly
During its offensive phase, the boss takes on a fiery hue, damaging everything nearby and setting objects on fire. If left alone for a while, the Dragonfly will calm down and revert to its normal form. Damaging it with a ranged attack will provoke the Dragonfly, dealing area-of-effect damage that slows it down, allowing you to escape.
How to kill her?
It will spit lava at various objects, turning them to ash and consuming the ash. When the Dragon Fly consumes 20 or more Ash, it will go into hibernation. If you get too close during an attack, the monster will enter "heavy mode," setting everything around it on fire. The Frost Staff and Old Bell are also unusable due to the Dragon Fly's ability to quickly defrost. When the player is within range, the boss attacks normally. The Dragon Fly then slams the ground three times, creating a ring of fire that affects everyone (igniting everything with fire and dealing area-of-effect damage during the attack).
The easiest way to kill any boss in Daunt Starv is with Sleep Darts/Pan Flute and Old Bell/Gunpowder. The Dragon requires a stack of 138, which not only instantly kills the mob but also, due to its fire immunity, won't set any dropped loot on fire. The next way to kill the Dragonfly is to throw 20 Ash, which it will immediately fly to and eat. This will put it to sleep, allowing you to place 138 Gunpowder nearby. The Old Bell is only useful if you want to weaken the boss. Place 3-4 Gunpowder in a pile and ring the bell as the Dragonfly approaches, very precisely, so that your large foot steps on it.
If the two strategies above fail, try leading the boss to the Swamp (or run to the swamp when it activates attack mode). Merms move quickly, and the tentacles will deal damage first (before they are hit by an area-of-effect attack). Although the Fly can kill swamp creatures, it will lose a significant amount of health in the process. Each time it kills any hostile monster, the mob enters a calm period, during which it can easily escape.

Important information
During combat with the player, the Dragon Fly, upon reaching 80%, 50%, or 20% health, will retreat to lava pools and spawn lava larvae to attack. If a larva is killed, the boss will become enraged again and engage in combat. The Fly's freeze threshold is also doubled, and quadrupled during its "special attack." If you leave it in a location and run away, it will return after 1 day. If you kill it, it will reappear after 20 days.
