Sunset Fireflies are essential to those players that value stealth in The Legend of Zelda: Tears of the Kingdom.
But whether you’re trying to cook up some stealthy elixirs, or you’re finding 10 to give to Pyper for The Flute Player’s Plan quest, here’s how to get your hands on the glowing insects.
Sunset Firefly Location in Zelda: Tears of the Kingdom
Sunset Fireflies are most easily acquired from Beedle, the traveling salesman in Zelda: TOTK in Highland Stable, for 10 Rupees each.

Beedle will be selling his goods at any Stable in Hyrule, as well as occasionally wandering the roads between them, but his inventory changes from location to location.
The Beedle at Highland Stable at the south of Hyrule’s map is the most reliable way to pick up the glowing bugs whenever you need them.

The downside: Beedle can only sell you 3 Sunset Fireflies per day.
However, his shop stock will reset every 24 in-game hours, so you will need to rest at a fire (or sleep in the stable inn) before purchasing more from him.

Sunset Fireflies Spawn Location in Zelda: TOTK
For those who prefer to get their bugs for free, Sunset Fireflies can be found in Pagos Woods, just north of Highland Stable.

Link will need to sneak (press in Left Stick) to get close to the glowing insects and press A to grab them.
Sunset Fireflies will only appear at night, and only when it’s not raining.

Where to Get 10 Sunset Fireflies for The Flute Player’s Plan
For The Flute Player’s Plan sidequest (one needed to unlock all 4 of the Great Fairy Fountains) Link will need 10 Sunset Fireflies to give to Pyper.
The easiest way to get Sunset Fireflies is to buy 3 a day from Beedle at Highland Stable. Alternatively, Sunset Fireflies will be present, free of charge, at night in Pagos Woods.
