The Crimson Mirelands is the second large area you'll visit on your journey through Pokemon Legends: Arceus, filled with marshes and swampland to trudge through and Pokemon to find. That's not all though, there are another 20 Wisps here that are part of the Eerie Apparitions in the Night request!
By now you're sure to have realized that Wisps are far more visible if you look for them at night, as you don't have to get close to them to make them appear. Talk to the Galaxy Member at the camp if you want to fast-forward to nighttime. Also, some of these Wisps will require certain Ride Pokemon to acquire, so maybe leave the big hunt until the end of the game.
