Not Darkness like Meraginasu but Dark(A new aliment from one of the flowers). Dark makes the screen darker and you only can really see when close to a target.

And yes by feeding on nectar it gain its abilities sort of like Congalala. The nectar it feeds on has special properties in them. Some of them have powerful toxins(Paralysis, Sleep, Poison, and Dark) in them while others have some flammable material I guess.

On a side note, it seems to also eat honey and possibly combine the honey with the toxins its gained.
