#there really isn't much in game lore about butterflies but makes me think yknow~

[fly-sky-high-bug-games]

The infection affects all insects, but the effects are the same with butterflies? Radiance created the butterflies. they is more kind with them or much more violent with them?

Hmmm not sure about butterflies but Radiance certainly created (if that’s in a literal term in game lore but not sure) moths, which are a different species of insects but *reads from wikipedia* belong to same classification. 

Details aside, I think Radiance is bound to moths of Hallownest specifically, the whole creation part can be taken with a grain of salt, at least in my opinion. :0 Moths, I feel, would be pardoned if still around in game, unless she considered them traitors of their kind for abandoning or forgetting Radiance. I like to think, because of the Seer, they have a chance to properly speak to her in dreams because it’s “in their blood” due to their origins, culture and ancestry. At least, regarding Hallownest moths.

As for butterflies, there aren’t much in game (and none alive ones :’D) that can help me answer this question. XD I like to say Radiance isn’t picky bug species wise and it’s all about bug’s will and strength of mind that keeps them away from getting infected.

I’ll put some stuff about Silva bellow~

Characterization and story wise, tho, I want to say for Silva (and Alyssum I suppose) that they aren’t any different from other bugs regarding infection. If Radiance can draw them in through memories into endless dreams and control them with it, I don’t think it makes a lot of difference to those who aren’t familiar with how dreams work.

However, Silva has quite a bit of experience with dreams thanks to Taka. While bugs at the mines got infected, Silva stayed the same and it wasn’t just because of her determine, stubborn nature. When ever Silva was to dream “hearing” Radiance or seeing her light, Taka would seal that memory away from her so she wouldn’t remember Radiance upon waking up and succumb to her control in next sleep. He hid this from Silva until recently.

Bonus story tidbit:

In Silva’s attempts to rid of infection from miner’s mind, she tried to bind and seal away Radiance from the individual's mind, drawing goddess’ attention. Her “encounter” with Radiance almost got her infected at some point because she was suddenly considered a treat for being able to “make bugs forget Radiance” in a sense and make them stop dreaming. The goddess used Gambit to draw Silva in control, even if she resisted anything else Radiance threw at her before that. Taka had to interfere using nightmares and, surprisingly, Silva’s seal of binding, locking away all of Silva’s memories so Radiance would leave her alone because she had nothing to grasp for control. It worked but Yonna had to make dives into her mind to unlock them all again...
