It's funny. I did not know that I could catch a butterfly in this game. Then, one time I am picking a flower and I get some wings. That made me curious. Now, I have to use the Slow Time spell to catch the darn things.
Hehe, at first they are hard to catch, becasue i thought they were reacting to my presence. In a way i guess they are, but i find that they quickly nestle on a nearby plant or object. Similar with Hawks, they can nestle up on high tree branches.
Trying to catch them in 1st person can make me dizzy

I have tried 3rd person & seems to help.
