Can't use pathfinder on "placed" Image
So I'm trying to create a butterfly and I want to include a pattern I added using "Place" to only one wing. I'm trying to use pathfinder to do this but it won't work.
This is what the butterfly looks like with the pattern on:

I duplicated the left blue wing outline w/o fill and placed it above the pattern hoping that I could use "Intersect" in the pathfinder to crop it so it is only visible on the top left wing. However, I got this warning:

I'm not sure if it is because the texture isn't vector or what. I hope you were able to understand the problem!
