Removing line bits after using image trace and path finder

[paulinei23625001]

I'm creating a simplified butterfly wing for a project I'm working on. 

I've imported a jpg then used image trace to make a vector with 10 colours.

I now want to create a black line around the outside of the wing.

I've made a copy, filled it with white, added a black stoke then used pathfinder to create the outline. Unfortunately, the result is filled with these speck and short lines. Is there an easy way to remove these

and make a clean outline stoke? Thanks!

Use the group selection tool and click exactly on one of the anchor points of the outer path of it.

Edit > Cut

Select and delete all the leftovers

Edit > Paste in place

That's great! Thank you. Worked a treat. I haven't used the Group selection tool before.
