Because there is no src, you have no parent type for the datum.

mob/butterfly
    icon = 'npc.dmi'
    icon_state = "butterfly"
    density = 0
    layer = 5
    New()//when it's created
        walk_rand(src,5)

is there anyway to make it so that when the butterfly gets to the end of an area it will go back and not into the other area?

Yes. There are two basic ways to do this.

The first is to create a special area type, and set up its Exit() proc so that the butterfly can't leave:
area/ButterflyRange
  Exit(atom/movable/A)
    if(istype(A,/obj/butterfly))
      return 0   // can't leave!
    return ..()

The other way is for the butterfly's Move() proc to do the checking for it:
obj/butterfly
  var/area/A

  New()
    ..()
    if(isturf(loc)) A=loc.loc
    walk_rand(src,5)

  Move(atom/newloc)
    if(isturf(newloc))
      if(newloc.loc!=A) return 0  // not the same area
    return ..()

There may be reasons to prefer one method over the other.
Hope that helps.
