startDrag with AS3

I'll get over it, but could use some help; here's what I am trying to do. I have an image of a bee, it's an instance on stage (ins_bee), I simply want to use it as a mouse pointer, but cannot seem to identify the bounds correctly:

import flash.events.MouseEvent;
Mouse.hide();
stage.addEventListener(MouseEvent.MOUSE_MOVE,moveBee);
function moveBee(e:MouseEvent):void {
this.ins_bee.startDrag(true, ***need help here***);
}
