How would I use the blur filter property

Question

I commented out the alpha line in my script but I would like to use the blur filter property.
My animation seams a bit abrupt an easing effect can that be doe or not ... if so how?
Please take a look at the attached pictures for more detail ... thank you.

var dir:int = 1;
var T:Timer = new Timer(1);
T.addEventListener(TimerEvent.TIMER, flap);
function flap (Event:TimerEvent):void
dragonfly_mc.wings_mc.scaleX += .05 * dir;
if ((dragonfly_mc.wings_mc.scaleX>=1&&dir>0) ||
(dragonfly_mc.wings_mc.scaleX<=.3&&dir<0))
dir*=-1;
//dragonfly_mc.wings_mc.alpha = .3;
//import flash.filters.BlurFilter.quality;
Event.updateAfterEvent();
T.start ();

var dir:int = 1;
var t:Timer = new Timer(1);
//var bf:BlurFilter = new BlurFilter
//(10, 10, BitmapFilterQuality.HIGH);
//var gf:GlowFilter = new GlowFilter
//(10, 10, BitmapFilterQuality.HIGH);
import fl.transitions.Tween;
import fl.transitions.easing.*;
import fl.transitions.TweenEvent;
var blurX:Number = 80;
var blurY:Number = 80;
var bf:BlurFilter = new BlurFilter(blurX,blurY);
var tw:Tween = new Tween(bf,"blurX",None.easeNone,0,30,1,true);
t.addEventListener (TweenEvent.MOTION_CHANGE,f);
function f (e:Event)
bf.blurY = bf.blurX;
dragonfly_mc.wings_mc.filters = [bf];
t.addEventListener (TimerEvent.TIMER, flap);
function flap (Event:TimerEvent):void
dragonfly_mc.wings_mc.scaleX += .05 * dir;
if ((dragonfly_mc.wings_mc.scaleX>=1&&dir>0) ||
(dragonfly_mc.wings_mc.scaleX<=.3&&dir<0))
dir*=-1;
//dragonfly_mc.wings_mc.filters = [bf, gf];
//dragonfly_mc.wings_mc.alpha = .2;
//import flash.filters.BlurFilter.quality;
Event.updateAfterEvent ();
t.start ();
