drawImage() smears image on JPanel but why?

Question

I'm following this tutorial and when I animate my aliens from a PNG image using drawImage() my image smears on the JPanel and I'm not sure why that is, anyone know?

[more description of issue] As I move the image from the right side of the JPanel to the left there is a trace left. It like leaves a trail/footprint... I'm not sure what is causing it...

Here is a pic of what i'm talking about,

Looks like you're not erasing the previous alien before drawing the new one. — Jim Garrison, Sep 05 '12 at 17:11
Thanks I got it to work. But it was because I wasn't calling the super.paint(g) method. I had the background color set in my constructor! — user772401, Sep 05 '12 at 17:21
Your last comment would make a great answer. Please put it as an answer & accept it. Glad you got it sorted. :) — Andrew Thompson, Sep 05 '12 at 17:31

I got it to work. It was because I wasn't calling the super.paint(g) method. I had already set the background color my constructor!
