Seasprite -
I had quite a few of those when I was very symptomatic. I think mine were a little closer to the surface because they didn't form any significant scabs. Looked like little scratches.
Here's the scary part. I SAW one of these form. It happened right where I was looking (I was treating my skin at the time). It was just like a quick "zip", as though there was something within the uppermost layers of skin that moved quickly causing the tiny "rip".
I know some people have much bigger ones with real scabs.
There was a picture of Amy Winehouse that showed not just the lesions but significant "cat scratches" on her arms. I'm not saying she has Morgellons (though many have said that)...it's not for me to say...but the visual matches.

ps - go here and enlarge the picture toward the bottom where her arm is visible.
