I have been bitten by the Madexx bug, like many of you, and after I managed to get my very first one, a red one which I named Antares, and after seeing all the pictures and screenshots, I decided I had to have green Madexx!
So I started a a hunt that lasted for the past 5 days.
Here's what I found:
10.1. 16:34 Madexx (red) My first one that I tamed.
26.1. 03:28 Madexx (bronze) My friend was still up herbing, and decided before heading off to bed, to do a last check for me and found bronze. he rang me up to let me know, and I logged back on, tamed and named him Oros, after "or" which means golden, and Oros who is one of the MtG dragons.
27.1 14:00 Madexx (red) A random round netted another red scorpion. A guildie came to get him.
27.1. 22:00 Madexx (bronze) This one I whispered a random hunter who came and tamed it, and we now chat quite regularly about the rares we're after. It's nice to meet new people via rares
28.1. 16:50 Madexx (black) This poor scorpion got attacked just as I swooped down to tame. I wasn't very professional in explaining that I wanted the draenei to stop attacking him. He died, and she said she didn't realize that I wanted him for taming. She was sincerely sorry, but I felt sad since it was the first black I ever saw.
29.1. 19:34 Madexx (red) Again! Another guildie grabbed him.
30.1. 06:41 Madexx (red) Now I was getting tired of it! At such an antisocial time, I only found the server's top huntress in levelrange and not busy, and her exclamation when she saw him coming out of the freezing trap was "Damn he's pretty!" It felt good to have rehomed yet another Madexx. I thought, surely now Karma has to come back.
30.1. 20:40 Madexx (blue) After a long afternoon of camping, I had enough. I logged off, had dinner, did this and that... Logged on later, thought, well, just one round, and blue Madexx was there! I swept down and tamed him. I called him Starlight, but it might only be a temporary name.
So now, I still haven't found my green Madexx. I'm tired of camping, when I come across him by luck, but it might just have been the Karma adding up
I'll keep looking though. I know I'll only be camping Aeonaxx on my druid instead, if not this pretty creature. I'm terrible that way
But reading the forums, I'm not the only one for sure I haven't gotten many screenshots, but here's deathwing, who I saw on two consecutive days, once in the Twilight Highlands and Uldum, and the next morning again in Uldum. he was something I didn't think I'd get to see, so it was a pleasant, although somewhat deadly change of scenery.

I think its cause he knows we are looking so.. he hides.
