Here there have been some amazing terrestrials and botanicals recently, so it is hard to decide which one to choose. My January nomination would have gone to Caleana major posted by disalover, but apparently he has used a photo taken by Michael Prideaux, without naming the originator, and not a photo of his own.
So I nominate the colourful Diuris magnifica, posted by JPMC in his thread

I nominate his first photo on the top of his thread but I am unable to repost it here.
