I seem to have a minuscule black bugs on leaves and flowers on my orchid collection and was wondering if they are something I should be worrying about.
Initially they seemed to be baby fungus gnats, but as I rub them off, they run away slowly, but don't fly.
They look a lot like thrips to me as well. I had them several years ago and was surprised to find out how many different varieties of thrips there are! Mine didn't fly unless really provoked--if I remember correctly they had the habit of letting themselves fall as their defense--but I can be wrong that was a while ago. In any case they are nasty little buggers! There is a lot of good info on the web including http://www.aos.org/Default.aspx?id=141 . Good luck identifying what you have!
