www.invertcare.net has a lot of info. But they are a little bit too general. They also don't cover rare species and some on their list has no info but I think they put it on the list because they will cover it in the future.Hope it helps
Here is one I've found good info from, and I've allso talked to Jan Ove Rein who created the sight on a few occations. Visit http://www.ub.ntnu.no/scorpion-files/ I recomend this sight, he has set up several links to various sights of interest as well.
