Back in September 2010 I once hiked up Lion's Head with Sonja and Aleks in the evening (but apparently nowhere near full moon??) and on our way down I spotted a scorpion on the footpath.
I think it was the first one I'd seen in 20 years, and it was a glorious one. About as textbook an exemplar as I could hope to see. According to some pub wisdom it might have been a non-venomous one, judging by its large pincers and relatively small tail. (I wouldn't stake my life on pub wisdoms, though.)
