It was running around the stem of a Canna in the greenhouse, threatening eyes!
It was on the warm concrete outside the greenhouse, I think a mature spider. Well camouflaged!
I found mine on a sunny wall on my upstairs terrace, it was running so fast that it was hard to get a good picture, 25th September 2008, Gent, Belgium
It's size was about 6 mm..
caught in the act! Brrrrr...26th September 2008, on a sunny stone bridge, Belgium
A fairly big (10mm) specimen on a cactus pad
With another spider that it caught, its victims stand no chance, so fast does it move
