Come on, it's not like it's big... it looks big with it's legs spread (it'd be about 15 cm this way), but the body is only 2 cm long. But it's not the prettiest thing you'll come across, I'll give you that!
It's not the worst thing I've found in my room, though. Where I live, I have to check my shoes for scorpions in the morning (even though I'm on a 5th floor), and it's not uncommon to see a gecko running across the ceiling.
No, it's not as bad as it seems; I haven't found a scorpion in my house in over 7 years, but it's better to be safe! And the opilion probably got lost, as I never find them inside. I do see a few of them in the backyard, so it might just have been looking for a warm place to hunt.
Any cool macros with your new cam? Most of my macros are shot with a macro lens adapted to my camera, hence the detail in the closeup (I just resized those pics for the web, the pics are about 3x bigger than that)
Looking forward to looking at more pics!
