Er... I wouldn't want to meet this creature on a dark night. How big do they get?
They may look formidable but they're really gentle, lovely things. And yes, they can grow to an impressive size. The 'Giant Weta', reaching impressive proportions. Sorry, I can't find exact size limits but I'm sure you could find out with a bit of canny search engine use.
Recently, I believe I found one in my kitchen cupboard. I say 'believe' because, at the time I was thinking that it was a grasshopper - a very +BIG+ grasshopper. They're rarely seen in populated areas.
There's many types of wetas. Okay, so anyway, I have cupboards with gaps between the floors, with venting to the outside of the house. It's an old house and I guess the cupboard would've acted as a cooling device. Anyway, through the gaps in the floor between the bottom and the middle cupboard (three stacked one-on-one), I noticed these weird things wiggling and couldn't quite make out what I was looking at. Then, it jumped between the gap and I just went "WTF?". Huge back legs, exactly as in this picture, here.

Although it wasn't as big as the one in the picture. I live in a large city - Christchurch, and that's why my first instinct was 'grasshopper'. But, the thing was huge, relatively speaking, and I have to admit, I didn't go into the cupboard for a couple of days hoping the thing had made its way outside. At least, I hope it has done so because Weta's are quite beautiful, strong, interesting. It must've been around four centimetres long, and then add in the antennae that were wiggling around.
They're held in such high regard, that the animation company that won an academy award for LOTR was called, "Weta Productions", or something similar.
Oops, sorry.., I've taken this somewhat off topic.

There's heaps of pics and information regarding these extraordinary, and quite harmless creatures. At least, harmless to us.
