Original description on Flickr:

Well, here's another giant springtail, this one weighing in at a hefty 11mm, still not the longest, those are often to be found in the Southern forests, where I'm going tomorrow! This one was enormous though. The moss was shaking and birds were flying up, squawking when it was walking about. I'm still finding them tricky to photograph though as they're wide, spiky and fast, but what a lovely challenge. Uchidanurinae are very communal so it's quite easy to find them in tens at a time in the right sorts of places. These will live in paddocks as well as rain forests so they're quite adaptable. Check out more photos in the first comment that Flickr now hide, which is annoying...
