Original description on Flickr:

Found this chap on a Eucalypt twig in some grass a few weeks ago in Tasmania and it was very obliging, let me do a few stacks and everything! Stacking, when you combine two or more photos of differing focus, is always about choices and compromise. This one was moving slightly, as there was a wind, so getting the antennae in focus and in line with the head proved to be impossible.

Katianna species are one of the most common and diverse globular springtails over here in Australia, apart from Dicyrtominidae. A very pretty little thing. I especially like the mossy colour against the yellow.
