Globular springtail X4. Focus stacked using zerene. Taken handheld using a 4X microscope lens on a sony mirrorless body. The springtail is carrying some nematodes
One from today. I've been seeing this form in the garden for a few days but haven't managed decent shots before. This one paused sufficiently for me to get several shots. I've blended elements from each shot to produce this composite.
This (to me) is a "classic" Group 1 mature (~1.25mm) form. It has a dark pigmentation pattern on the abdomen with abd.6 non-pigmented. The abdomen also has little orange/red pigmentation. The head however, does have orange pigmentation. Occasionally I see very darkly pigmented forms (see yesterday's image for example) that do not have any orange pigmentation of the head (except perhaps for a small dot). Group 1 and Group 2 forms usually do though.
[Part of a garden survey of the "novel" springtail Katiannidae Genus nov.1 sp. nov. that I'm doing with FransJanssens@www.collembola.org initially, to establish the size and differences between sexes and the various instars. As a result of the initial findings, Frans is suggesting that there are two distinct groups:
Group 1 - where abd.6 in adults is pale and there is little red pigmentation along the dorsal surface of the abdomen, and
Group 2 - where abd.6 in adults is dark and there is (sometimes) significant red pigmentation along the dorsal surface of the abdomen..

Taking a globular springtail for a walk. Focus stacked using zerene but I cheated and merged a picture of another springtail taken at higher mag. You can see the proper size dufference here www.flickr.com/photos/lordv/11167726253/
A trip to Swell Wood this morning to test out my new flash and diffuser on some of the resident critters.
A grain of sugar for size comparison ,it also helped to slow him down , he kinda liked it.
First time iv'e wrote on a sugar crystal.
As soon as I saw this one I knew it was a big one! It's approaching 1.5mm. I guessed too that it was a female. I tried to get a lateral shot that might show the sub-anal appendage. I think it's just visible.
Frans is speculating that there may be two distinct groups; Group 1 where abd.6 in adults is pale, and Group 2 where abd.6 in adults is dark. This is the largest Group B individual that I've seen so far.

Globular springtail on compost bin lid. Focus stacked using zerene. About 1.3mm body length. Dicyrtomina saundersi
In the recent snowy weather I thought I'd see how the Globular Springtails were faring and turned over a few rocks in my garden. To my surprise there were still lots of springtails attached to the underside of the rocks, many partially set into the ice. As the light reached them they slowly started to move and these two shots are of a couple of individuals wandering around the ice.
