On holiday this week and trying to make the most of it. Walked through another churchyard today and found one spot with a fair few collembola - plenty of food for them I guess. My wife gets cross waiting for me in the cold and so I never get to spend as long as I'd like trying to get snaps but I have a few more pictures to follow when I have a bit more spare time.

Orchesella celsa, one of the Slender Springtails (Family Entomobryidae), under loose bark on a fallen log
Springtail survey I'm doing for FransJanssens@www.collembola.org to establish the size and differences between the various instars of this Katiannid springtail. Here's a juvenile of 0.45 mm; possibly instar 2.

High magnification Springtail video. Taken with my little sportscam with an industrial c-mount high magnification lens fitted.
sportscam cost £33, Lens cost £30, C mount adapter, M12 ext tube and UV/IR cut filter around £15. Taken in low light with no additional lighting - handheld
A selection of "typical forms" in the garden this morning, but I was attracted by this individual. Typical Group 1 (pale abd.6) but unusual in having a square of orange/red pigment just in fromt of abd.5. ~0.9 mm in length.
[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..

A couple of mature individuals in the garden today. Here's the smaller of the two (~1.25 mm). A Group 2 individual with dark abd.6..
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.

I was looking at the huge Tree Ear Fungus I found and spotted this little Springtail crawling in its folds.
I'm a bit rusty on collembola as I've not shot them since last winter then again I didnt shoot anything during the summer either was a tiny dude approx 0.5mm.
Another trip to the "Katiannid wall" today. I went just after all the heavy rain had finished. The wall was damp and there were hundreds of them! This is the species designated Katiannidae Genus nov.1 sp. nov.; i.e., yet to be ascribed to a genus and species.
The species exhibits marked sexual dimorphism when it comes to pigmentation/colouration. The mature females I've seen are pale with black pigment spots and the mature males display lots of red (like the individual bottom-right). Immature forms are generally speckled orange/yellow and there's a whole range of intermediate forms; gradually getting more colourfully-pigmented through the developing instars.

A juvenile globular springtail photographed in the garden this morning. Length ~0.45 mm.
I'm assuming that this is a juvenile of the "novel" species Katiannidae Genus nov.1 sp. nov. It was photographed in the same area as where I'm seeing adult instars and looks "right". I'm attempting to photograph and measure the various instars of this species; male. female, juvenile, adult.
I've been doing a garden survey looking at this Katiannid springtail for Frans Janssens. Frans is speculating that there are two distinct groups; Group 1 where abd.6 in adults is pale, and Group 2 where abd.6 in adults is dark. We have not been able to find convincing examples of Group 1 males.
I've gone back to some shots of this species that I took in another location (on a wall surrounding a nearby church). I have been speculating that (perhaps) Group 1 males are the occasional ones that have abd.6 paler than abd.5, but with a pale orange/red colouration that covers the dorsal abdomen. I found this shot of a male from March 2016. Perhaps this helps?

During the weekend I was in one of the most preserved floodplain forest. There were a lot of beetles and nice springtails. Most of them I found at home during selection of sieved materials.
Pictures were made ba Canon 5D mark II + 2x extender and 25 mm macro ring.
This is my first attempt to shoot a springtail. The quality is not the best but I was surprised by the beautiful colored scales of this little guy. Tomocerus vulgaris (thanks Frans)
Another very pale individual in the garden today; this one ~1.05 mm. Very similar to the one in the previous post. These are likely to be in the pre-moult phase (see Frans' comment on previous post). Unlike the last one, this individual was very active.
