A large individual conveniently hiding under a piece of terracotta pot that I left of for them! 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 a mature (~1.35 mm) Group 2 individual. The presence of a sub-anal appendage (SAA) shows it to be a female. It had been thought (not sure how this arose) that the red-backed individuals where invariably male. Definitely not the case.
[Part of a garden survey of the "novel" springtail Katiannidae Genus nov.1 sp. nov. that I'm doing for FransJanssens@www.collembola.org to establish the size and differences between the various instars.

A local Staffordshire churchyard has a thriving colony of these springtails. They seem to congregate on a damp area of wall. They have only recently been reported in the UK and are designated Katiannidae genus nov.1 sp. nov..
As there has been lots of rain, I visited the churchyard this morning to check on numbers. The wall was swarming with them. I did a few shots and when processing them, noticed that there was a spermatophore on this one. I presume that it's been produced by a male of this particular species.

The fluorescence of the "skin" works as backlight for the scales, thus their structure is emphasized.

Not a great picture, but it has rained so much that the springtails have been flushed out the soil! Not a creature I usually get to see, they are so small I usually don't stop to investigate them
We've had our first good rain for ages and ages, and the springtails are out en masse in the water bowls and droplets. There are a couple of species in here, seen best in the middle image.
A globular springtail in our Staffordshire garden this morning. It has the appearance of one of the dark forms of Sminthurinus aureus, but was MUCH larger than any of the "golden" forms that I've ever seen.
A little image dump from our stay in North Wales. The weather was almost perfect which allowed us to make the most of our trip.
A lovely springtail from an amazing woodland on the north coast of the LLyn Peninsula, Nant Gwrtheyrn.

right : Entomobrya multifasciata, the whole year to find in my garden...
This one is Dicyrtomina saundersi it seems. Had other shots but a friend needed this shot of it's backside for a positive ID. On our present trajectory, these are the kinds of creatures that will inherit a wrecked but probably repairable planet from us.
About this time in 2017, I visited an orchard in a walled-garden at a local stately home. I found an unusual Sminthurinus springtail there. It's possible that it's a species new to science and it has been given the designation "Sminthurinus sp.5 Janssens & Phillips 2017".
Today I visited the same site to see if I could find it again. The ground was rather dry and I struggled to find any leaves with springtails underneath. I then found a shaded area that yielded the specimens (1-5) above. Number 6 is an example of sp.5 from last year. Note the lateral and rear pigment patches and the patch with a horizontal line on abd.5. It looks like none of the five samples I found today are the same, although they are all Sminthurinus species. I'll be going back!
I haven't "got my eye in" yet this year, but assume that 1-5 are all forms of Sminthurinus aureus.
Composite, not to scale. Clockwise from top:
Pogonognathellus longicornis, Dicyrtomina minuta, Orchesella cincta.
This piece of Cordyline leaf was frozen to the lawn in our garden this morning, but the springtail seemed happy. I understand that they produce glycerols that act as a natural anti-freeze.
This is a composite of two images, one for the "overall" appearance and one to show the sub-anal appendage (SAA). The presence of this indicates a female.
This is a shot from my garden of a whole bunch of springtails (Collembola) on the surface of the water in a plant pot. They were being moved round by the wind were clambering onto this small piece of wood and on each other.
Can name some but not all of them
Someone's home! I don't think fairies look like this!! :0
