Last week, before our current cold snap (though we’ve had no snow, it was -8C in the bitter easterly wind today), I was amazed at how many insects I found on and around a black metal fence that borders a local park.

I was initially checking for hoverfly larvae, as I was alerted a couple of years back to the fact that they can often be found on fences and other objects under trees like Sycamore – I think they fall when the leaves fall, then stay on the fence rails gobbling up any aphids that also fall. The four hoverfly larvae I found (shown below the lovely blue-bodied fly) are all from the Syrphus genus (but it’s not possible to identify them to species level), but I was surprised to also find an abundance of Springtails and more than 20 ladybirds, almost all Harlequin. I don’t know why the fence attracted them all – it felt cold to the touch but perhaps the black paint meant the surface was warm when the sun did actually shine.

A spring in its tail?

I’ve been log-diving again, checking under small rotting branches and logs to see what might be seen. Woodlice and slugs, small spiders and snails there were a’plenty but the only creature I found with even a modicum of colour was this little springtail. I think this is Neanura muscorum, an insect which couldn’t be less true to its name if it tried – no tail to be seen and certainly not very springy.

British fungi, British insects, Daldinia concentrica, King Alfred's Cakes, springtail, woodlouse

King Alfred’s been back in the kitchen but a Great British Bake Off winner he is not. His cakes, otherwise known as Daldinia concentrica, even when you can peek inside their blackened exteriors, never look palatable. With these I found in the woods this week though, Alfred has certainly produced some creative shapes.

And, even if inedible, they are sturdy enough to provide a home to tiny creatures, in this case a woodlouse and a springtail.

Just one old fencepost, wood species unknown, but look at the number of lichen species it’s home to, as well as the lichen-loving Springtails. It’s a multifarious microcosm of the wider environment, a miniature landscape of vibrant colour and diverse shapes. Old fenceposts are usually worth a closer look.

Comatricha nigra, Comatricha slime mould, Dicyrtomina saundersi, fungi on rotting wood, Neanura muscorum, slime, slime mould, springtail, Trichia persimilis, Trichia slime mould

Springtails and slime, a colourful combination, currently to be found on and under many old branches and rotting logs, in a saturated woodland near you, right now!

201116 springtails and slime (1)

The orange slime is probably one of the Trichia species, possibly Trichia persimilis, and the white blobs on black sticks are one of the Comatricha species, perhaps Comatricha nigra.

And the springtails? The brownish one with the hairy bottom is likely to be Dicyrtomina saundersi, and the blue-grey-coloured ones may be Neanura muscorum, but my photos are not good enough to make positive identifications.

Hairy snail, slime mould, slugs, springtail, under a log

When wet weather forces a change of plan, sometimes the only thing for it is to head to the woods and turn over some logs, because there’s never nothing to see under a log!

Two slugs, possibly even the same species despite their obvious colour differences.

Eggs? Those on the left might well be slug or snail eggs but the ones on the right were much smaller and seemed caught up in a web or perhaps just strands of slime. I didn’t poke them – didn’t want to disturb them – so I’m not sure of their texture.

200116 5 slime

A slime mould, though not as much slime as I was hoping for. Possibly one of the Trichia species, perhaps Trichia persimilis.

200116 8 springtail

A springtail, probably one of the Entomobrya species but I really needed a photo of its upper side to be able to confirm its identification.

200116 7 hairy snails

Hairy snails (Trochulus hispidus), I believe, as the only other hairy snail has a more conical shell. It always seems odd to me for a snail to have hairs … but odd is good, interesting, never boring!

British hexapods, British springtails, Collembola, Dicyrtoma fusca, Dicyrtomina saundersi, Entomobrya multifasciata, Hexapod, Pogonognathellus flavescens, springtail

No, it wasn’t me sitting on the lichen on the fence posts. If you have keen eyes, you may have been able to spot a tiny creature in that last image I posted. It was a Springtail – not an insect, but a hexapod and, with around 250 species found in Britain, Springtails form the largest group of hexapods, the Collembola.

190106 unidentified springtails (1)

These creatures are tiny – no more than 6mm long, but extremely abundant. They mostly eat rotting leaves and bacteria so, as well as being found amongst the lichen on fence posts, they can also be discovered, in their millions, in the soil, in compost heaps, in fact anywhere there’s rotting vegetation. According to the Naturespot website, it’s estimated there can be as many as 100,000 Springtails in each cubic metre of top soil. (Some species also eat live plants and so are considered pests by farmers and gardeners.)

Pogonognathellus flavescens

Springtails are so named because they have a tail-like appendage (the furcula) under their abdomen. This ‘tail’ is held in place with a latch, which, when they think they’re in danger, they can simply release to catapult themselves into the air and escape.

Dicyrtoma fusca

The Collembola are of two types, the round-ish ones (globular) and long-ish ones (linear), and, as you can see from my photos here, I’ve managed to find some examples of both types.

Entomobrya multifasciata

My fascination with these miniscule creatures has only just begun so I shall probably blog about them again when I’ve found a few more species.

#365DaysWild, British lichen, Cosmeston, Cosmeston Lakes Country Park, lichen on fence post, springtail

Much to the amazement – or perhaps the amusement – of Cosmeston’s dogwalkers, I spent rather a lot of time closely studying the tops of fence posts today. The variety of lichen to be found on them is really quite astonishing but I wasn’t only admiring the lichen. There were even more interesting things sitting on those fence posts …
