Land Caddis II: The Sequel

This week’s venture was somewhat different to our usual outings in that it was aimed specifically at one species: the Land Caddis, Enoicyla pusilla, which we had unexpectedly discovered during our visit to this woodland on 26th November last year. We hoped the weather would be kind to us. On the whole it was; the rain held off and it was not too cold. On the other hand, light snow had fallen overnight and the morning was foggy.

Fortunately the snow was not substantial enough to be a problem but everything was sodden. Leaving the car park we set off on the route we took a few months ago, soon arriving at patches of Polytrichum moss. These failed to yield any Snow Fleas but did bring forth several bristletails.

Despite there only being a handful of British species, bristletails are fiendishly difficult to identify to species level. We can say that this one is a Dilta species, but no more.
 
A little further on one of the vacuums was applied to leaf litter lying at the side of the track. And hey presto - three Land Caddis larval cases appeared. The occupants refused to stick their heads out but it was clear what they were. They had roughly doubled in size since our last visit, these being a whopping 3 - 3.5mm long!    

We progressed to the small area of clearfell where the momentous discovery was made in November.

It soon became apparent that the species was still there in very good numbers, each sample containing multiple larvae. They remained steadfastly within their cases though unless they were picked up, the warmth bringing them out of their shells. This gave me an idea. I set my hand-warmer on its lowest setting, stowed it back inside its grey fabric pouch and placed two cases on top of it. Before long one was out and trundling about.

After a few photos I turned the warmer off and allowed it to cool before tipping the larvae back into the undergrowth.
 
Flushed with success we pitched camp and had lunch. Once we were rested and refuelled we decided to retrace our steps slightly to the main path, then followed it westwards, sampling as we went.

Once again, each sample produced several larvae. Eventually it was realised that we were within striking distance of a monad boundary, so we pushed on until we had crossed it then sampled again. Two samples each produced a handful (literally) of larvae.

 A very pleasing result, which expands the known population in this woodland quite significantly. The area we investigated still only represents a small proportion of the total woodland though. I think we may have found a project for next winter!
 
Occupied though we were by our main target, we did allow ourselves to be distracted by some other finds. These included a very handsome rove beetle, Othius punctulatus

Several ladybird species including Larch Ladybird

And a handsome Eyed Ladybird

Common Birds-foot

And Dicranum majus, an attractive moss.

We turned and headed back to the car park feeling very pleased with ourselves. By this time even the weather was making an effort to join in, the clouds parting to give a hint of brightness. An excellent day.

Weather Window

 Wednesday 28^th January 2026, Catherton Common

Managed by Shropshire Wildlife Trust, Catherton Common is a vast area of shrub heathland. We concentrated our visit in the Riddings Gate area of the site. On arrival we were greeted with a strangely unfamilar sight: sunshine!

The ground was frosty and where the sun didn’t reach it remained so all day. But the clear skies and lack of wind made for a pleasant climate, so much so that over the day several outer layers were shed, a novel experience of  late.

Progressing all of about a minute’s walk from the car park, we pitched camp and inspected the vegetation.

Probably the most obvious insects in the copious amount of gorse were 7-spot Ladybirds.

A single Larch Ladybird also emerged from it, accompanied by a Katiannid springtail.

A third, much smaller ladybird was vacuumed from low vegetation - the sub-2mm Red-patched ‘Micro’ Ladybird.

Patches of Polytrichum moss were present across the area. The sheep made sure that they were all rather closely cropped though, not ideal for Snow Fleas. And indeed we didn’t find any. We did find the inevitable Moss Neobisid pseudoscorpion - this one having already sorted itself a springtail lunch.

An equally tiny Moss Lacebug, Acalypta parvula, was also extracted.

Not all the moss was Polytrichum of course. Among many other species was this rather attractive one - Orthotrichum anomalum.

The day continued to be sunny and almost cloud-free, though this young Scots Pine seemed to have attracted one all of its own.

Scots Pine saplings like the one above were scattered thinly across the site. Little emerged from them when examined; most pine-loving species descend in autumn to overwinter at ground level. An exception was this distinctive two-humped spider, Gibbaranea gibbosa, which is typically found in evergreen trees.

Lunch was taken, allowing us to bask in the conditions, which were a very sharp contrast to those at Morville seven days previously. We then continued slowly around the site. More Polytrichum was vacuumed, this time producing a male Common Earwig with deformed forceps. At this  time of year male earwigs are evicted by the females with whom they have been overwintering. The female is due to lay a clutch of eggs and doesn’t want the male around. Evicted males often turn up in gorse, due to its combination of shelter, invertebrate prey and the odd open flower (earwigs are also partial to pollen and nectar). So it was a surprise to extract one not from gorse but from damp, cold Polytrichum instead.

The remainder of the day produced a variety of invertebrate finds, including a Tachporus sp. Rove beetle.

A barkfly, possibly Trioza sp.

A spider, Tibellus oblongus

Two weevils; first a Sitona species

And then Strophosoma melanogrammum, which has acquired the name ‘Mr Baggy Eyes’ due to the shape of its compound eyes, which seem to sag backwards away from its nose, like jellies in a headwind.

photo: John Martin

Late in the day two bugs appeared. Firstly Corizus hyoscyami, sometimes known as the Cinnamon Bug.

photo: Nigel Cane-Honeysett

And finally, after much searching, a single Gorse Shieldbug, basking cryptically in the afternoon sunshine.

We left site with the sky still blue and the sun still shining. By this time the moon had joined it in the heavens. A rare window in a very gloomy period of weather.

Turned Out Nice Again

 Wednesday 21^st January 2026, Morville Hall

Morville Hall is managed by the National Trust but is not generally open to the public. Our trip was to the wider grounds of the estate. We parked next to the church, dedicated to St Gregory the Great.

The weather forecast ahead of the day was grim and unfortunately proved to be entirely accurate! A brief dry spell on arrival soon gave way to rain which persisted for the rest of the day, often rather heavily. The verges around the parking area were planted with snowdrops and Winter Aconites, doing their best to offer some cheer in the wet, gloomy weather.

photo: John Martin

We moved into the adjacent fields, arriving at one which was bordered by a linear pond on one side and the Mor Brook on the other. The brook was doing its best ‘raging torrent’ impression.

A  footbridge had been helpfully installed across the brook, but having given it some thought we decided not to use it…!

The vacuumers got to work and managed to extract some sodden creatures from their sodden surroundings. These included a couple of weevils; Taeniapion urticarium 

photo: John Martin

And a Protapion species.

photo: John Martin

A Red-rumped Ladybird appeared from the rough grass near the pond.

It turned out to be a day for ground beetles, including the attractive Anchomenus dorsalis,

A splendid Violet Ground Beetle, Carabus violaceus,

And an unidentified (to my knowledge) species found in its overwintering cell and carefully replaced again.

The vegetation was inspected for galls, resulting in records for Psylla buxi (on Box)

And Trioza centranthi on valerian.

Fungi seemed appropriate on such a wet day. The application of modern technology (Obsidentify) suggested (with 100% confidence) that this one is Schizophyllum commune (Split Gill).

photo: Liz Roberts

Whist this one is identified as Basidioradulum radula, but with a mere 76% confidence.

photo: Liz Roberts

The moss Grimmia pulvinata also seemed to suit the ambience.

photo: John Martin

We progressed to an even muddier, slippier part of the site whereupon lunch was declared in the middle of the quagmire!

photo: Keith Fowler

As I sat contemplating my sandwiches, a 7-spot Ladybird plodded stoically through the vegetation at my feet.

Lunch over, several participants decided enough was enough and left. The rest of us soldiered on a short while longer but were not far behind them. We trudged off site, through conditions which need no further comment…
