The Naturalists' Notebook

A packed MNA coach for our visit to Anglesey. Our first blustery location was Cors Erddreiniog the largest of the Anglesey fens. This extensive reserve is located between the small villages of Bryn Teg and Capel Coch and boasts NNR, SSSI, SAC and Ramsar status. This year’s corpse tally rose with dead Common Shrew Sorex araneus and Pygmy Shrew Sorex minutus.

Common Shrew

Large Skipper Ochlodes venata was the only butterfly but plenty of Dragonfly and Damselfly species with Large Red Damselfly Pyrrhosoma nymphula including one female unusually holding it’s wings outstretched like an Emerald Damselfly Lestes sponsa, Blue-tailed Damselfly Ischnura elegans, Southern Hawker Aeshna cyanaea and Four-spotted Chaser Libellula quadrimaculata.

Sea Kale Growing On Cemlyn’s Shingle Bank

After a brief convenience stop at the loos at Penrhos CP it was off to the second venue for today’s coach trip Cemlyn Bay NR. Cemlyn is known mainly as a valuable site for terns with Common Terns, Sandwich Terns and Arctic Terns seen on the breeding colony – unfortunately no sign of the Roseate Tern that the warden noted.

Thanks to Chris Butterworth for help with the species lists and Chris Derri for use of his macro lens when mine had a premature death.

Last Sunday, the 18th June, I assisted Merseyside Biobank who organised a Bioblitz, where various naturalist disciplines meet to record species over a period of twenty four hours. The event was held at Court Hey Park, the home of The National Wildflower Centre.  I agreed to record fungi and lead a foray at the same time. More eyes are most useful. Unfortunately the weather was not kind but eight people joined me and we recorded forty species, a good result for this time of year.

Most notable was Schizophyllum commune (Splitgill) on a fallen Beech trunk. It is found most often in southern Britain but as our climate warms up these species are moving north. Another good find was of an uncommon Bonnet fungus Mycena clavularis at the base of a Yew tree. Kew Herbarium asked me for a specimen but when I went the next day, overnight heavy rain had washed them away.

A separate visit to Calderstones Park in Liverpool produced a large group of twenty five Melanoleuca verrucipes (Warty Cavalier). Last year, a find of only three was sufficiently important to interest Kew Herbarium. This second find and in such quantity could be another sign that our climate is getting warmer.

Another unusual find was of Panus conchatus (Lilac Oysterling) on a fallen Beech tree.

Chris Butterworth, Dave Bryant and I had a hike up through a forestry reserve and across the moors between Cynwyd and Corwen in Denbighshire Wales. At Cynwyd we looked across a stone bridge at the cascading Trystion stream, a tributary of the River Dee (Afon Dyfrdwy) and saw our first Grey Wagtail. As we climbed up the small lane through the village a Nuthatch was calling and Chiffchaff singing.

Wall Pennywort

We found Welsh Poppy Meconopsis cambrica, English Stonecrop Sedum anglicum, plenty of Wall Pennywort Umbilicus rupestris, Slender St John’s Wort Hypericum pulchrum, Fox ‘ n’ Cubs Hieracium aurantiacum, Dog Rose Rosa canina and the Harsh Downy-rose Rosa tomentosa with its furry leaves and cerise red flowers that seem to lighten to more pinky tones on aging. There were some humongous Dryad’s Saddles Polyporus squamosus growing at the base of a couple of Sycamore trees.

Harsh Downy-rose

We ate lunch at a sunny spot on the lane. A few Hoverflies mainly Eristalis sp. with a Xylota segnis and then found our first Garden Chafer Phyllopertha horticola one of many during the day.

We reached the small reservoir where nine Canada Geese were in residence, three Grey Wagtails and a few Siskin. As we continued to climb Mountain Bumblebees Bombus monticola were on the wing along with a White-tailed Bumblebee Bombus lucorum. There were plenty of plants with Greater Stitchwort – Stellaria holostea, Tormentil Potentilla erecta, Crosswort Cruciata laevipes, Heath Bedstraw Galium saxatile, Pignut Conopodium majus, Bird’s-foot Trefoil Lotus corniculatus, Germander Speedwell Veronica chamaedrys, Common Field Speedwell Veronica persica, Heath Speedwell Veronica officinalis, Brooklime Veronica beccabunga, Wood Forget-me-not Myosotis sylvatica, New Zealand Willowherb Epilobium brunnescens and Hard Fern Blechnum spicant. More fungi with Orange Birch Bolete Leccinum versipelle and the first corpse of the day – a European Mole Talpa europaea.

We heard our first Cuckoo, the odd scratchy Whitethroat, a Redstart, singing Willow Warblers, Blackcaps, Chaffinches, Goldcrest and Coal Tits carrying food in their beaks. A further corpse turned out to be a young Coal Tit whose body was covered in Flesh Flies Sarcophagidae sp. as we approached and had also attracted a Beetle Staphylinidae sp.  

More grossness with the aptly named Dog Vomit Slime Mould Fuligo septica on top on a conifer stump.

We found the footpath out onto the moorland heading towards the ruins of Liberty Hall. Only a few butterfly species with Green-veined White Pieris napi and a few Small Heath Coenonympha pamphilus.

Small Heath

An interesting lichen on a fence post turned out to be Usnea florida – the apothecium show branched eyelash cilia.

Usnea florida

A Tree Pipit performed its aerial flight, plenty of Skylarks, the odd Mepit, two male Whinchats, we heard another Cuckoo and the babblings of a Red Grouse. The single spikelets of Hares tail-Cotton Grass Eriophorum vaginatum were swaying in the breeze and Lousewort Pedicularis sylvatica grew in a wet area further down the track. A Ground Beetle Carabidae sp. proved too fast for my lens and the last few miles down into Corwen were too fast for my legs! We had to march through bog and scramble down stone steps in order to catch our bus back into Wrexham and onwards to Chester then the train back into Liverpool.

The planned destination for today’s MNA coach trip was Hutton Roof but it was not to be… Our coach developed a mechanical problem close to Carnforth and we slowly trundled into the Truckhaven services in first gear.Nature is everywhere! so we took the opportunity to have a nose around a grassed area and hedgerow and were not disappointed. A Small Tortoiseshell Aglais urticae and Dingy Skipper Erynnis tages flitted over the grass and I found an Angle Shades Moth Phlogophora meticulosa resting on a leaf.

Plenty of Hoverflies with mating Helophilus pendulus, a few Volucella pellucens and a rather cool Chrysotoxum bicinctum – this distinctive species has two yellow bands, chocolate wing patches and long, forward pointing antennae.

There were a number of Sawflies including the vibrant green Rhogogaster viridis. There must have been a recent hatch as Green Lacewing Chrysopa perla flew up as we walked through a reedy area.

After a short deliberation we decided to change the venue to Leighton Moss RSPB Reserve and took the short drive in a local minibus taxi to the reserve. A group of MNA members led by John Clegg explored the reserve and had singing Cettis Warbler with some members having a glimpse of this skulking reedbed bird.

Margaret Parry spotted an interesting caterpillar. It was an inch long, orange and black covered in fine tufty hairs and feeding on Pussy Willow. Barbara later identified it as the Yellow Tail Euproctis similis. An interesting wigwam built from reeds has been designed by the Leighton Moss warden David Mower for Bearded Tits to nest in. He had a dilemma as Bitterns prefer wet reedbeds whereas the Beardies prefer drier conditions. Luckily they love the wigwams and he now makes 40 a year.

The other group of MNA members led by Dave Bryant headed up to Trowbarrow Quarry and onto Gait Barrows NNR. A female Broad-bodied Chaser Libellula depressa and a number of Common Blue Damselflies Enallagma cyathigerum and Blue-tailed Damselflies Ischnura elegans were zooming around us as we ate lunch in Trowbarrow. I chased after a Cinnabar Moth Tyria jacobaeae which eventually settled and there were a couple of Dingy Skipper Erynnis tages. Plants included Common Rock-rose Helianthemum nummularium, Herb Bennet Geum urbanum, Common Dog Violet Viola riviniana, Wild Strawberry Fragaria vesca and Common Twayblade Orchid Listera ovata. A photographer pointed out a Fly Orchid spike Ophrys insectifera! This mimic Orchid has evolved a flower structure and also produces a pheromone scent in order to attract male digger wasps to pollinate the orchid.

A small pond held Newts and three male Broad-bodied Chasers Libellula depressa were on patrol joined by a female.As we walked along the small lane joining Trowbarrow to Gait Barrows NNR Dave Bryant and Chris Butterworth both had glimpses of a male Pied Flycatcher. Not surprisingly given the recent rain there was some fungi about with three large Dryad’s Saddles Polyporus squamosus, Oyster Mushroom Pleurotus ostreatus, Deer Shield Pluteus cervinus and Birch Woodwart Hypoxylon multiforme.

We hot hoofed along the boardwalk beside Little Hawes Water stopping briefly to view the Bird’s-eye Primrose Primula farinosa – a native pink-flowered perennial herb that is a nationally scarce plant of the northern Pennines; Common Gromwell Lithospermum officinale – a green herbaceous plant with pale yellowish-white flowers and a few flitting Brimstones Gonepteryx rhamni.

We followed the trail onto the famous limestone pavement where rainwater has slowly eroded broad flat blocks (clints) to form a variety of solution features including deep fissures (grikes) and shallow runnels. Gait Barrows has the most diverse flora of any pavement in Britain and we soon found Herb Paris Paris quadrifolia and Angular Solomon’s Seal Polygonatum odoratum. Herb Paris is a plant that was used both in ancient marriage rituals and to guard against witches. Although it is noted to have four oval-shaped leaves we found a few plants with five and six leaves.

Our target species was Britain’s rarest flowering plant the Lady’s-Slipper Orchid Cypripedium calceolus. Victorian plant collectors caused Britain’s population to decline to near extinction. Indeed in 1917 the Lady’s Slipper Orchid was officially declared extinct until in 1930 a botanist found a single plant on a Yorkshire hillside. Natural England has worked closely with Kew Gardens to cross-pollinate this surviving wild plant and attempt to re-introduce it to some of its former flowering sites.

As we continued across the limestone pavement I noticed an orange and black coloured Leaf Beetle then a mating pair that I later identified as Cryptocephalus bipunctatus bipunctatus var. sanguinolentus.

A Garden Warbler heralded our arrival in the meadow area where the hemi-parasitic herbaceous plant Yellow Rattle Rhinanthus minor was doing a great job at restricting grass growth and thereby allowing other species to thrive – Common Spotted Orchids Dactylorhiza fuchsia were joined by Northern Marsh-orchids Dactylorhiza purpurella and Ragged Robin Lychnis flos-cuculi. Chris Butterworth found a Common Frog Rana temporaria and invertebrates included a Sexton Beetle Nicrophorus sp. and Soldier Beetle Cantharis rustica. All too soon it was time to return for our minibuses back to Liverpool.

I have added some pictures by Chris Derri to the post about Woolston Eyes on 14th April, and also a picture of a Sexton Beetle and some moth IDs to the Cabin Hill post on 24th May

Worthington Lakes, owned by United Utilities, are made up of three reservoirs built to supply Wigan with drinking water and are fed by the River Douglas which originates on the moors above Rivington.It was still hot when we arrived at Worthington Lakes from Brockholes and a singing Wren greeted our arrival. Flowering woodland plants included Herb Robert Geranium robertianum, Wood Avens a.k.a. Herb Bennet Geum urbanum, Greater Stitchwort Stellaria holostea and Yellow Pimpernel Lysimachia nemorum. Mike Barrow and Chris Derri found two plant species that were infected by fungus.

The anthers of Red Campion Silene dioica were covered in a black dust caused by the anther smut Microbotryum violaceum. The rust fungi Uromyces muscari had formed yellow patches with reddish brown spots on a Bluebell Hyacinthoides non-scripta leaf. Insects included a Scorpion Fly Panorpa sp. various Hoverflies and good numbers of the Click Beetle Athous haemorrhoidalis. Click Beetles have a special hinge on their thorax, and by arching their body they can create a tension on the hinge, like a coiled spring. When threatened they leap into the air and the tension is released causing a ‘click’sound.

We were unlucky with our target bird species – Mandarin Duck which nest here but did have good views of a pair of Great Crested Grebe with four stripey young.
