Due to COVID-19, the resreve remains closed to the public therefore, today’s field meeting is cancelled. The weather is set fair so I hope you can all get out and enjoy some wildlife after the heavy rains of this past week. I will make sure there is an August field meeting that we can all attend safely as the threat from the pandemic eases while out in the open air.
Not deterred by the unsettled weather at the end of June, I planned to start the new month with a walk using footpaths around the village of West Bretton avoiding the Yorkshire Sculpture Park, which remained closed due to the ongoing Covid-19 pandemic. Come the morning of 1st July with a forecast of grey skies and intermittent drizzle I was beginning to have second thoughts. However, the clouds started to thin, albeit slightly, allowing some weak sunshine to filter through coaxing the temperature to slowly lift. So I was soon more hopeful of seeing some wildlife and set off. The conditions underfoot, indeed almost up to waist level in the tall grass, was very wet. Nevertheless, in places there were clouds of ringlet butterflies fluttering carefully amongst a mass of raindrops delicately balanced on narrow leaves shimmering like precious gems. An ephemeral gift of heavy overnight rain.
Other butterflies included a small number of meadow brown, two small tortoiseshell, a single small skipper and good numbers of the caterpillars of peacock butterfly feeding on nettle. During a brief shower towards the end of the walk I shared the shelter of a tall hedgerow with a bumble bee attracted to the flower and pollen of a field rose (Rosa arvensis). So even on this occasion rain didn’t stop play.
Although we’re still in a state of lockdown, easing of restrictions meant that it is possible to travel around a bit more. With this in mind, Hreather and I headed off to Brockadale on the day of the proposed meeting as we weren’t too sure if other members might turn up on the off chance too. Although we didn’t bump into any othe WNS members, we did have a great morning, spent mainly on the slope noted for marbled white butterflies. The weather was very warm, muggy and overcast which meant that butterflies were out but not really on the wing. Within moments of arriving at the slope, we found a marbled white with wings outspread on a thistle. This was followed by a dark-green fritillary also wings oustretched and sunning. Both these were quickly photographed before they had time to move on.
In addition to the super butterflies, there were a great many plants to admire including lots of pyramidal orchids, white bryony, black horehound, knapweed, minionete agrimony and lots of others that were beyond my limited plant knowledge.Birds included whitethroat, yellowhammer, blackcap and willow warbler but no cuckoo, a very scarce bird this year. The site was very busy with dog walkers and families by the time we left, way more folks than normal, probably due to other sites still remaining closed to the public.
Here’s hoping we see you all at the next field meeting in July, although the location may have to change as the RSPB reserves may well be still closed to the public. I will send an email if things chnage and update the website where necessaary
These days I am doing the same local walk so often I can imagine I am cutting a groove in the tarmac along Jerry Clay Lane, Wrenthorpe. This lane is my gateway to a small island of surviving countryside around Brandy Carr and Carr Gate. I guess due to the Covid-19 outbreak the verges along the lane have not been cut back allowing many plants the opportunity and freedom to flower and hopefully seed. In particular the hedges are entwined together with flowering bramble and dog rose (photo attached). In turn they are attracting a wide range of pollinating insects. I wonder if giving wildlife a chance like this will catch on. My first meadow brown and large skipper butterflies of 2020 were seen here on the 31 May. A photo of a large skipper nectaring on an elder bush close to Brandy Carr Road is attached. Also, there appears to be a good emergence of small tortoiseshell butterflies probably resulting from eggs laid this April and early May by the overwintering adults. Certainly the caterpillars feeding on the garden nettle patch at home dispersed some time ago. Astonishingly researchers have found them to travel up to 55 metres from the nearest nettles looking for sites to pupate. Bird sightings along Jerry Clay Lane this week include buzzard, kestrel, great spotted woodpecker, blackcap, whitethroat, yellowhammer, chaffinch and a lapwing has returned after an absence of two weeks.
Further into the walk looking towards Ossett church the yellow sea of oil seed rape has ebbed away exposing ribbons of scented mayweed and poppies around the field edges. The attached photos show the changing landscape on 2 May 2020 and scented mayweed and poppies on 2 June.
Elsewhere in our local park the marsh orchids are flowering. Photo attached. They are most likely to be hybrids. Wakefield is close to the southern limit of the northern marsh orchid and close to the northern limit of the southern marsh orchid and offspring showing characteristics from each species may be expected. Similarly, both species may also hybridise with common spotted orchids. So the jury remains out for another year on trying to positively identify them.
I have been putting the moth trap out quite regularly over the past couple of weeks but each time I go to empty it I find it quite devoid of trappoed moths! Whether it’s the clear cool nights that are causing me bother I just don’t know, but compared to the past couple of years at this time, it’s incredibly quiet. This morning the trap contained only two moths which is about the norm just now; a small magpie and a really beautiful elephant hawk moth, my first for the year. I stuck this handsome lad on a yellow flag iris growing in my small water feature, totally unnatural of course, and done just for art’s sake 🙂
The Corvid-19 outbreak lockdown rules have recently been relaxed. Even so at the moment I continue to be loyal to my local walks all taken within one and half or so miles from home rather than travelling further away. This has now become a very familiar landscape to me, but it is beginning to show signs it is ready to change and leave spring behind. The pristine fresh green tree leaves are now more sombre with many sycamore covered with ‘honeydew’ a sticky substance excreted by feeding aphids. The tiny caterpillars of moths blown in the wind abseil down from the tops of oak trees on fragile silken threads like miniature SAS commandos. All these insects are a timely food source for hungry young birds and their exhausted parents. Similarly, the yellow fields of oil seed rape are fading fast turning their energy to the job of seed production. Even so their narrow field margins remain a refuge for some wildflowers to shine especially flaming red poppies. Photo attached. Elsewhere yellow is intensifying around paddocks full of buttercups and young rabbits.
On the 11 May I reported the progress of the small tortoiseshell butterflies caterpillars that have transformed the garden patch of nettles into their dining room. They continue to devour their host plant leaving only a skeleton. It is a reminder they will soon start to pupate and then emerge to announce a changing of the guards and summer has arrived.
On the 12 April I noticed a small tortoiseshell butterfly egg laying on the garden patch of nettles. These have now hatched and, characteristically, the caterpillars have formed a communal silken web around the uppermost leaves for protection whilst they continue feeding. Six days before, a comma had used the same patch of nettles for egg laying (see reported dated 13 April 2010). Comma eggs are laid singularly and the caterpillar also spins a silk web on the underside of the leaf. At this stage they are less conspicuous than the small tortoiseshell butterfly so I am not too surprised not to have found a caterpillar so far..
On the 14 April while sitting next to the nettles armed with a cuppa and a piece of cake I noticed an orange tip butterfly egg laying on the flower of a garlic mustard sometimes known as jack-by-the-hedge. I was unable to see any eggs without causing damage. However, it appears they are laid singularly. This may be a blessing, because as they grow the caterpillars may be cannibalistic and no doubt more so when food is in short supply.
On 6 May in accordance with the official Coronavirus outbreak advice of stay home stay safe I once again got myself comfortable with a cuppa and another piece of cake next to this tiny and yet action packed patch of nettles. I was soon joined by a small tortoiseshell butterfly. This time I could clearly see her carefully releasing the eggs from her ovipositor on the underside of one of the uppermost leaves. See attached photos. Eggs are normally laid in batches 0f 60 to 100 so I am not sure how many may survive particularly as the caterpillars have very large appetites. So during this very dry spell I have been busy watering the nettle bed to ensure there is a supply of fresh growth for the growing numbers of caterpillars. Not sure this is reflecting too well on my horticultural credentials!
As today would have been the first of our outdoor meetings, Richard and I decided we would spend our one hour walk to Smithy Brook, between Middlestown and Thornhill, recording the species we saw.
After all the glorious sunny weather over the last six weeks, today was disappointingly overcast, breezy and quite cool, however it actually made it easier to stop and identify the plants as no-one else seemed inclined to be out and about.
We counted 59 plant species but only eight birds, as the cooler weather seemed to have dampened their spirits: we usually get skylark, sparrows and various finches and tits along the lane but today we heard chiff-chaff and yellowhammer and watched a buzzard soaring over the fields.
Because of the cooler weather we didn’t see a single butterfly. We would normally see speckled wood along the sunken lane, then peacock, small tortoiseshell and orange tips along the more open stretch.
When we looked closer at the wild flowers, we spotted common vetch alongside the more conspicuous bush vetch and we almost missed a patch of ground ivy, nestling among the grass and herbage on the sunken lane. Over the last few weeks we have watched the countryside changing as the hawthorn hedges turn from fresh green leaf to frothy white blossom, giving off that wonderful musky sweet smell of spring.
Bluebells, white and red campion and Herb Robert were just a few of the species along the lane with wild garlic, white comfrey and yellow flag alongside Smithy Brook. A field dotted with meadow buttercups and the bright yellow of a patch of birdsfoot trefoil add a little brightness to the morning.
Our lockdown local walks have been drenched in warm, sunny spring weather during April with high temperatures more reminiscent of Spain rather than England, Along with alll the spring migrants arriving on these warm fronts, our own native orange tip butterflies seem to have been thriving. They are on the wing in the latter part of April and early May and depend on early flowering plants, such as deandelions and garlic mustard for nectar, and there’s no shortage of these at the moment. So it appears the orange tips wiull have a perfect season and will have chnace to lay plenty of eggs for next year.
We have been getting quite a few orange tips in the garden throughout the last few weeks and if one arrives in the garden at around 5pm, they often stay to roost presenting me with some lovely photo opportunities proving you don’t have to go for for good photo subjects.
Studies increasingly show us that just looking at pleasant landscapes and watching wildlife can significantly improve our personal health and well- being. It is sometimes referred to as Nature’s Health Service especially in terms of helping to manage the stress of modern day life. Therefore, connecting with nature has never been so important as it is at the moment while our normal activities are suspended due to the Covid-19 outbreak.
Fortunately, at a time of great need nature is not in lockdown, indeed its currently on overdrive moving apace receiving a helping hand from a long spell of fine weather. This has been very much in evidence this week during my permitted walks from home, which have taken me around Brandy Carr and Carr Gate. Wildlife sightings have included watching a pair of lapwings busy feeding in a paddock and later seeing them being dive bombed by a swallow. This turned out to be quite innocent as the swallow was swooping down low to collect what appeared to be a small piece of white tissue presumably for nest building? Nearby there is hedgerow containing several mature oak and surprisingly several midland hawthorn. This species flowers before the common hawthorn, also its leaves are less divided and importantly looking closely at the flowers it has two or three stigmas later forming two or three seeds in the berry. The common hawthorn only has a single stigma and only one seed in the berry. Confusingly these two native species hybridise so this is a good time of the year to tell them apart by counting the stigma rather than trying to find the seed in the autumn.
Continuing the walk the oak are clearly in leaf well before the ash. So are we in for a splash and a dry summer as the old country rhyme goes? Also, I noticed one particular oak tree is holding a mass of oak apples, These are caused by the gall wasp, Biorhiza pallida. The eggs are laid in a dormant leaf bud and the tree reacts by producing this apple like growth around the egg and larva. These are not apples you can eat. However, on the plus side insects are vital for pollinating a wide range of blossom. The attached image shows a busy bee helping to ensure there will be a good crop of apples in the garden again this year.
