The early purple orchids were in full bloom at Brockadale today, in the woods as well as the meadows. I also had a raven fly over.

Butterflies at Engine Wood, Nostell Priory
On the edge of a large nettle bed close to Engine Wood I watched a male small tortoiseshell butterfly establish a courtship territory. It was basking in the morning sunshine and suddenly taking flight high into the sky to investigate every passing small tortoiseshell butterfly. Other males were chased away before eventually, a female was attracted back to the nettle bed where I managed to take the image below. It appears mating takes place well inside the nettle bed and afterwards the female goes off in search of suitable nettles to lay her eggs. Sadly, nettles are often cleared away as part of clean ups in the garden and countryside. My encounter shows how valuable nettles are to wildlife. Indeed, they are vital food plants for the caterpillars of small tortoiseshell, peacock, comma and red admiral butterflies. The other image is of a roosting male orange tip butterfly that I found earlier in the morning
Sunshine and showers at the Yorkshire Sculpture Park
Today, braving the cold wintery showers with occasional sunshine, a walk around the lakes and woodland at the Yorkshire Sculpture Park was rewarded with some wonderful wildlife sightings, including two stoats at first oblivious to my presence whilst chasing each other along a woodland path. Birds included kestrel, goosander and grey heron high up in their nests feeding their fast developing young. Just like me, a male tufted duck had no alternative but to sit out a passing heavy shower of sleet. In contrast, and only a start time afterwards, the sun appeared attracting orange tip and green-veined white butterflies to the woodland glades. I managed a photo of green-veined white on bluebells while other woodland flowers included wood-sorrel and yellow archangel.
Alder Leaf Beetle at Fitzwilliam
I was walking around Fitzwilliam Country Park this afternoon when I spotted lots of metallic black/blue beetles on the leaves of an alder. I think the alder is Italian alder (Alnus cordata).
I believe that the beetles are Alder Leaf Beetle. This species has been absent from the UK for about 60 years and it began to be recorded again in about 2004. It is likely that it was reintroduced to the British Isles by the plant trade.
There were many beetles on this and other trees, singles and mating pairs. You can see holes in the leaf in the picture above. This species causes significant damage to alder and can reduce leaves to skeletons. It was recorded at RSPB Old Moor in 2012 and it has been recorded at Wintersett since 2013.
The weather has been a bit cool but I have put out the moth trap on a couple of nights this week. There was a threat of some overnight drizzle, so I used my usual arrangement of a tripod and umbrella to protect the mercury vapour bulb, which might shatter if exposed to rain.
The catch was much lower than I would expect on a summer night, only two moths on each occasion. The first night produced early grey and a male muslin moth. The second night gave another early grey and a powdered quaker.
All of the three are common but it was the first time that I had caught powdered quaker in my garden. This brings the total number of macro-moths found in the garden to 89 but I think there is further to go because I regularly log new species.
Wormstall Woods, Ledsham – Wildflower walk
A chill wind caught us as we walked up the sloping track brightened by dog’s-mercury, cuckoo pint, white dead-nettle and a clump of hairy violet. We stopped to admire clumps of goldilocks buttercups amongst the celandine, up in the woodland we began to focus on tiny common dog violets with their pale, notched spur nestling amongst the dried autumn leaves.
Climbing up the path further into the woodland early dog violet, with its dark unnotched spur became more prevalent among large patches of anemone, their flowers closed waiting for the sun to come through. Early purple orchid was well in flower alongside sanicle and bluebells. Bushes of spurge laurel had finished flowering. We carried on through the wood until we came to a stile to take us back down onto the footpath through the meadow, the sun was out by this time and orange-tip, peacock and tortoiseshell butterflies enjoyed the ground ivy, red dead-nettle and celandine on the edge of the woodland, with a variety of bees including bee fly. Walking back towards the track we saw butterbur, shepherd’s purse, slender speedwell, germander speedwell, wood speedwell and crosswort……a good morning’s walk.
As the sun was warming up nicely we decided to take a look on the other side of the road at Ledsham vale and were well rewarded by the beautiful pasque flower in full bloom, the best we had seen it for many a year.
A walk to Newmillerdam
We had a walk from our house in Ryhill to Newmillerdam in the superb spring sunshine going via Haw Park and the Walton Canal. Grass snakes have been seen regularly along the canal of late but we weren’t lucky enough to come across one thought there were plenty of butterflies such as orange tip, brimstone and speckled wood.
The bluebells at Newmillerdam were really just coming into bloom and are looking excellent at the top end of the country park. It’s interesting to see the rangers have completely cleared Newmillerdam of all rhodedenrons so there are some large bare areas but, given a couple of years, these will revert to the natural understorey.
This year’s clutch was completed with the laying of a fourth egg just after 3 a.m. on 1st April. The birds have, therefore, been incubating for a little over two weeks and they are well into their usual routine. The female incubates throughout the night and the male takes over for an hour or two early in the day. He usually returns to do another shift – often lasting 2 to 4 hours – in the afternoon.
Peregrines begin incubation with the laying of the penultimate egg, which was on Wednesday, 29th March. Last year, the first hatching was 34 days after the laying of the third egg. Using this as a guide, I would expect the first hatching this year to be on Tuesday, 2nd May. Factors such as the outside temperature can affect incubation time, so this date is only a guide and hatching could begin a day or two either side of this date.
The first three eggs should hatch very close to each other and the fourth egg should hatch a couple of days later.
Morels at Stanley
It’s the time of year for morel mushrooms to appear but they can be hard to find. They are significantly less common in the north-east of England than in some southern counties and they are more numerous in some years than others. It was pleasing, therefore, to hear a report of some interesting mushrooms appearing amongst some bark mulch in the garden of a house at Stanley.
When a couple of us investigated, we found two species emerging from amongst the wood chips. We saw several black morels, which we decided were Morchella elata, but we have since been informed that this name is out of date and they should now be called Morchella importuna. One of the morels was different from the others and we decided that this was the true or common morel, M esculenta, but the best information that we have at the moment is that this is of the same species as the others. I understand that the exact number of species of morel has not been agreed by all and the relationships between the different morels are being studied using DNA analysis. Colour can’t be relied upon for identification.
Morels are sought after by mushroom enthusiasts because they are considered to be delicacies. They are picked in many countries and they are often dried and stored to be eaten later. Having said this, there are some very toxic lookalikes and you must be warned against trying to identify any edible fungi by using information from an article such as this. Always get an expert to identify anything that you intend to eat.
During a walk at Howell Wood, South Kirby, I found masses of opposite-leaved golden saxifrage (Chrysosplenium oppositifolium) in flower along the banks of a stream.
This is an attractive and common plant but it isn’t as well known as some of the other spring flowers.
Lots of chiffchaffs are now singing in local woods. I heard blackcaps in Seckar Wood at the weekend and they have been singing at Stanley Ferry Flash today. An interesting sighting reported today by Mark Archer is a little ringed plover on the new balancing pond at Stanley Ferry.
