Cucumber Spider


Delighted to find this bright green little orb weaver Araniella cucurbitina or Araniella opisthographa in my garden in Halifax. It's impossible to tell which of the two commonest cucumber spiders this one is without microscopic examination, which I haven't (yet) carried out. I'll keep watching for any roaming males, which are quite different looking, coming to court her.

If you look closely you can just about tell how she is hooked on to her web, which was being buffeted by a strong breeze, by her tiny tarsal claws.

Bee Orchid rescue


A rescue operation took place on March 21st after demolition work began on the disused site adjacent to the old Rose & Crown on Halifax Road Todmorden. There were a lot of interesting plants on this site and I received permission from the site manager to retrieve any plants I wanted before the whole site was demolished. Early in March, a Bee Orchid (which had flowered two years previously) produced a rosette of leaves and Portia, of the Upper Calder Wildlife Network, safely unearthed the plant along with the fungus on which it depends for its growth. The orchid then took up residence on my balcony in a pot with plenty of the original earth and produced its first flower on June 6th. 


The first bud opened on June 6th

Now, at the end of June, the first flowers have faded but the buds higher up the stem continue to open. The entire plant measures 55cm/21.5" high. A number of Common Spotted and hybrid orchids were also rescued from the site and are now safe on Peachysteve's land. Hugh Firman has requested that a wildflower meadow be incorporated into the plans for the new development on the site in which case it may be possible to return the Bee Orchid to its original habitat. It may now be a question of 'watch this space'!


Multiple blooms now but the lower ones are fading

Elephant hawk moth


Newly emerged Elephant Hawk Moth, Deilephila elpenor, in a garden in the centre of Ovenden this evening.
After about three hours in this position the wings are almost fully pumped out.
Photographing one is a minor ambition realised, having only seen them in books before!

Hen Harrier Brood management


Hen Harrier Brood Management

In a few months’ time the outcome of the 2019 Hen Harrier breeding season will be announced. Some people will claim that it has been a good year and others will trumpet the outcome as a great year for Hen Harriers in England. Neither of these claims will be true, nor will they accurately reflect the fact that whatever the number of fledglings actually is this year, the population will remain perilously low for years to come despite the fact that there is sufficient space for c 300 pairs in the northern uplands.

If brood management goes ahead as planned 2019 will not be remembered as a good year for the English Hen Harrier population. It will be remembered, by leading conservation groups, including NERF, and Raptor Workers across the country as the year that Natural England, the English Statutory Nature Conservation Organisation betrayed Hen Harriers to placate the grouse shooting industry. An industry that is, according to Natural England’s own data, largely responsible for the unexplained demise of 72% of Hen Harriers satellite tagged by their own staff. With that knowledge it is not unreasonable to assume that a similar percentage of un-tagged birds ‘disappeared’ under identical circumstances over the same period. It is also clear from press releases issued by RSPB that many of the birds satellite tagged as part of their Hen Harrier Life Project have also suffered the same fate on land managed for grouse shooting.

Natural England’s answer to those facts is the implementation of their flawed policy of Hen Harrier brood management on the basis that it is essential for Hen Harrier conservation and will lead to an increase in the English population. That second assertion may be true during the breeding season but it totally ignores the fact that all of the evidence reveals that persecution is more problematic after the chicks disperse from their breeding grounds. Brood management will do nothing to prevent persecution despite claims to the contrary. Anyone who believes that the entire grouse shooting industry will wholeheartedly welcome an increase in the Hen Harrier population is at best delusional. There are members of the industry who won’t even tolerate the small number of birds that already reside in, or transit through, the uplands at the present time let alone an increased number.

Following the confirmation that brood management has taken place this year NERF fully expects an announcement in due course from Natural England stating how many eggs, or chicks were taken in to the scheme, what the hatching rates were from each clutch, what the fledging rates were and confirmation that the birds were released back onto the moors from which they were removed. The project calls for all of the chicks to be satellite tagged prior to release back to the wild and for reasons of transparency NERF expects to read a prompt press release when the birds either die naturally or ‘disappear’ in circumstances that suggest persecution was the probable cause. The press release should include the location of the last known fix from the satellite tag.

Whilst Natural England has the legal right to undertake brood management, because they licensed themselves to do it. However, there is no right way to do the wrong thing and there is, in NERF’s opinion no justification for pursuing the brood management of Hen Harriers. We often hear the Police say that they cannot arrest their way out of the Hen Harrier persecution problem and in part that may be true. However, it is also true that Government policy should not be influenced by individuals or organisations that rely on criminality for their industry to prosper.

Additionally we need to know how much of the significant cost of brood management is being borne, not by the industry which has created the problem through illegal persecution, but by the British tax payer.

Despite the hype that we can expect at the end of the breeding season, 2019 will not be a good year for Hen Harriers in England.

Tiger beetle mating season is here!


Tiger beetles mating on Erringden Moor (Sunday June 9th 2019)

After a very fruitful walk through Parrock Clough and Broadhead Clough where we saw and heard many birds, we followed the path up to Erringden Moor and were treated to a host of beautifully iridescent Tiger beetles, some alone, many flying around and also a pair mating. With such changeable weather recently we were lucky to enjoy a mostly rain-free day; the Tiger beetles obviously took advantage of the warm sun too!

Galls on Lime

These are nail galls on the leaf of a Lime tree.
They are caused by a mites (Eriophyes lateannulatus) that is only about a tenth of a millimetre in size, which browse on the lower surface of the leaf.

Chemicals in their saliva cause the leaf cells to proliferate, creating these hollow galls.
The mites then move inside them to feed and breed in safety. They have no adverse effect on the tree.

It seems the mite Eriophyes tilliae prefers the Large-Leaved Lime and the galls are longer and pointed, whereas the mite Eriophyes lateannulatus prefers the Small-Leaved Lime and galls are shorter with rounded tips.
Common Lime can have either species of mite.

Ash trees are dying.

This year Ash Dieback (Hymenoscyphus fraxineus) has progressed from killing saplings and into mature trees. I hardly see any mature tree that is not showing dieback or is nearly dead; wherever I go.

In nearby limestone areas where Ash is a major component of the landscape, there will shortly be huge devastation. All the field trees will be gone and the landscape will be laid waste. We have been suitably warned about this and should have been planting field and boundary trees as replacements.  But this isn't happening.

No shortage of new 'woodlands' but trees are out of favour and forgotten.

This wool is alive

The bark of this tree has white waxy woolly areas, which has been secreted as a covering by the Felted Beech Scale insect (Cryptococcus fagisuga). It only inhabits Beech species.

No male insects have ever been found and fertilisation is not required for the offspring (parthenogenesis).

The scale insect makes small incisions and feeds on the soft tissues of the bark but does not cause serious damage to the tree. Damage occurs when the Nectria coccinea fungus spores gain entry to the tree through the feeding holes. This fungus then blocks the tree's vascular system, causing serious injury or death.

Damage was so serious that in 1902 the Rev. Wilks feared that --"Beech is doomed all over the country and the next generation will only know by pictures how gloriously beautiful our forest Beeches have been".

Look out for this often seen woolly covering and think what damage a tiny 1/16" insect can precipitate in such a huge tree.






Matt Grass

Matt Grass--Nardus stricta, does not advertise itself and is easily missed when growing in a meadow. But during flowering its white anthers capture attention.

Female Pied Flycatcher



The mate of the male posted last week. Today seen entering the nestbox.

Not such a great picture but shows her brown and white appearance. She has a bold white patch on each closed wing. Admittedly this might sound like the description of a female Chaffinch, but this small image maybe captures the typical flycatcher shape, 'sweet' face and beak. Noticed the ring?

Beech seedlings

Many people see Beech tree cotyledons and wonder what plant they are. This is because they bear no resemblance to the 'true' leaves which grow a few weeks later.

In this photo you can see the cotyledons (which are not dependent on photosynthesis but use the stored nutrition in the seed for growth) and growing above them the beech leaves we all recognise.

Double Flowered Cuckoo Flower

Sadly we didn't find the Cuckoo Flower today.
It may flower at little later so could still appear.
Here are some pictures taken in 2015.


These aren't the tyical "Double Flowered" variety which has several layers of petals
An entire flower grows from the centre of the other


The grassland along this stretch of Black Brook has changed a lot in the last 12 months.
This was clearly once excellent unimproved grassland but had become rank,
covered in brambles, docks and thistles with a lot of scrub hawthorn and gorse moving in.
Much of that has now gone and cattle have been put on.
Hopefully this grassland will now return to it's former glory
and we may even find it a good Waxcap Fungi site in the Autumn.

A little beauty that returns in spring

These were photographed on 16th May in one of our Upper Calder Valley oakwoods.
It's not all that common in our area but now known in 3 or 4 cloughs, probably more if they are searched carefully, with ears ready for a slightly feeble repetitive little song.


Pied Flycatcher male


Same bird. He visited two boxes trying to get a female interested. 
We saw him mate with her but it was so quick I didn't get a picture. Females are brown and white.
They take readily to nestboxes. Taken with a compact Lumix DMC-TZ60

I saw my first Spotted Flycatchers of the year on the same day! First time I've got them both on the same day for a new season's sightings.

A post from Hugh Firman, Calderdale Council

Public Spaces Protection Orders (PSPO)

Working together to prevent moorland fires - everyone has a part to play

Calderdale Council is working proactively with West Yorkshire Fire and Rescue Service and West Yorkshire Police to prevent moorland fires, but all agencies also depend on the vigilance and care of those who are out and about in our wonderful countryside to play an active part in protecting it.
To take part in the consultation and for more information, see: Moorland Fires and the PDFPublic Spaces Protection Order [PDF 706KB].
The Public Spaces Protection Order (PSPO) replaced the:
This was introduced under the Anti-Social Behaviour, Crime and Policing Act 2014, on 20th October 2017.
If there is evidence of behaviour in a public space that has, or is likely to have:
  • an adverse effect on the quality of life of the community;
  • and the behaviour is persistent / ongoing and not reasonable;
a PSPO can be introduced by the Council. These can include specific behaviour restrictions and/or requirements for people to abide by, on any public space in question.
Note: All anti-social behaviour can be considered for a Public Spaces Protection Order, not just dog or alcohol issues.

Existing Designated Public Place Orders (DPPO) and Dog Control Orders (DCO)

The change to the law came into effect on 20th October 2017. From this time, current DPPO and DCOs were treated as provisions of a PSPO.
Signage for the DPPO and DCOs has been changed to help raise public awareness. The Council will review current orders and consider amending conditions by 20th October 2020. unless extended before this date, the orders will expire.

Halifax Scientific Society Ramble to Widdop Res on Sunday 5th May

We had nine walkers turn up to what was billed as a "tough in places" walk, tussock grass being the main obstacle to comfortable walking.
From the reservoir car park we crossed the road and went north over the moor to reach the line of rocks which mark the Scout.


Crowberry not yet ripe

After eating our packed lunches we retraced our steps partially, then regained the road half way along the reservoir. We walked for a short while along the road away from the car park then returned to the cars along the north shore. This side of the res has a long water channel which holds a colony of toads usually, though none were seen, nor the spawn or tadpoles. Later we saw about six dried road casualties near the car park so the colony does still exist. Earlier in the year some of us saw plenty of frogspawn along the channel.


The heather beetle, Lochmaea suturalis.
Can periodically occur in large numbers and devastate large areas of heather.


Green hairstreak, resting on bilberry


The final total was six Green Hairstreak butterflies,
being nicely photogenic in the cool temperature.


The Millstone Grit rock outcrop is spectacular in places,
including a large rocking stone discovered by one member, ever more to known as "Robinson's Rocker"


Larinioides cornutus, an upland relative of the garden spider, in its silken retreat.


Green-veined White






A Greylag gosling was panicking and stuck in a deep little stream until Annie rescued it. Here it is on the left regaining the safety of its parents and its only other other sibling on the reservoir.
Other birds seen were Common Sandpipers, Little Ringed Plovers, Short-eared Owl, Red Grouse, Kestrel, Willow Warbler, Stonechats, Reed Bunting, Lapwing, Oystercatcher, and the haunting call of  distant Curlews.


Widdop is one of our most scenic reservoirs.
Thanks for the great pictures and identification Julian.

Insect apocalypse

We have all seen Monarch butterflies on TV programmes and the vast numbers that migrate across America. Yet scientists have found their population has fallen by 90% in 20 years, a loss of 900 million individuals.

This is an extract from a New York Times article which is titled

It is a long article but anyone who persists in reading it to the end will be appalled and frightened at what is happening to species throughout the world. E.O. Wilson, the naturalist and prophet of environmental degradation has suggested we are living in the Eremocine, the age of loneliness.

Climate change may play a part in this but a large part is human degradation of ecosystems. Perhaps we should ask our Council to declare "No further loss of species numbers" to complement their "Climate Change Emergency". But I rather sense the former would not gain any traction.

We are on a treadmill and the old Chinese proverb is a warning, 
"He who catches a tiger by the tail can never let go".

Stag



Phil Dyson sent me this of a stag on one of our highest moors. The sheep fence would be no barrier to it. It has shed one antler, and no doubt the other will fall soon. Whether it is a true Red Deer, a Sika, or a hybrid is beyond my experience. A magnificent animal to come across out on the hills in any case. Well done on the editing to make it clear, Phil.

White Holme, 20th April 2019

A walk to White Holme, from Turvin Road, and part way along the drain, brought me my first green hairstreak up here, plus many green tiger beetles, a few emperor moths and lots of peacock butterflies.  I also heard a reeling grasshopper warbler and a merlin flew northwards over.  It was also nice to bump into and chat with a man from Halifax Scientific Society.  I think he was called Pete Smith.

A tree chrysalis

This tree in Nidderdale caught my eye. It was in a field and appeared nearly dead and not worth looking at. But I could see there was something about it that made me climb a fence to have a closer look.

It was an old Rowan that had suffered badly, perhaps from grazing animals eating its bark. This should have made the tree go into terminal decline and as you can see it was well on the way to expiring.

What the Rowan decided to do next is remarkable. It sent aerial roots down through its own decayed trunk, using its own mulch of nutrients to keep alive. The old carapace then burst open and a new tree has appeared with strong multiple roots and stems. The old crown has decayed and fallen over, to be replaced by a lower and younger crown.

The resilience of trees is amazing.
