Vapourer, or rusty tussock
Spotted this vapourer moth caterpillar, Orgygia antiqua, on a sanguisorba flower in my garden in Halifax this evening.
Over the years I've found them in the garden in the egg, caterpillar and adult stages. The adult female is flightless (see my post from the 12th of August last year https://calderdale-wildlife.blogspot.com/2018/08/vapourer.html)
The male's erratic flight put some naturalist long ago in mind of someone who had 'taken the vapours' - i.e strong drink - hence the name.

Common Lizard
Came across this yesterday on Rishworth Moor. Steve notified of exact location for which he had no records.

Tulip Tree
The Tulip tree (Liriodendron tulipifera) in Centre Vale park at Todmorden is experiencing the best display of flowers for many a year. I think it was planted in the early 1930's. They are a fast growing species and do not flower as well 'up north' but this hot weather has encouraged it.
The large upright cup of the flower is from the time when this ancient species was pollinated by beetles and before bees had evolved. It was easier for beetles to blunder into a large and upright flower.
Introduced to this country from America about 1630. Called by the early settlers the Canoe tree, as it was the preferred tree for making canoes by Native Americans, being fast growing with a straight trunk.
There are only 2 species in the genus; the other is from the far east and called the Chinese Tulip tree.

Wyke beck seriously polluted.
As announced at the recent meeting, Yorkshire Wildlife Trust has started a project on the streams of the mid-Calder and the HSS has been invited to participate in some of the practical work and also in providing records of wildlife.
Sadly, Yorkshire Wildlife Trust's previous project in the Calder Valley, the Clifton Beck/ Wyke Beck catchment was dealt a serious blow recently. On Saturday13th July we were at the Wyke Beck just upstream of Bailiff Bridge. The beck was grey-white with household drain water and smelled strongly of drains.
It's very annoying because we have known this as a beautiful little trout stream with Kingfishers nesting in the banks. They almost certainly wont be there now.
I reported it on Saturday evening to the EA and got an incident no. 1718487 kindly given to me by an EA official. You can ring their pollution hotline 24 hours a day, 7 days a week. It's easy to find online.
The point we saw the pollution in the Wyke Beck was just north of Victoria Rd., Bailiff Bridge, SE1467925534.
Pond creatures
Can anyone identify these which have just appeared in a muddy pond very recently? Picture not very clear but best I could do.

Nurseryweb spider
Pisaura mirabilis guarding her young today on waste ground in Boothtown. The female carries a silken egg-sac around under her body until the young are nearly ready to emerge, then spins a tent-like nursery in which she sits. When the dozens of young hatch she guards them from the outside of the nursery for a few days until they are ready to make their way in the world.
Notice she has lost a leg in her adventures, probably a fairly recent injury because it has not begun to regenerate. Spiders are able to grow back lost limbs a little at a time with each successive skin moult. A spider this size would moult several times in her life.
With a body of length 12-15mm this is a large and unmistakable spider (the clover flower behind her gives a sense of scale) and the only British species of the genus Pisaura, common in the midlands and the south but with a patchy distribution in the north. Over the moon to find this spectacular beast so close to home!
A mid-summer day dream
I am concerned about the lack of insects and wild bees. Perhaps I'm not observant enough and behind me there are vast populations which play hide and seek when I turn around.
The photo shows Clattinger farm meadows in Wiltshire which we visited recently. It is one of the best wild flower meadows in the country and a joy to walk through, with abundant blue damselflies at every step. But where was the summer sound of buzzing bees and insects; only a few individuals could be seen if hard looked for.
The situation differs little wherever I go. Flower rich fields and flower laden bushes are lacking in any pollinators.
In our wood as soon as July started, it was impossible to work because of the clouds of black flies that formed. I had to resort to a towel draped over my head to keep them at bay. This was the same every year without fail for the whole of July. But now there aren't any. All gone.
Maybe it was all an illusion and nothing but a dream of lying in the grass in Summer and hearing the soporific drone of insects. Now I have woken from that dream I certainly miss them.

Some July finds I'm excited about
Giant Puffball found at Hanson Lane in a very urban garden. Now mostly eaten. It fries beautifully brown and absorbs other flavours.
Wood Tiger moth at Crimsworth Dean
Wood Tiger showing its underwings. I saw my first one the week before at Gibson Mill. I'd never heard of it before! Seen on a butterfly survey with Hardcastle Crags National Trust volunteers.
Willow Warbler nest at Jerusalem Farm. It builds a roofed-over nest with a side entrance similar to its relatives the Chiff-chaff and the Wood Warbler. When we found it last week the adults were busy feeding chicks (Annie brought my attention to them) but the nest was on a steep bank, cleverly built among thick grass with thistles and Dog-rose, making it impossible to check the contents without beating a path up to it. So finding it empty today (we waited about 15 minutes to see if the adults were still feeding,) and no signs of predation I can record it at least as a successful nest with young fledged in the first week of July. I record nest histories for the BTO, but don't find many warbler nests!

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
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.
