A LONG Gardening Break...

...or yet another "Hiatus on the Homefront"

After yet another gardening break...
and we are almost ready for the growing season...
OK...OK... I know it has gone mid-AUGUST...
but the drought and then the heat held us back.
But, on the other hand, we'll be eating food "out of season"....
when it begins to get expensive in the shops...
So any bloggin' has taken a back seat...

We had a marvellous visit, though, at the start of May, by fellow LPO Refugers...
a reunion for LPO members who have declared their patch of land, or balcony...
as a Refuge LPO....
which visits a different persons refuge each year...
and this year, we had been asked to host the  day...
with lots to see and lots talked about.... a guided walk around the Refuge...
broken around midday by a picnic lunch, plenty eaten... quite a lot drunk...
and then a great Orchid Walk from Susan of Loire Valley Nature in the afternoon.

The Moorhens decided to nest just beside the bridge this year...
having destroyed the patch of yellow iris...
there is only so much bending and destruction of the leaves that a plant can take!!
But the nest was very visible from the bridge and gave a very nice intro to the site...
and, for a change, had local naturalists... whispering!!

At the six egg stage... she finally laid nine.
Five survived through the early days and were split 2 & 3 amongst the adults.

Then Pauline led the group around the meadow using her new chariot!!
The day was nice, weatherwise... and plenty of wildlife seen...
and we even river-dipped...
with a net!

Pauline introducing the visitors to the meadow...
the raised side bar of "The Chariot" can be seen on the right.

Lunch was had.... and on the way to the orchids, we stopped on the 'flatlands' above Chaumassay to see if we could spot the larks that frequent the fields just there... and anything else that would be different from the valley fauna... and were treated to a wonderful exhibition by a male Hen Harrier... both quartering the fields and.... new for me... trying to flush small birds from the treetops.
As there has been a "vole crash" locally, I am presuming that this 'out of the ordinary' behaviour is a little observed method of hunting when times are tight.

The walk proved interesting...with a number of oddities spotted... the best for me, though, was discovering the very strange larva of a Bloody-nosed Beetle [Timarcha tenebricosa] le Crache-sang.... a "Jabba the Hutt" type of critter....
anyway...
here's a load of pictures from the day.



Two views of a male Beautiful Demoiselle [Calopteryx virgo meridionalis] le Caloptéryx vierge méridional...
this is indicated by the fact that the wing colour doesn't quite reach the body...
in C. virgo virgo, it goes from the body almost to the wingtip.

A nice fat Roman or Burgundy or Edible Snail [Helix pomatia] escargot de Bourgogne, or Gros blanc...
and also known as escargot de Champagne....
these are actually really heavy when they get to this size!!
 
Spiderlings of the Garden Spider [Araneus diadematus] l'Épeire diadème...
which carry the same back pattern as the adults.
All orb-web spiders... as well as many other species...
form these dense clusters of newly hatched youngsters for the first few days.

A Woundwort...
most probably Marsh Woundwort [Stachys palustrisÉpiaire des marais...
given the habitat and pattern on the labia....
although hybrids between Marsh and Hedge Woundwort are not uncommon.
We have Hedge Woundwort by the front fence.... and is a lot darker...
this, though, is by the Aigronne.

A "nest" of Peacock caterpillars on a nettle plant
And then the afternoon and orchids...

Susan of Loire Valley Nature giving a talk on the orchids at Chaumassay....
before leading a walk along the road and up through the woods to the right.


Two colour shades of the Monkey Orchid [Orchis simia] Orchis singe...
first, a reasonably normal version...

....then a hypochromatic version.
Hypochromatic means lacking in colour.... and this one is very pale...
but you can see a tinge of pink.

Then it was single file up the hill into the woods.

Where, as mentioned, I discovered the "Jabba the Hutt" larva of a Bloody-nosed Beetle...
they feed on members of the Goosegrass family...
in this case, found on Madder [Rubia peregrina] Garance voyageuse.
And a male Crab Spider [Synema globosum]... named for the female's very spherical abdomen.
This fella is 3 to 4mm from nose to tail...
in fact, his front legs, at 4mm long, make him look much larger.


We also dipped a net in the millstream before lunch and came up with a few goodies...


A caddisfly larva in its sand tube...
possibly one of the Limnephilidae, which tend to build long, straight tubes....
you can just see its front pair of legs... the others hold it in the tube...
and a Water Mite...Hydrachna sp. possibly, as the habitat fits.


A couple of mayfly larvae... type again unknown... an Olive or a Dun of some sort...

And, finally, a Freshwater Shrimp [Gammarus pulex]...
along with a very small spire-shelled water snail.
And so went the day....
In other news...
the moth trap has had two airings per month...
middle and end on the "half-moons" as it cannot compete with a full moon...
and the identified species count is now up to 230 micro and macromoths...
with plenty more unidentified... mainly the micros.

My favourite spider, Argiope, is back with a vengance... they seem to be everywhere in the verger and one in the potager... plus some casually spotted in the meadow...

And the bief [millstream] has been declared out of bounds to fishermen... it has become a nursery for truitelles... baby trout.
More on all this in future posts....

Moth Mondays - The Garden Tiger

MOTH MONDAYS
The Garden Tiger
Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Superfamily: Noctuoidea
Family: Erebidae
Tribe: Arctiini
Genus: Arctia
Species: Arctia caja



Possibly the most recognisable moth, the Garden Tiger [Arctia caja] l'Écaille-Martre can be seen day and night...
and the caterpillars, called woolly bears, are often seen in the open in Autumn.
Woolly bears needn't necessarily be the Garden Tiger...
all the Tigers have hairy caterpillars... and so do some other moths....
notably the Oak Eggar.
The hairs on all these larvae are irritant and can cause skin to blister in extreme cases.


This is a Garden Tiger Moth caterpillar....
 The forewing markings on the adults are quite variable...
but are almost always brown splodges on a white/cream background...
Chinery states that all brown forewings are found.

Seven examples of wing patterning from photos taken here....
the first is almost as per Chinery...
the third is the darkest I've seen....
the seventh is the lightest,

The hindwings are red or orange, occasionally yellow, with black spots....
here they seem more orangey/pale scarlet than any other colourway.
Three examples.....

These are the palest hindwings I have on record... [30/08/2015]
it also has the largest blobs... which are blueish in the centre!
A darker orange this time... [27/08/2012]
with dark black blobs....
the grey on them is a reflection of the flash!
[With the first example.... no flash was used.]
A pale scarlet with a golden fringe and smaller black blobs [27/08/2016]

It has a wingspan of 45 to 65 millimetres
Normally nocturnal, it will fly by day if disturbed.
It is found across the Palearctic.
It loves damp ground and is most frequent in river valleys.
These moths are most common in June to August, in gardens, park, meadows, grasslands, and scrubby areas.
The caterpillars hatch in August, winter semi-underground or in deep leaf-litter and pupate May/June of the following year.
They feed on low growing, non-woody plants.
In recent years another weapon may have been added to their defence armoury...
it has been discovered that some species of Tiger moths can emit sound at frequencies that jam a bat's echo-location.


Sitting pretty!
Next Monday... the Cream-spot Tiger....
