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 palustris]  Épiaire 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....

A nice Spring day

We have a nice start to the Spring today, after some of the "drear" we've had this week....

Last night the Wikileaks were around... possibly in the meadow... for those that don't know us, the Wikileaks are Stone Curlews [Burhinus oedicnemus] Oedicnème criard...
their call sounds like "wikileaks...wikileaks...wikileaks"!

Today, in the warmth....19 Centigrade.... the Brimstones [Gonepteryx rahmni] le Citron and other butterflies were all around us...
male [probably] Mason Bees [Osmia rufa] l'Osmie were hanging around in front of the insect hotel...
Pauline sat deafened by one of the Wrens [Troglodytes troglodytes] Troglodyte mignon...
it ignored her presence and pumped itself up into a frenzy of song.

Wall lizards were out in force... and to cap it all on the reptile front...
a Viperine Snake [Natrix maura] Coulevre vipérene was soaking up the warmth on the barn door!!

I decided, given the warmth, to set up the moth trap....
even though the moon is almost full I will catch something....
on my way back to the house from turning it on... I saw a bat...
so sat with the bat detector on my lap, my back warmed by the house wall...
a useful ten minutes...
Common, Kuhls and Nathius's Pipistrelles all registered as top bat choice....
as did a Lesser Horseshoe!!

Have You Seen This Butterfly?

Birdguides received news early this week that an unprecedented invasion of Scarce Tortoiseshell (also known as Yellow-legged Tortoiseshell) nymphalis xanthomelas La Vanesse du saule or Tortue à pattes jaunes  was taking place in the Netherlands — a country which had never previously recorded this eastern European species. There was until this week only one British record of this species, in 1953. Already a handful of new records has been confirmed in Norfolk, Suffolk and Essex.

They're coming - are they on their way here? They are unknown in France too. My pocket guide describes them as preferring valley bottoms and willows - we've got plenty of those! All photos courtesy of Wikimedia Commons.

The Scarce Tortoiseshell is sometimes referred to as the Large Tortoiseshell. The latter name now belongs to Nymphalis Polychloros, which looks very similar, but has brown legs, hence its other name Black-Legged Tortoiseshell (er...). This species is native to Western Europe and we occasionally see them here.

As you see, they look very similar!

Darwin Syndrome

There is a website dedicated to people who have done idiotic things and have died in the process... The Darwin Awards...    [this Video is the 2012 winner].  
But today I found a Peacock butterfly caterpillar that deserves it's place in the Darwin Awards record....

Most choose sensible places to hang around for the pupal stage... like these.

Tucked safely away behind a spider's web...

But occasionally the brain-cell must have "gone fishing".... look at this fellow...

This is the start of the process... yesterday.
Look at the top right... it should show where it has hung itself.

Yes... it has attached itself to a petal on a Pelargonium
A down-to-earth move!

He's going to drop off soon!

But all is immaterial... look closer at the above picture of the pupa and you will see that he's got visitors.

Two small parasitic wasps looking for a soft spot!
The old skin is bunched up at the top.

Even the one that was behind the spider's web isn't safe....

The ovipositor is indicated by the red arrow.
This is the caterpillar on the right of the first photo.


Susan of Days on the Claise and Loire Valley Nature will probably be able to furnish the name of the wasp and I'll update the entry from her comment.

This is the email that Susan sent: "Based on some quick internet research, your parasitoid wasp is the Chalcid (Pteromalidae) Pteromalus puparum. They are widely used as a biocontrol for Pierids and are known to go for Vanessids (like Peacocks and Admirals) as well. They only lay in newly formed soft chrysalises."
