a dangerous train ...
The pine processionary (Thaumetopoea pityocampa) is a moth of the subfamily Thaumetopoeinae in the family Notodontidae, known for the irritating hairs of its caterpillars, their processions, and the economic damage they cause in coniferous forests.
Toxicity :
Stinging hairs contain a toxic protein that is very irritating and inflammatory: thaumetopoein. It penetrates where the “harpoon” is planted: most often in the skin, but also in the eye, the nose, the mouth…
The hair breaks and the toxin released causes a reaction similar to that of nettle stings: red pimples in the form of blisters, red itchy patches, appear on the skin.
General symptoms may occur in the event of significant exposure. The immune system then goes into overdrive, which can lead to a sudden drop in blood pressure, discomfort or loss of consciousness.
Is there a risk for animals? With their noses at ground level, animals are exposed to contact with these stinging hairs, particularly dogs. They can get it on their coat, or even take a caterpillar in their mouth, which can cause very serious inflammatory reactions including necrosis of the tongue.
Un train dangereux ...
La processionnaire du pin (Thaumetopoea pityocampa) est un papillon de nuit de la sous-famille des Thaumetopoeinae de la famille des Notodontidae, connue pour les poils irritants de ses chenilles, leurs cortèges et les dégâts économiques qu'elles provoquent dans les forêts de conifères.
Toxicité
Les poils urticants contiennent une protéine toxique très irritante et inflammatoire : la thaumétopoéine. Elle pénètre là où le « harpon » s’est planté : le plus souvent dans la peau , mais aussi dans l’œil, le nez, la bouche…
Le poil se casse et la toxine libérée provoque une réaction semblable à celle des piqûres d’ortie : des boutons rouges sous forme de cloques, des plaques rouges qui grattent, apparaissent sur la peau.
Des symptômes généraux peuvent survenir en cas d’exposition importante. Le système immunitaire s’emballe alors, pouvant mener à une baisse brutale de la tension artérielle, un malaise ou une perte de connaissance.
Y a-t-il un risque pour les animaux ? La truffe au ras du sol, les animaux sont exposés au contact avec ces poils urticants, notamment les chiens. Ils peuvent en avoir sur le pelage, voire prendre une chenille dans leur gueule, ce qui peut provoquer des réactions inflammatoires très graves jusqu’à une nécrose de la langue.

Ardnamurchan never disappoints...
I'm just back from a two week trip to the peninsula on the west coast of Scotland. Lots of walking, exploring, a little bit of wild swimming and plenty of time with my favourites; the Pine Marten.
The jumping shot is an image I've had in my mind's eye for some time. I tried it last year and had some luck, but knew I could do better. I'm really chuffed with this image plus quite a few others over a few evenings trying it!

"pine cones
They're little treasures that drop from the trees and wait like new friends to be found.
Pine cones show us that we are all different, all beautiful, all perfect in our imperfection. "

These beautiful birds have started showing up in the back yard over the last few weeks. I had never seen one before, and I believe them to be a rare find in northern New England.
taken with a humble Minolta 200mm legacy lens, and shot through the glass of the deck door.
thank you for visiting, and for your kind comments and favorites. they are greatly appreciated!

Steilküste Praia da Falesia
Mit seinen bunten Klippen und dem goldenen Sand ist der Praia da Falesia an der Algarve einer der schönsten und beeindruckendste Strände Portugals.
Die Formen und Farben an dem 6 km langen Sandstrand sind unglaublich. Die leuchtend grünen Pinien auf den Klippen sind ein optisches Highlight .
Pines of any sort are a rarity around here, spruce being the dominant tree by far.
This is a 'transplanted' lodgepole pine from down near Whitehorse YT, covered with hoarfrost.
