Pine processionary moth and hairy caterpillars in France

Image
With the aid principally of social media in all its aspects the Pine processionary moth increasingly strikes fear into the population with all the stories about how dangerous they can be. There is certainly no denying their harmful nature should someone or their pet animal come into close physical contact with them or breathe in their harmful hairs but we mustn’t let this lead us into a panic that results in the destruction of our other native hairy or web forming caterpillars that need all the protection that they can get. The first thing to understand is that Pine processionary moth nests are always in Pine trees and only rarely in Fir trees. A caterpillar web anywhere else is a different type of caterpillar. Secondly, when on the ground they will invariably be found in the classic processions “nose to tail” and only very rarely as individuals should they have been blown from the trees by storms. Thirdly, they will only be found on the ground when Pine or Fir trees ...

A Grass carrying wasp and a Mud dauber in France

Image
A couple of interesting introduced species in France that many people will have come across and which are noticeable due to their somewhat unusual behaviour. Isodontia mexicana known as the grass carrying wasp and Sceliphron curvatum a “Mud dauber” have established themselves rather successfully in France. Isodontia mexicana can be found in all regions and Sceliphron curvatum is so far restricted to more or less the southern two-thirds of the country but the expansion is rapid.  Both belong to the Sphecidae which are a cosmopolitan family of wasps of the suborder Apocrita that includes sand wasps, mud daubers, and other thread-waisted wasps. Isodontia mexicana arrived in Europe from North America in the 1960s. For several years, it remained confined to the Mediterranean region, but from 2003, a year which was particularly hot, it began to extend its range northward. It is currently found in France , Switzerland , Hungary , Italy and Spain . They are black with smoky ...

Pine processionary moth and Napoleon 3rd of France

Image
So now it's warmed up a bit following that rather nasty period of cold weather there are the inevitable sightings of Pine processionary m oth, Thaumetopoea pityocampa, caterpillars and all the usual corresponding scare comments that we, our children, our dogs, cats and horses will all die if they so much as get near them and that the vets and hospitals all over France will be unable to cope. Let's face it there is nothing like a bit of shock and horror to lighten up our dull winter days. Of course this is not to say that the caterpillars can't be a problem and that due diligence is required when walking anywhere near Pine trees, equally that logic would normally dictate that if you have a Pine tree in your garden and knowing this potential danger it may make sense to remove it - there are very few parts of France where they belong naturally. 200 years ago in most places you would have been hard pushed to find one in most areas and it is another example of how c...

Large creamy white grubs in French gardens - Stag beetle, Rose Chafer & Cock Chafer

Image
People are always asking on Facebook and elsewhere what the large creamy white grubs or larvae are that they find in their gardens and hopefully this page goes some way to answering that without all the complications of seeing how they crawl.  Go to the link: Stag beetle, Rose Chafer & Cock Chafer Chris

Goat Moth - a spectacular caterpillar

Image
Caterpillars can be some of the most spectacular and pretty creatures that we can encounter here in France and the caterpillar of the Goat moth, ( Cossus cossus ), is a classic example and it's the caterpillar that gives this moth its name as it emits a strong and rather unpleasant smell  reminiscent of a male goat although having handled a few I’ve never been aware of it myself.  The moth has a wingspan of 9cm or so, have light grey wings which are covered in black speckles.  Sadly I have never seen one and it may well be that there aren’t many where I live, (my wife did see a caterpillar about 10 years ago on a nearby track but nothing since), however this isn’t so unusual as apparently they aren’t regularly observed and the moth doesn’t feed. By all accounts they aren’t a common species and as we will see the larvae are regularly destroyed which may account for their decline. Twice a year in May and October Hope Association holds a three day fund raising even...

In our fields recently.

Image
It’s fair to say that our fields aren't the most exciting habitat in the region although they probably are the most species rich as a whole for the immediate area albeit most of the species are common, but then common doesn't mean there aren't increasingly reduced numbers at a local level – it all adds up and ours is probably the only decent size bit of proper grassland for many kilometres, everything else is cultivated or so called improved pasture which is really only one step up from a wheat field in terms of species usefulness. Anyway this isn't about the surrounding area but just a small selection from some idle wandering here and there in our own fields recently with the camera just taking photos of anything that caught my eye and hopefully draw a little attention to the simple plants that can make all the difference. Starting with a couple of plants that once introduced to grassland will soon establish and sort themselves out, Crown Vetch and Birds Foot ...

What's hiding under the hive roof

Image
I think it's best to start for non Bee keepers with a short explanation of a basic hive structure. Shown below is a French Dadant Ruchette which is basically a small starter hive and is exactly the same as a full size Dadant hive in design, Dadant being a style of hive. The box structure at the bottom is called the Brood box which is where the bee colony lives.  Next with the hole in the middle is the Crown board or the cover that goes over the bees. The hole in the  center  is for placing a syrup feeder over or for placing a block of fondant for the bees to eat. When not in use it is normal to close it with a small cover. Finally standing on edge in this photo is the outer metal covered weatherproof lid. All very simple really. From time to time I lift the outer lids on my active hives to check everything is OK and as it's quite common to find various creatures that have made it their home I thought I'd take a few photos over the last week to ...
