Violet drop wing - Trithemis annulata

Image
  Violet drop wing Trithemis annulata Thrithémis annelé or Thrithémis pourpré Location - Peyras, 16270 Roumazières-Loubert, France Recently, I was out relaxing, just having a good time really on a Sunday at one of those man-made recreational lakes that France excels in, but with my eyes always on the lookout, I saw quite a large number of bright purple dragonflies that I had never seen before. Aerial view of lake I only had my phone with me, and I struggled in the bright sunlight to focus and get a half-decent photo, which, as it turns out, isn't that bad. What I didn't realise at the time was that these violet dragonflies were all males and that the females are a rather drab brown. Male Violet drop wing Originating in Africa, it first appeared in Spain in 1978, Corsica in 1989, and then mainland France in 1994, where it is now well established and rapidly expanding both to the north and to the east along the Mediterranean coastal band and the Rhône valley....

Asian Hornets in France- A balanced and scientific approach is essential.

Image
  Source info - Office for Insects and Their Environment, France Asian hornets are now well established in mainland France, and we have to accept it: it will be impossible to eradicate this species. Given this reality, the question is not how to make them disappear, but how to learn to limit their impacts without worsening an already alarming situation for French wildlife. Adopting a balanced approach, based on scientific knowledge, is essential today. Protecting domestic bees is important socially and economically, but this should not come at the expense of other wild insects that help maintain functional ecosystems. Managing Asian hornets cannot rely on isolated actions or responses driven by fear or instinctive rejection. On the contrary, it requires cooperation between beekeepers, scientists, local authorities, and public officials in order to put forward coherent, well-thought-out, effective solutions that respect living beings, especially other animals. It's important that de...

Dangerous Asian Hornets in France

Image
  We are increasingly reading about hospitalisations and deaths resulting from Asian hornet stings BUT are Asian Hornets any more aggressive or dangerous than our native European Hornet and Social colony forming wasps? You may think so if you only go by media sources but in reality this isn't actually the case despite there being some well publicised reports of deaths. Read the full post.

Sexton or Burying beetles in France

Image
  Our house is full of places where animals live and overall we are happy with that and it rarely causes any actual harm although occasionally something dies which needless to say can smell a bit. Fortunately, as always, the natural world is well equipped to deal with any small corpses that are inaccessible, (as they invariably are), and Burying or Carrion beetles are one of the insects that make their living from such things. There are some 20 odd species in France with a total of 30 species in Europe although not all are true burying beetles; some of them eat fungi or rotting vegetation.     This year in September we were finding Nicrophorus vespillo in one part of our house and I would speculate that they had been on a dead Loir , (Edible Dormouse), probably behind the bath or false wall in the downstairs bathroom, one of the places where they frequently live. These amazing beetles can smell a corpse from a vast distance using the highly sensitive hairs on the e...

Bees killing hornets in France

Image
I know it is stating the obvious but every year is different in the natural world and no two years can be the same, however this is becoming increasingly exaggerated. Habitat loss, agricultural methods and climate change along with other factors are causing rapid major changes for our native species requiring them to adapt or perhaps in some cases disappear completely. For some species this is creating opportunities and they have expanding populations that are sometimes associated with an expansion in their range. However for most species there are accelerating declines and this in turn leads to changes of behaviour as species attempt to adapt. Where I live most insect species have been in overall decline for the last 25 years and this year has been abysmal for them but I want to talk specifically about hornets.  Following the usual slow start as nests were established and populations grew I started to see a gradual increase in both Asian and European hornets in t...

Chafers and Honeybees in France

Image
The other day a chap on a French Beekeeping Face book group posted a photo of a beetle trying to get into one of his hives.    His initial reaction having “Googled” was that it may have been a Large hive beetle, Oplostomus fuligineus , a species that is found in Africa  and although this has not yet been recorded in France  we can’t be sure where anything is going to turn up these days. New non native species seem to arrive on almost a weekly basis in France and the Small hive beetle, Aethina tumida , another non native, has been found in Italy but as of this moment hasn’t reached France . Anyway it was clearly a Chafer, that much was indisputable but not a Large hive beetle. I was sure, (ha,ha,ha), at first that it was dark Rose Chafer beetle due to its general appearance and size, (close to 2cm). However I couldn’t find any evidence of Rose Chafers trying to enter hives and although they are plentiful at our place, (Rose chafers and hives), I have never see...

May bug – Cockchafers - Hanneton commune and Hanneton forestier in France.

Hardly extraordinary I can hear people thinking but the other day I saw a May bug here, first one in several years. In fact in the 25 years we have been here there have only been a couple of years when I have seen them.    A May bug or Cockchafer generally refers to Melolontha melolontha or the Common Cockchafer but there is an almost identical species in France with which they could be confused which is the Forest cockchafer, Melolontha hippocastani, which is a species found in woodlands.   Generally Melolontha melolontha is considered an to be   an agricultural pest and they were brought almost to the point of extinction in the arable areas of France following the use of chemical insecticides such as DDT and Lindane. Both of these caused massive environmental harm before being banned from use. In the 19 th century prior to insecticides being available the beetles were collected by hand to be killed, a process called “hannetonnages” that had some effe...

France and the banning of neonicotinoid insecticides

Image
France Becomes The First Country To Ban All Five Pesticides Linked To Bee Deaths. Most of us will have seen this or similarly worded headlines on a myriad of mainstream media sites, blogs, alternative information sites, and sites that are simply clickbait for advertising revenue. Many of these so-called articles are full of sensational, erroneous statements and speculations that have no factual or scientific foundation whatsoever. Large numbers of people will have liked, shared, and commented on these pages without any idea of what the reality is or giving it any real thought.   Most of us do this at some time or another on social media because to do otherwise would be too time-consuming. So what actually is the reality? Yes, France has banned the use of five types of neonicotinoid insecticides that by definition have been shown to cause harm to insects.   This is two more than the EU has banned, although countries frequently derogate from the ban in certai...

Assassin bug the Masked hunter, Reduvius personatus, in France

Image
Masked hunter, Reduvius personatus ,  Réduve masque Found in most regions of France this member of the True bug family is known as an Assassin bug and due to its secretive nocturnal behaviour it tends to go unnoticed even when in your home. They are especially fond of old houses, barns and outbuildings where they hunt other insects including bedbugs, silverfish, book lice and flies. However they will eat any number of small insects and can also be found in other habitats including woodland, scrub and grasslands but always avoiding the light. Where ever they are they are never in large numbers. Although they bite and kill their prey by piercing them with their robust rostrum they rarely use this against humans unless handled roughly but if they do it isn't dangerous but can be extremely painful. They spend the winter as juveniles and then breed in May or June having reached the adult stage.   During their development stages, (instars), they exude a st...

Ladybirds in France including the Asian Harlequin Ladybird

Image
Every year in autumn and spring there are articles in the media, especially in the UK, about the Asian Ladybird, Harmonia axyridis , or Harlequin Ladybird as it is known, one of several thousand different non native species introduced in both France and the UK although only a few are ladybirds. This species is generally regarded as the most invasive ladybird on Earth and although they undoubtedly have an environmental impact due to their high breeding and survival rate combined with their voracious appetite most experts are of the opinion that they are now so abundant that there is little if any point in killing them. Harlequin ladybirds, above, are extremely variable but most have a clearly defined "M" or "W" on the pronotum. Although they feed most commonly on aphids they have a wide food range that includes scale insects, adelgids, the eggs and larvae of butterflies and moths, many other small insects including other ladybirds, pollen, nectar, an...

Hedgerows and Dry Stone Walls in France

Image
As soon as we start to take a look at either Hedgerows or Dry stone walls it soon becomes clear that in France as in many parts of the UK it’s difficult to talk about one without the other. Although there have been what could loosely be called hedgerows to some extent in France since before Roman times they really started to come into their own in the 16 th and 17 th centuries as the available land not already owned by the nobility or the Church was eagerly snapped up by the wealthy middle classes, the bourgeoisie urbaine. They used hedgerows to define their boundaries, to protect their crops and to prevent other farmers from grazing their land. Apparently hedge laying, (plessage), was widely used throughout France but has disappeared without a trace in many regions since the 1960’s and I have yet to see an example or a remnant in our region.  From the end of the 19 th century and into the first half of the 20 th century the industrialisation of agriculture started to c...

Hunting in France and the decline in species

Image
What role, if any, does hunting play in the massive species population declines we are experiencing across the board in France? Hunting is one of those subjects that invariably divides people into being either for or against with both sides of the argument frequently suffering from the blindness and anger that comes with entrenched attitudes but the question that needs to be asked is how much harm results from hunting relative to other perhaps more acceptable activities when it comes to the declines in wildlife that we are witnessing?  Looked at objectively it soon becomes clear that although the practice of hunting may be abhorrent to many people it doesn’t really have any impact on the populations of deer and boar, (gros gibier or large game as they are known), which is the main form of hunting in France . Many birds are specifically bred to be hunted such as Pheasant, Red-legged Partridge & Mallard and as such don’t really count, (see link at the bottom). Where...
