New Bat species for France - Myotis crypticus


Le Murin cryptique  Myotis crypticus   Feb 2019

A new species of bat has been discovered in wooded areas of Italy, France, Switzerland and Spain.

This brings the number of species to be found in France
To 35

It is very close to Natterer's bat (Myotis nattereri) and positive identification has so far relied on DNA analysis. Despite their closeness they do not hybridise. 

Reproduction colonies are usually in hollow trees but can be in artificial man made structures. Hibernation takes place underground in fissures. Much remains to be known about this species.

Beetles in the Firewood in France



Every year in France, usually from about February, some people find their houses invaded by small red or reddish-brown beetles. This is by no means everywhere and many people will never see one, however where they are present they can sometimes be observed in relatively large numbers.



The creature concerned is a Longhorn Beetle, Pyrrhidium sanguineum, although being only 8 to 12 mm it is rarely recognised as being one. Known in English as Welsh Oak Longhorn Beetle and its common French name is La Callidie Sanguine).

Females lay eggs in crevices in dead or freshly cut wood with bark that is exposed to the sun from March – June and are polyphagous in nature using a range of deciduous trees, but with a preference for oak (Quercus spp.).  Larvae burrow into the timber making galleries up to 60cm in length where, when fully grown, they pupate.  They can’t use seasoned timber and usually have an annual life cycle, occasionally this can be two years.

When this wood is stored or kept for a while in the home or perhaps a garage as firewood the adult beetles tend to emerge earlier due to the higher ambient temperature. Where firewood is stored outside in proximity to the home they may be seen a little later in the year when it is warmer.

Fortunately for us we don’t need to worry as they are completely harmless in our homes and can be popped outside where they belong.

Glanville Fritillary France


The Glanville Fritillary, Melitaea cinxia,  is named after Lady Eleanor Glanville, a 17th century Lepidopterist who discovered this species in Lincolnshire. She first discovered this species in 1702 when it was first named as the Lincolnshire Fritillary and only later in 1748 was it was officially re-named the Glanville Fritillary.  These days it is mainly confined to the south coast of the Isle of Wight, with the occasional colony, typically short-lived, appearing on the South Hampshire coast.

It is a butterfly that can be found in most regions of France and the Channel Islands where it forms small colonies where there is suitable habitat. There has been a reduction in numbers especially in the north and west of its range with habitat loss being the most likely main cause.

They require low growing sparse grassland, natural flower meadows, scrub, woodland edges and even roadside verges but due to the increase in what is called improved pasture and in cereal production in the broad sense there is increasing isolation of populations. The widespread use of Roundup (Glyphosate) to keep the ground clear in vineyards is another threat to this butterfly along with a number of other species.  

In the southern half of the country there are usually two broods with the first on the wing in April / May and the second generation June / September. Regardless of whether there is a single brood or two broods in a season they over winter as caterpillars in webs that they form on the ground with their food plant which is principally Plantain hence the French common name of La Mélitée du Plantain. 


Lady Eleanor’s collection of butterflies still exists and is housed in the Natural history Museum.

Field beans as a fodder crop for sheep in France

In the autumn of 2018 several large fields where we live were planted predominantly with Field beans with a few other plants including fodder radish, mustard and phacelia. This has never happened here before and I was quite excited at the thought that these may be left to flower in the spring which would have been great for all manner of species including my bees. However it seems this is not going to happen.

Yesterday when I was out with my dog I saw that one of the fields was electric fenced and had sheep in it and that the adjacent field was also electric fenced but had been grazed.  



From both an agricultural and environmental perspective I can see the benefits in this. The crop as a green manure provides good winter cover, prevents nutrient leaching, adds nitrogen and other nutrients to the soil and the owner of the sheep has fresh early season fodder for their animals.

I should explain that sheep aren’t pastured where we live as it is more profitable to grow cereal crops and that the farmer that owns these particular sheep also grows cereals here including barley for his winter sheep feed. His sheep are kept for the summer some distance away on land that is unsuitable for cereals and are transported to his farm here for winter where they are housed in a huge barn where they are lambed before being returned in spring to their summer grazing pastures.

Regardless of your views on eating meat this would appear to be an improvement for the animals involved and the land.

Hunt or hunting days in France


There are always people asking what days are the hunting days in France and the simple answer is that there is no National law that prohibits hunting on any day of the week during the open hunting season although various Associations keep petitioning for Sundays to be hunt free.


Part of the confusion where it exists is that there isn’t simply one type of hunting or la chasse and that la chasse is often erroneously thought of as being uniquely chasse en battue that involves a minimum number of participants with some driving or flushing through an area using dogs pushing any animals, (boar, deer, fox), out into the open to where one or more hunters wait with guns. Usually this type of organised hunt takes place on two or three specific days of the week that are agreed at the commune level, (ours is Thursdays, Saturdays and Sundays) and the people that participate in this like to call themselves La Chasse.  However rough shooting for smaller creatures, birds, rabbits, hares etc. can take place on any day of the week although in practice Wednesday afternoon is usually avoided due to being a half school day.

To be clear - La Chasse can be defined as using various means in order to capture and kill creatures either for eating or for destruction and no single group of hunters can claim this as belonging to them alone.

There was a brief period from July 2000 and July 2003 when hunting was banned on Wednesdays and this was instituted throughout France at the request of the Minister of the Environment, Dominique Voynet, through Article 24 of the hunting law 2000-698 of 26 July 2000, which stipulated: "Article L.224-2 of the Rural Code is worded as follows: ... The practice of shooting hunting is prohibited from Wednesday 6 am to Thursday 6 am".  However in 2003, the repeal of this "no-hunt Wednesday" was included in the bill on hunting put forward by Roselyne Bachelot then Minister of Ecology! It was then voted into law by the majority UMP-UC

The law of 2003-698 of July 30, 2003, by Article 27, thus cancelled this provision altogether (which had in the meantime been transposed to the rural code to that of the environment): "The last paragraph of the Article L. 424-2 of the Environmental Code is deleted."

Therefore only the Prefect of each Departement can order days without hunting in application of the article R.424-1 of the code of the environment but in practice this rarely occurs.

Other limits that are set each year at the Departemental level each year limiting or restricting the time periods and numbers of specific species will apply.

Beaver in Pyrénées-atlantiques, France

In the Pyrénées-Atlantiques the first photos emerge of a beaver after several centuries of absence for this species in this area of France.

In February 2018, a naturalist on vacation in the Basque region of France discovered indices of beaver presence on the banks of the Nive at Ustaritz (64) in the form of cut tree trunks and debarked branches.

This led to the realization of a joint research by the ONCFS,
Thomas Ruys of Cistude Nature association, a representative of APPMA, (the angling federation), and a local naturalist.

This investigation confirmed that the indices were indeed those of a beaver but didn’t provide any actual sightings of one.
Following these observations of new cutting activity on fresh trees in November 2018, a photographic trap was installed which resulted in pictures of a beaver working on the trunk of a tree!
For the moment only one animal has been identified that is suspected of being an individual dispersed from the Spanish population of beavers present on the basin of the Ebro or perhaps as seems more likely one or more have been introduced clandestinely.


The ONCFS beaver network will continue in the coming months monitoring the sector, as well as upstream and downstream areas, to check whether it is a permanent installation and to try to better understand the dynamics of the species.

The question is has the beaver made a comeback in the Pyrénées-Atlantiques after several centuries of absence or is this a lone example with unknown origins?
