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?

Gendarmes are also Red and Black bugs, (Fire bugs), in France, not just Police personnel.

Fire bug Pyrrhocoris apterus le Pyrrhocore or Gendarme Many will know this highly successful common bug by the name of Gendarme or perhaps, depending on the region, names such as Suisse, Soldat, Punaise rouge, Cherche-midi or Punaise au corps de feu , all of which are widely used French vernacular names for this colourful insect. As most people will have noticed the "gendarmes" are gregarious and as such live in colonies, which can be described as "gendarmeries", and can number several hundred or even thousands of individuals. Their Black and Red colouration apparently contains a substance that gives them some immunity from predation and as such they make no attempt to hide and even have a very pronounced propensity for collective sunbathing, hence the name of " Cherche-midi " . Even in winter on a warm day a sunny stone wall or tree trunk will see them out and about. Click on photos to enlarge Being well equipped defensively ...

Deaths head hawkmoth and Great Peacock moth.

OK, size isn’t everything but the two largest moths we find in France are quite spectacular in both adult form and caterpillar and as such I think are worth a mention, they rarely fail to rise a "wow" when someone finds one. The Great Peacock Moth Saturnia pyri is the larger of the two and is Euorope largest moth with a wingspan of between 100 and 150mm, (4 to 6 inches), although some texts suggest that 200mm, (8inches), is possible.

House Centipede - la Scutigére, (Scutigera coleoptrata) in France

Older French stone built houses invariably play host to a number of species and that includes these fascinating little guests although not all people are thrilled by their presence or their speed when they get a move on reaching speeds of up to 0.4 meters per second. Although in everyday usage they are called a centipede or “hundred feet” they actually only have 15 pairs of legs when fully grown giving them 30 legs. The last 2 legs are particularly long, longer in fact than their antennae reaching twice the length of the body and can be nearly 6 cm. They use these long legs to form a kind of lasso which is one of the methods they use to capture prey. Note that the common terms centipede and millipede are never meant to be factual and both are grouped together as myriapods or very many-footed. Eggs are laid in spring and the larvae when they hatch look like miniature versions of the adult but with only 4 pairs of legs. They gain a new pair with the first moult and t...
