Log hive at a French Chateau

Image
Chateau bees. It’s not unusual to get called out to bee swarms and colonies between the windows and shutters of French houses. After all, it's an ideal space if the shutters are closed.   The other day I was called to one in a Chateau, all very straightforward, with a nice-sized window for the Ruchette, (small hive box). Victoria, the woman from the Chateau, wondered if they had come from the bees in the large section of Lime tree trunk from the tree that they had cut down in the late autumn.   Immediately she had my attention, and so the story unfolded. It seems the tree had to be cut down as it had become dangerous, having split in a storm. They insisted that the section with the bees in it be cut out in one large piece, and this was later moved to a suitable location in the grounds, with the open ends covered up to provide protection but with enough gaps for the bees to come and go. Walking down to where it was, I was impressed by the size of it and although it wa...

Purple emperor and Lesser purple emperor butterflies in France

Image
Purple emperor and Lesser purple emperor butterflies – a simplified life cycle and how to see them. These two butterflies spend most of their time in the woodland canopy where they feed on aphid honeydew, or occasionally when they descend to feed on sap runs or, in the case of the male, animal droppings, carrion or moist ground that provide much needed salts and minerals which are generally the only times we get the chance to see them. Click on images to expand  Above - Male  Above - Female  Both species use willows, principally Goat willow, and in the case of the Lesser Purple Emperor poplars as well, especially Populus tremula , for their caterpillars to feed on. Eggs are placed singly on leaves near the tree canopy and the caterpillars have an extraordinary life cycle that can last 300 days or more with various pauses between each instar change, the last before pupation being a long hibernation through winter in a crevice or branch fork wrappe...

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...

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 ...

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. Chris

Beetles in the Firewood in France

Image
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 ...
