French wildlife and beekeeping

Up to 25mm in length this huge leafcutter bee is a relatively new arrival in France that is rapidly and literally making itself at home and is nicknamed the Squatter bee for reasons that will become apparent.  First observations of this bee in France were made in 2008 in Allauch, north of Marseille. Since this date they have spread a long way and in the space of a few years have conquered a territory that includes all the southern half of the country!  The main concentrations not surprisingly follow the Rhone valley as far as Macon in the north to the Mediterranean in the south spreading West as far as Spain and East into Italy , Switzerland and Germany becoming relatively commonplace in gardens south of Lyon .

Originally t...

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 ...

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...
