The Orchis simia is a rare orchid in Vendée (France). Historical data and the amount of books published about it are mentioned here. A new find on the limestone formation of Chantonnay has been added to the present distribution of species.
After 1985, the otter (Lutra lutra) was not found any more on the Sèvre Nantaise (France). From 1997, a careful exploration revealed presence signs of its presence showing the coming back of this mammal.
The Genet is a little carnivore whose status is not very well-known in Vendée (France). The methods for a county survey about these carnivores are set out in order to get information about its presence. The results will make it possible to map out an atlas showing where it is located and where it lives.
The Revue des Sciences naturelles de l’Ouest was edited in the years 1891-97. Although poorly known, it contains valuable papers on the natural sciences in Western France, particularly in Vendée. After a short presentation, we give here the content tables of this periodical together with a list of public libraries where it can be found.
This article summarizes the observations of Odonatas gathered over the last fifteen years in Vendée. It results from collective research work by more than forty naturalists. A map locating each of the 58 species of Odonatas is given as well.
The writer mentions the existence of the Ophrys passionis in Loire-Atlantique and in Vendée (France), which are two countries where this Orchid had never be seen before. All the observations so far emphasize the hypothesis that this Orchid is different from the other related Orchids through its ability to adapt to a specific pollinator, Andrena carbonaria.
A first inventory of Yeu island’s Orthoptera (Vendée, France) allow us to list 23 species and 4 species of the allied orders Mantodea, Phasmodea and Dermaptera. A faunistic study was established on each species and a discussion gives an evaluation of the imprint of human activity on insular Orthoptera’s communities.
This is a preliminary inventory of Coleoptera, Lucanoidea, Scarabaeoidea found up to now in Vendée (France). The supposed status of each of these species (frequency and distribution …) is mentioned within the scope of our present knowledge.
The writer describes the discovery of Depressed Groundhopper, Tetrix depressa (Brisout, 1848) in a disused quarry in Benet. It's a new species of Groundhopper in Vendée (France).
Tracks and faeces of otter are abundant around the lac du Jaunay (Vendée) but this animal is very fierce and nocturnal. Nevertheless, an otter was observed in very good condition at midday, in June. It was fishing in a small pound near the lake. This note describes the behaviour of this otter.
