This note relates the discovery of the Heart-shaped Tongue Orchid which was thought to have disappeared from Vendée in France as it had not been observed for decades.
In 1911, an excursion of the French Botanical Society made it possible to list all the notable plants of the damp hill of Les Hautes Termelières in the North of La Roche-sur-Yon (in Vendée, France). Nearly a century later, this note states the main plants that are to be found on the hill and more particularly 11 species of ferns.
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.
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.
Observation d’une genette, Genetta genetta (Linné, 1758), sur les rives du lac du Jaunay en Vendée
(2001)
The diurnal observation of a Genet, such as the one made in the bocage of Vendée (France) related here, is exceptional because this small carnivore is said to be so shy and so exclusively nocturnal.
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 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.
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.
L’Ophrys petite araignée, Ophrys araneola Reichenbach 1831, redécouverte de l’espèce en Vendée
(2001)
The Ophrys araneola which had not been seen in Vendée (France) since 1993 was rediscovered in may 1993 among a colony of Ophrys sphegodes. The writer underlines the risks of eventually confusing the two species and mentions the different characteristics of each in order to avoid any confusion.
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.
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).
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.
