[Observations related to a strange habitat of Atheta (Mocyta) clientula (Erichson, 1839) and of some other uncommon species (Coleoptera Staphylinidae)]
1996
Bruge, H.
The author has established that, several years in succession, the Staphylinid beetle Atheta (Mocyta) clientula (ER) was present in number, from a few tens to about 1000 specimens, in the thick layer of damp, dead leaves from Salix fragilis, that accumulate in the cornice of a little farm, at Ellezelles (Province Hainaut, Belgium). Some others, uncommon Staphilinids were present too in the same layer: Atheta (Anopleta puberula (SHARP), Atheta (Mocyta) orbata (ER.) and Phyllodrepa (Dropephylla) ioptera (STEPH.). A few hundreds specimens of this last species were also dicovered in cushions of mosses, on a 20 square meter roof of asbesth-cement ripple plates. Hypothesis are presented regarding the reasons of the presence in such a number of these rather uncommon species in these particular environments.
