Clubiona
Clubiona is a kind of spiders spread in the whole world, except in South America where one finds any only in Chile. It counts 429 species.
In Europe, one counts 55 of them whose identification is difficult on the ground because of the lack of manifest distinctive signs and their night life.
The Clubiona live one year, are adult in spring and the beginning of the summer.
A great part lives in the wetlands and the low vegetation. They build silk retirements in general.
The coupling lasts one hour: the male uses its chélicères, long and frayed, to maintain the female.
The species living in the trees deposit simply their pale cocoon of eggs yellow in a papered silk sheet. On the other hand, the females of the species living more close to the ground bend a sheet of graminaceous in a characteristic way (in the shape of tetrahedron) and remain to be supervised until the blossoming of eggs.
