Distribution mondiale
toute l'Europe excepté au Nord, Bassin méditerranéen
Caractères distinctifs, espèces
Taille - femelle : 6-8 mm, mâle : 4-6 mm.
Agalenatea redii se distingue facilement par son abdomen pratiquement rond et son corps recouvert d'une longue pilosité. L'abdomen est pourvu dorsalement de dessins très variés avec des couleurs souvent brunes mais pouvant aussi présenter des taches orangés, jaunes, souvent d'aspect velouté. Il y a souvent deux taches blanches à l'avant de l'abdomen. C'est la seule espèce du genre Agalenatea.
Milieux colonisés
Elle colonise les plantes basses des prairies, friches, landes.
Chasse
La toile est tissée au printemps en prairies entre les tiges mortes qui restent de l'année précédente. Elle se situe donc à quelques dizaines de centimètres du sol. La retraite est souvent tissée sur le capitule d'une de ces tiges, c'est un tissage dense, plat. Le centre de la toile est parfois pourvu d'un lacis de soie opaque, faisant office de retraite. Les proies sont surtout des insectes volants.
Développement, cycle
Le cycle est annuel. Les mâles sont présents d'avril à juin, les femelles apparaissent en avril, sont abondantes jusqu'en juin-juillet et deviennent beaucoup plus rares à partir d'août.
La période de ponte a lieu au début de l'été. Le cocon est abandonné par la femelle sur la végétation. Les œufs, de 70 à 130, sont recouverts d'une épaisse soie verdâtre. Il semble n'y avoir qu'une seule ponte par femelle. Les jeunes éclosent rapidement et sont à l'état subadulte au début de l'hiver. Ils deviennent adultes au printemps suivant.

The map presents a summary at the 10 x 10 km grid of the observation data for the species transmitted to the SINP. These data have been subjected to validation filters.
The map presents a reference distribution layer of the species at the scale of departments and marine sectors. The presence and absence data were established by expertise within a network of partners. This reference distribution is used in the validation process of the SINP data at the INPN level.
Corresponds to a report on the basis of at least one observation proved within a period of 10 years (20 years for little-known invertebrates) preceding the year and no presumption of extinction since obtaining the last data nor doubt on reproductive and implemented nature of this population. For migratory species, the presence indicated concerns areas of reproduction.
This status is based on one or more of the following criteria:
This point covers the absence, more difficult by nature to demonstrate than presence. This status is based on one or more of the following criteria:
This status must be assigned to a department in which the presence of the species is casual.
Particular case of absence due to a proven extinction less than a half century ago (older disappearances are treated as "no probable or definite").
In the state of knowledge, we can not comment on the presence or absence in the current department. This is the default status when not comprised in one of the previous categories or whenever there is doubt.
The map shows the global distribution of the species based on GBIF data (Global Biodiversity Information Facility).
