  <\/p>\n

L’\u00c9peire des bois (Aculepeira ceropegia<\/em>) est une araign\u00e9e de la famille des Aran\u00e9id\u00e9s, \u00e9galement appel\u00e9e \u00c9peire feuille de ch\u00eane en raison de l\u2019ornementation de son abdomen.<\/p>\n

L’esp\u00e8ce est pr\u00e9sente sur les plantes basses, dans les buissons, les prairies, les jardins ou en bordure des chemins.<\/p>\n

Elle affectionne les sites ensoleill\u00e9s et venteux.<\/p>\n

  <\/p>\n

L’\u00c9peire des bois est caract\u00e9ris\u00e9e par un abdomen \u00e9troit \u00e0 ses deux extr\u00e9mit\u00e9s, portant un motif dont la couleur varie du blanc au beige et dont la forme rappelle celle d’une feuille de ch\u00eane.<\/p>\n

La femelle mesure une quinzaine de millim\u00e8tres de long, le m\u00e2le environ 8 mm.<\/p>\n

  <\/p>\n

L’\u00c9peire des bois tisse une toile circulaire, qualifi\u00e9e d’orbiculaire, dans les buissons. Son centre est compos\u00e9 d’un treillis de fils.
\nLa toile comporte une spirale form\u00e9e d’un fil de soie gluante.<\/p>\n

L’araign\u00e9e se tient g\u00e9n\u00e9ralement sur une plate-forme de soie, en attente de proies.
\nLorsqu’un Insecte entre au contact de la toile collante, il provoque des vibrations en se d\u00e9battant.
\nL’\u00c9peire ainsi alert\u00e9e surgit et emmaillote rapidement la proie de soie, l’immobilisant.<\/p>\n

\u00c0 l’aide de ses ch\u00e9lic\u00e8res munis de dents (appendices associ\u00e9s \u00e0 la bouche, form\u00e9s d’une base large portant un crochet), elle hache les tissus de la proie tout en lui injectant un liquide digestif.
\nPour finir, elle aspire la bouillie issue de cette digestion.<\/p>\n
