  <\/p>\n

La Grande Tortue (Nymphalis polychloros<\/em>), \u00e9galement appel\u00e9e Vanesse de l’orme, est un Insecte de l’ordre des L\u00e9pidopt\u00e8res<\/a>.<\/p>\n

Elle est pr\u00e9sente dans les bois de feuillus o\u00f9 all\u00e9es et clairi\u00e8res sont ensoleill\u00e9es ainsi que dans les bois clairs.<\/p>\n

Elle visite assez rarement les fleurs, se nourrissant plus volontiers de la s\u00e8ve s’\u00e9coulant des arbres.<\/p>\n

  <\/p>\n

D’une envergure de 50 \u00e0 55 mm, la Grande Tortue poss\u00e8de des ailes dont la face sup\u00e9rieure, de couleur orange rouille, est parsem\u00e9e de taches sombres. Le bord externe des ailes post\u00e9rieures est \u00e9galement sombre, mais bord\u00e9 de lunules bleues.
\nLa face inf\u00e9rieure des ailes est marbr\u00e9e, \u00e0 dominante brune, ce qui assure le camouflage de l’animal lorsque ses ailes sont ferm\u00e9es, au repos.<\/p>\n

  <\/p>\n

La Grande Tortue hiverne \u00e0 l’\u00e9tat adulte<\/a>, dans des endroits frais et sombres comme des troncs creux ou des foss\u00e9s. Elle en \u00e9merge en mars-avril \u00e0 la faveur des premiers beaux jours.<\/p>\n

La reproduction intervient au printemps, avec une ponte en avril. Les \u0153ufs forment le plus souvent une nappe continue autour d’une tige dans une partie \u00e9lev\u00e9e des plantes h\u00f4tes.<\/p>\n

Au terme du d\u00e9veloppement embryonnaire<\/a>, les \u0153ufs lib\u00e8rent des chenilles<\/a>. Elles demeurent group\u00e9es dans une toile de soie au d\u00e9but de leur \u00e9volution, puis deviennent solitaires.<\/p>\n

Apr\u00e8s 5 semaines environ de d\u00e9veloppement post-embryonnaire<\/a>, elles se transforment en chrysalides<\/a> d’o\u00f9 la nouvelle g\u00e9n\u00e9ration \u00e9merge \u00e0 partir de juin.<\/p>\n

Une seule g\u00e9n\u00e9ration annuelle est observ\u00e9e.<\/p>\n
