La Belle Dame (Vanessa cardui<\/em>) est un Papillon de la famille des Nymphalid\u00e9s.<\/p>\n

L’adulte<\/a> est pr\u00e9sent de mars \u00e0 octobre dans nos r\u00e9gions. Il fr\u00e9quente les sites d\u00e9couverts et fleuris, secs et ensoleill\u00e9s, appr\u00e9ciant les fleurs des jardins et les chardons, d’o\u00f9 le nom commun de Vanesse des chardons qui lui est parfois attribu\u00e9.<\/p>\n

  <\/p>\n

La Belle Dame est ais\u00e9ment identifi\u00e9e \u00e0 ses ailes ant\u00e9rieures dont la face sup\u00e9rieure est de couleur orange ros\u00e9, parsem\u00e9es de taches sombres, grises \u00e0 brunes. \u00c0 l’avant, leur bordure est noire, tach\u00e9e de blanc.
\nSes ailes post\u00e9rieures sont \u00e9galement oranges, et portent de petits disques noirs.<\/p>\n

  <\/p>\n

Migratrice passant l’hiver au nord de l’Afrique, la Belle Dame arrive en Europe au d\u00e9but du printemps.
\nElle se reproduit au sud du continent d\u00e8s fin mars.
\nLes adultes issus de cette reproduction migrent vers le centre et le nord de l’Europe et s’y reproduisent aux mois de mai et juin. Dans ces r\u00e9gions, une ou deux g\u00e9n\u00e9rations se succ\u00e8dent, les adultes entreprenant une migration retour vers le sud \u00e0 l’automne.<\/p>\n

La dur\u00e9e du cycle de vie est de 5 \u00e0 8 semaines.<\/p>\n

Le d\u00e9veloppement embryonnaire<\/a> dure entre 3 et 8 jours, selon les conditions climatiques.<\/p>\n

Il donne naissance \u00e0 une chenille<\/a> qui construit un abri de fils de soie autour des feuilles dont elle se nourrit. Sa taille augmente \u00e0 la faveur de quatre mues<\/a> successives.<\/p>\n

Le d\u00e9veloppement post-embryonnaire<\/a> se poursuit avec la chrysalide<\/a>, qui est envelopp\u00e9e d’un abri de soie confectionn\u00e9 par la larve de dernier stade.
\nElle est le si\u00e8ge de la m\u00e9tamorphose<\/a> qui permet la formation de l’adulte.<\/p>\n
