Hesp\u00e9rie de l’alc\u00e9e (Lyon, juillet 2012 – G. Rigaud)<\/figcaption><\/figure>\n

  <\/p>\n

L’Hesp\u00e9rie de l’alc\u00e9e, \u00e9galement appel\u00e9e Grisette (Carcharodus alceae<\/em>), est un Papillon de la famille des Hesp\u00e9riid\u00e9s.<\/p>\n

Les adultes<\/a> sont pr\u00e9sents d’avril \u00e0 octobre, fr\u00e9quentant les espaces d\u00e9couverts fleuris et ensoleill\u00e9s (coteaux, clairi\u00e8res, prairies, pelouses, parcs et jardins) mais aussi les terrains rocheux secs.<\/p>\n

  <\/p>\n

L’Hesp\u00e9rie de l’alc\u00e9e est identifi\u00e9e notamment \u00e0 l’aspect de ses ailes.<\/p>\n

Leur face sup\u00e9rieure est un m\u00e9lange de motifs de couleurs brun clair, brun fonc\u00e9 et gris. Elle est orn\u00e9e de quelques taches blanches sur les bords.<\/p>\n

Leur face inf\u00e9rieure est pour sa part plus uniform\u00e9ment brune, parsem\u00e9e de taches claires.<\/p>\n

  <\/p>\n

Pendant la belle saison, plusieurs g\u00e9n\u00e9rations se succ\u00e8dent en se chevauchant. Leur nombre est g\u00e9n\u00e9ralement de deux ou trois mais il peut atteindre quatre.
\nDes pics d’abondance des adultes marquent les g\u00e9n\u00e9rations successives.<\/p>\n

Apr\u00e8s l’accouplement, la femelle d\u00e9pose des \u0153ufs isol\u00e9s sur les feuilles des mauves ou des roses tr\u00e9mi\u00e8res.
\nLeur \u00e9closion intervient environ une semaine plus tard, au terme du d\u00e9veloppement embryonnaire<\/a>.
\nElle lib\u00e8re des chenilles<\/a> se nourrissant des feuilles de la plante h\u00f4te et grandissant \u00e0 la faveur de mues<\/a>.
\nApr\u00e8s trois \u00e0 quatre semaines, elles se transforment en chrysalides<\/a> au sein desquelles se produit la m\u00e9tamorphose<\/a>.
\nUne semaine \u00e0 dix jours plus tard, les adultes \u00e9mergent.<\/p>\n

L’Hesp\u00e9rie de l’alc\u00e9e passe l’hiver \u00e0 l’\u00e9tat de chenille.
\nLa derni\u00e8re ponte de l’ann\u00e9e est \u00e0 l’origine de chenilles entrant en diapause<\/a> \u00e0 l’automne. Leur d\u00e9veloppement est ralenti et ne reprend qu’au printemps suivant.<\/p>\n

\u00c0 la diff\u00e9rence des chenilles, les adultes se nourrissent du nectar des plantes herbac\u00e9es, qu’ils pr\u00e9l\u00e8vent \u00e0 l’aide d’une trompe.<\/p>\n
