Anax empereur femelle (Lyon, juillet 2012 – G. Rigaud)<\/figcaption><\/figure>\n

  <\/p>\n

L’Anax empereur (Anax imperator<\/em>) est un Insecte de l’ordre des Odonates<\/a>, du sous-ordre des Anisopt\u00e8res, et de la famille des Aeschnid\u00e9s.<\/p>\n

Il a fait l’objet de l’article de la semaine 10-2013<\/a>.<\/p>\n

La reproduction de cette esp\u00e8ce intervient \u00e0 la fin du printemps et en \u00e9t\u00e9.
\nApr\u00e8s l’accouplement, la femelle d\u00e9pose ses \u0153ufs \u00e0 l’int\u00e9rieur de v\u00e9g\u00e9taux flottants. Elle est \u00e0 cette occasion particuli\u00e8rement visible, comme sur l’image ci-dessus.<\/p>\n

Trois semaines plus tard, l’\u00e9closion des \u0153ufs lib\u00e8re des larves aquatiques. <\/p>\n

Celles-ci sont carnivores. Elles se nourrissent de larves de Moustiques, d’\u00c9ph\u00e9m\u00e8res, d’Odonates, de Phryganes ou encore de Punaises aquatiques.
\nElles rep\u00e8rent leurs proies \u00e0 la vue et poss\u00e8dent un \u00ab\u00a0masque\u00a0\u00bb qu’elles peuvent projeter et qui leur permet de s’en saisir.<\/p>\n

  <\/p>\n

Le d\u00e9veloppement post-embryonnaire<\/a> dure g\u00e9n\u00e9ralement un an, parfois deux .
\nIl comporte une douzaine de mues \u00e0 la faveur desquelles l’individu grandit.<\/p>\n

Les larves passent l’hiver et les adultes \u00e9mergent en fin de journ\u00e9e ou pendant la nuit, d\u00e8s le printemps pour les \u0153ufs de pontes pr\u00e9coces et en \u00e9t\u00e9 pour les \u0153ufs des pontes tardives.<\/p>\n
