  <\/p>\n

L’Agrion \u00e9clatant (Calopteryx splendens<\/em>) est un Insecte du groupe des Odonates<\/a> qui englobe Demoiselles et Libellules.<\/p>\n

Cette esp\u00e8ce est rencontr\u00e9e \u00e0 proximit\u00e9 des canaux et des rivi\u00e8res dont le courant est lent.<\/p>\n

  <\/p>\n

L’Agrion \u00e9clatant m\u00e2le est ais\u00e9ment reconnu \u00e0 la couleur m\u00e9tallique et brillante de son corps, vert bleu, par ailleurs fin et long.<\/p>\n

Il poss\u00e8de deux paires d’ailes semblables, larges et membraneuses, portant de vastes taches color\u00e9es.
\nAu repos, elles sont le plus souvent dress\u00e9es au dessus du corps et jointives. Cette particularit\u00e9 est une des caract\u00e9ristiques qui distingue les Demoiselles (Zygopt\u00e8res) des Libellules (Anisopt\u00e8res).<\/p>\n

\u00c0 l’avant, la t\u00eate est beaucoup plus large que longue, et porte deux yeux volumineux tr\u00e8s \u00e9cart\u00e9s, souvent de couleur brune.<\/p>\n

  <\/p>\n

L’Agrion \u00e9clatant, ainsi que les autres Odonates, est un pr\u00e9dateur.<\/p>\n

Adulte, il se nourrit de proies, en particulier d’Insectes. Il les rep\u00e8re, depuis un support v\u00e9g\u00e9tal, puis les capture en vol \u00e0 l’aide de ses pattes et pi\u00e8ces buccales.
\nIl se pose \u00e0 nouveau et d\u00e9guste alors la proie captur\u00e9e.<\/p>\n

  <\/p>\n

La reproduction implique un accouplement pendant lequel le m\u00e2le transf\u00e8re un spermatophore, petite poche contenant des spermatozo\u00efdes, \u00e0 la femelle.
\nM\u00e2le et femelle adoptent \u00e0 cette occasion une position rappelant un c\u0153ur, qu’\u00e9voque l’expression c\u0153ur copulatoire employ\u00e9e pour d\u00e9signer cette figure.<\/p>\n

La femelle d\u00e9pose alors les \u0153ufs f\u00e9cond\u00e9s sur ou dans des plantes aquatiques.
\nAu terme du d\u00e9veloppement embryonnaire, les \u0153ufs lib\u00e8rent des larves aquatiques qui grandissent \u00e0 la faveur de mues larvaires avant de sortir de l’eau et de se transformer en adulte par une mue imaginale.<\/p>\n
