Description- Identification<\/span><\/h5>\n\n\n\n

Les m\u00e2les matures<\/strong> de Cordulia aenea, 47 \u00e0 55 mm, sont globalement sombres, le front est compl\u00e8tement noir, les yeux sont verts, le thorax vert bronze et velu. L’abdomen, dans la m\u00eame teinte, mais plus fonc\u00e9, sans marque claire \u00e0 l’exception d’un discret anneau jaune \u00e0 l’union des segments 2 et 3, il est largement dilat\u00e9 de fa\u00e7on sp\u00e9cifique en S7-S8.
On peut le confondre avec les repr\u00e9sentants du genre Somatochlora mais il est plus pr\u00e9coce, son abdomen distalement dilat\u00e9 est unique, il n’a pas de jaune sur le front, il ne montre qu’une seule nervure transverse avant le triangle<\/a>, l\u00e0 o\u00f9 les Somatochlora en montrent 2. Ses cerco\u00efdes<\/a> sont cylindriques, sans saillie notoire, la lame supra anale s\u00e9par\u00e9e en 2 lobes<\/a> (ici, on ne voit que le lobe droit), chacun portant 2 crochets, celle des Somatochlora est enti\u00e8re et non divis\u00e9e (ici S. metallica<\/a>).

Les femelles<\/strong> ont la m\u00eame coloration, mais pr\u00e9sente une tache jaune lat\u00e9rale sur S2 et une large tache tr\u00e8s claire <\/a>sur le c\u00f4t\u00e9 du S3, l’abdomen est massif, \u00e0 bord presque parall\u00e8les, et peu dilat\u00e9 distalement.
La lame vulvaire est peu visible, l\u00e0 o\u00f9 celle des Somatochlora fait une saillie spectaculaire (sauf S. arctica).

Habitat – Biotope<\/span><\/h5>\n\n\n\n

La Cordulie bronz\u00e9e est un habitant des eaux stagnantes de toutes sortes, les mares m\u00eame petites (la mienne !), les \u00e9tangs, les lacs, les gravi\u00e8res et les tourbi\u00e8res et il accepte parfois des eaux tr\u00e8s faiblement courantes.
C’est essentiellement une esp\u00e8ce de plaine, je l’ai cependant rencontr\u00e9 \u00e0 1150 m dans le Jura et il existe une observation record \u00e0 plus de 2700 m.<\/p>\n\n\n\n

Comportement – Ecologie<\/span><\/h5>\n\n\n\n

On observe le plus souvent les m\u00e2les en vol, parcourant inlassablement les berges d’une mare \u00e0 la recherche d’une femelle, pratiquant parfois de brefs vols stationnaires 50 cm ou 1 m\u00e8tre au -dessus de l’eau. Ils semblent se poser peu, et dans ce cas on les trouve un peu \u00e0 distance de l’eau. Les femelles sont discr\u00e8tes et sont peu vues en dehors des pontes qui se pratiquent en solo, en pleine eau (pas sur la v\u00e9g\u00e9tation) mais de temps en temps sous les branchages de la rive si les m\u00e2les sont nombreux et trop entreprenants. Je n’ai aper\u00e7u qu’une fois cette ponte, les accouplements sont plus commun\u00e9ment observ\u00e9s, dans les buissons \u00e0 quelque distance de l’eau, pendant \u00e0 une feuille ou un rameau.
Ils se nourrissent le long des bois ou des all\u00e9es foresti\u00e8res.
La vie larvaire dure 2 \u00e0 3 ans en plaine, 5 ans en montagne, 12 stades se succ\u00e8dent.<\/p>\n\n\n\n

Ph\u00e9nologie<\/span><\/h5>\n\n\n\n

Cordulia aenea est souvent le premier anisopt\u00e8re \u00e0 \u00eatre contact\u00e9 au printemps : il peut appara\u00eetre tout d\u00e9but avril pour dispara\u00eetre en septembre, mais il est beaucoup plus commun de la mi-mai \u00e0 la mi-juillet, avec d’importantes variations en fonction de la latitude et de l’altitude.<\/p>\n\n\n\n

Distribution g\u00e9ographique<\/span><\/h5>\n\n\n\n

On le rencontre \u00e0 peu pr\u00e8s partout en France, il est beaucoup moins commun sur la fa\u00e7ade m\u00e9diterran\u00e9enne et la c\u00f4te atlantique nord-ouest.
Il est essentiellement localis\u00e9 en Europe de l’Ouest, absent d’Espagne, mais pr\u00e9sent dans les iles britanniques et en Scandinavie. Il se rar\u00e9fie en allant vers l’est, voit sa distribution irr\u00e9guli\u00e8re et parsem\u00e9e, mais atteint le Japon !

\u00c9tymologie<\/span><\/h5>\n\n\n\n

Cordulia vient du mot grec kordyle<\/em> signifiant massue <\/em>ou gourdin<\/em> par allusion \u00e0 la forme de l’abdomen du m\u00e2le.
Aenea du latin aeneus<\/em>, adjectif signifiant –de bronze<\/em> pour insister sur l’\u00e9clat m\u00e9tallique de sa coloration.<\/p>\n\n\n\n
