\"Accouplement<\/a>
C\u00e9toine dor\u00e9e, accouplement (Lyon, avril 2011 – G. Rigaud)<\/figcaption><\/figure>\n

  <\/p>\n

La C\u00e9toine dor\u00e9e (Cetonia aurata<\/em>) est un Insecte Col\u00e9opt\u00e8re<\/a> de la famille des C\u00e9toniid\u00e9s.<\/p>\n

Elle a fait l’objet de l’article de la semaine 14-2013<\/a>.<\/p>\n

  <\/p>\n

La reproduction de la C\u00e9toine dor\u00e9e d\u00e9bute au printemps, avec l’accouplement.
\nLa femelle d\u00e9pose ses \u0153ufs dans du bois en cours de d\u00e9composition, ou dans du compost, g\u00e9n\u00e9ralement en mai-juin.<\/p>\n

Le d\u00e9veloppement embryonnaire<\/a> dure une dizaine de jours. Les larves<\/a> \u00e9mergent des \u0153ufs d\u00e8s la fin du printemps ou au d\u00e9but de l’\u00e9t\u00e9.<\/p>\n

Elles se nourrissent de mati\u00e8re organique en d\u00e9composition ; leur r\u00e9gime alimentaire est qualifi\u00e9 de saproxylophage.<\/p>\n

Leur croissance est r\u00e9alis\u00e9e \u00e0 la faveur de mues<\/a>.
\nLe troisi\u00e8me stade larvaire, issu de la deuxi\u00e8me mue, passe g\u00e9n\u00e9ralement l’hiver.<\/p>\n

Au printemps suivant, la larve forme une coque en agglom\u00e9rant des particules de bois ou de terre.
\nAu sein de cet abri, elle se transforme en nymphe<\/a> et se m\u00e9tamorphose<\/a> durant l’\u00e9t\u00e9.<\/p>\n

L’adulte<\/a> peut \u00e9merger en fin d’\u00e9t\u00e9 ou au printemps suivant. Dans le premier cas, il passe l’hiver dans de vieilles souches d’arbres.<\/p>\n

Le d\u00e9veloppement post-embryonnaire<\/a> s’\u00e9tend ainsi g\u00e9n\u00e9ralement sur deux ans et les adultes rencontr\u00e9s un \u00e9t\u00e9 peuvent avoir pass\u00e9 l’hiver pr\u00e9c\u00e9dent ou provenir de nymphes de l’ann\u00e9e.<\/p>\n
