Clytre des saules ou Clytre lustr\u00e9 (Lyon, mai 2011)<\/figcaption><\/figure>\n

Les Clytres des saules (Clytra laeviscula<\/em>) sont particuli\u00e8rement nombreux ce printemps. Ils \u00e9voluent sur les feuilles, et parfois les fleurs, des v\u00e9g\u00e9taux dont ils nourrissent.<\/p>\n

Leur couleur rouge-orange permet de les rep\u00e9rer facilement, tout en constituant un signal d’avertissement aux \u00e9ventuels pr\u00e9dateurs. En effet, ces animaux contiennent des substances dont le go\u00fbt est d\u00e9sagr\u00e9able, qui les rendent immangeables.<\/p>\n

La reproduction du Clytre des saules intervient au mois de mai. Apr\u00e8s l’accouplement la femelle d\u00e9pose ses \u0153ufs isol\u00e9ment, chacun \u00e9tant enrob\u00e9 de produits de s\u00e9cr\u00e9tion et d’excr\u00e9ments, \u00e0 proximit\u00e9 d’une fourmili\u00e8re.
\nD\u00e9couvert par des fourmis, un \u0153uf est emport\u00e9 dans une fourmili\u00e8re o\u00f9 il \u00e9clot, lib\u00e9rant une larve.<\/p>\n

La larve s’alimente de vestiges de nourriture laiss\u00e9s par les fourmis, voire d’\u0153ufs et larves de fourmis. Ces derni\u00e8re r\u00e9cup\u00e8rent des mat\u00e9riaux de l’enveloppe que la femelle avait constitu\u00e9 autour de l’\u0153uf.
\nApr\u00e8s plusieurs mues permettant sa croissance, la larve se transforme en nymphe en automne, dans la partie sup\u00e9rieure de la fourmili\u00e8re. Au printemps suivant, l’adulte \u00e9merge.<\/p>\n

La dur\u00e9e du d\u00e9veloppement varie entre deux et quatre ans.<\/p>\n
