Le Hanneton de la Saint-Jean (Amphimallon solstitiale<\/em>) est un Insecte de l’ordre des Col\u00e9opt\u00e8res<\/a> et de la famille des M\u00e9lolonthid\u00e9s.<\/p>\n

L’adulte<\/a> est pr\u00e9sent principalement de juin \u00e0 juillet, voire en ao\u00fbt, et fr\u00e9quente les milieux secs (haies, prairies, jardins).
\nIl vole en particulier en fin de journ\u00e9e, \u00e0 proximit\u00e9 d’arbres \u00e0 feuilles caduques. <\/p>\n

  <\/p>\n

Dans nos r\u00e9gions, le Hanneton de la Saint-Jean est l’esp\u00e8ce de Hanneton la plus petite. La longueur de l’adulte est de l’ordre de 15 \u00e0 20 mm.<\/p>\n

De couleur brun verd\u00e2tre, il est ais\u00e9ment identifi\u00e9 \u00e0 la pr\u00e9sence des soies fauves qui couvrent son corps et notamment la r\u00e9gion ant\u00e9rieure de son thorax.<\/p>\n

  <\/p>\n

La reproduction intervient environ deux semaines apr\u00e8s que les adultes ont \u00e9merg\u00e9, de juin \u00e0 ao\u00fbt.<\/p>\n

Apr\u00e8s l’accouplement, la femelle d\u00e9pose une trentaine d’\u0153ufs dans le sol.<\/p>\n

Le d\u00e9veloppement embryonnaire<\/a> dure g\u00e9n\u00e9ralement un mois et conduit \u00e0 la lib\u00e9ration d’une larve<\/a>, correspondant \u00e0 un ver blanc, en ao\u00fbt ou septembre.<\/p>\n

Elle vit dans le sol, se nourrissant de racines, et grandit \u00e0 la faveur de mues<\/a>.<\/p>\n

Apr\u00e8s deux ans, elle se transforme en une nymphe<\/a> en mai-juin d’o\u00f9 \u00e9merge l’adulte.<\/p>\n

Celui-ci s’alimente des feuilles des arbres, arbustes et herbes.<\/p>\n
