Il existe un important dimorphisme sexuel entre la femelle parasite et le m\u00e2le libre.<\/p>\n
Alors que le corps du m\u00e2le poss\u00e8de l’organisation classique d\u2019un Insecte, de couleur brune, le corps de la femelle est vermiforme, d\u00e9pourvu d\u2019yeux compos\u00e9s, d\u2019antennes, de pattes et demeure entour\u00e9 de la derni\u00e8re exuvie larvaire.<\/p>\n
La t\u00eate du m\u00e2le porte une paire d’antennes volumineuses et des yeux compos\u00e9s saillants. Les pi\u00e8ces buccales sont de type broyeur mais r\u00e9duites.<\/p>\n
Son thorax est constitu\u00e9 d\u2019un prothorax et d\u2019un m\u00e9sothorax r\u00e9duits, le m\u00e9tathorax \u00e9tant bien d\u00e9velopp\u00e9 et pouvant repr\u00e9senter la moiti\u00e9 de la longueur du corps.
\nIl est muni de deux paires d’ailes, la premi\u00e8re \u00e9tant modifi\u00e9e en halt\u00e8res et la seconde large et membraneuse mais \u00e0 nervation r\u00e9duite.<\/p>\n
L’abdomen ne pr\u00e9sente pas de caract\u00e8re notable.<\/p>\n
<\/p>\n
Cycle de vie<\/h2>\n
Les m\u00e2les adultes \u00e9mergent alors que leur h\u00f4te est en vol. Ils recherchent d\u00e8s lors une femelle notamment gr\u00e2ce \u00e0 leurs antennes.<\/p>\n
Apr\u00e8s l’accouplement, les \u0153ufs r\u00e9alisent leur d\u00e9veloppement dans le corps de la femelle.
\nLeur \u00e9closion lib\u00e8re des larves de premier stade se d\u00e9pla\u00e7ant vers le t\u00e9gument de l\u2019h\u00f4te. Elles passent dans un autre h\u00f4te, probablement via les fleurs, puis dans une larve h\u00f4te.
\nL\u00e0, elles subissent une mue les transformant en forme apode. Elles s’alimentent \u00e0 partir de l\u2019h\u00e9molymphe de leur h\u00f4te.
\nElles r\u00e9alisent leur mue imaginale peu apr\u00e8s la transformation de la larve h\u00f4te en imago.<\/p>\n
Le d\u00e9veloppement post-embryonnaire fait intervenir jusqu’\u00e0 quatre stades larvaires, et dans le cas du m\u00e2le, un puparium est form\u00e9 sugg\u00e9rant l’existence d’une forme nymphale.<\/p>\n
Bien que tr\u00e8s modifi\u00e9 en relation avec le mode de vie parasitaire, le cycle de vie des Strepsipt\u00e8res pr\u00e9sente des caract\u00e9ristiques qui permettent de les qualifier d’Insectes holom\u00e9taboles (larve et m\u00e9tamorphose) et endopt\u00e9rygotes (\u00e9bauches d’ailes internes).<\/p>\n
