Les yeux de l’observateur de la nature ordinaire se posent fr\u00e9quemment sur des Insectes, abondants en termes d’esp\u00e8ces comme d’individus.<\/p>\n

S’ils sont relativement ais\u00e9s \u00e0 reconna\u00eetre, recouverts d’une cuticule articul\u00e9e (ce sont des Arthropodes), poss\u00e9dant six pattes ventrales (ce sont des Hexapodes) et g\u00e9n\u00e9ralement des ailes dorsales, il est plus d\u00e9licat de les identifier avec pr\u00e9cision.<\/p>\n

La premi\u00e8re \u00e9tape consiste \u00e0 d\u00e9terminer le sous-groupe (ou l’ordre) auquel appartiennent les sp\u00e9cimens rep\u00e9r\u00e9s.
\nIl est ensuite possible d’affiner l’identification en recherchant la famille, le genre voire l’esp\u00e8ce qu’ils repr\u00e9sentent.<\/p>\n

Morphologie des Insectes<\/h2>\n

Les ordres d’Insectes sont d\u00e9finis notamment sur la base de crit\u00e8res morphologiques.
\nIl s’agit de caract\u00e8res concernant la forme et les structures externes de l’animal.<\/p>\n

La figure ci-dessous repr\u00e9sente les principaux traits de la morphologie des Insectes.<\/p>\n
