Cul de perce oreille : gros plan sur les pinces d\u2019un forficule<\/h1>\n

 <\/p>\n

\"macro<\/a>
Les deux \u00ab pinces \u00bb du perce oreille sont appel\u00e9es cerques. Leur forte courbure indique ici probablement un m\u00e2le — Guillaume Louyot<\/figcaption><\/figure>\n

Vu d\u2019aussi pr\u00e8s, l\u2019arri\u00e8re d\u2019un perce oreille prend une allure presque m\u00e9canique. Cette macro photographie montre les deux appendices en forme de pince situ\u00e9s \u00e0 l\u2019extr\u00e9mit\u00e9 de son abdomen. Leur nom scientifique : les cerques<\/strong>.<\/p>\n

Sur cet individu, les cerques sont particuli\u00e8rement courb\u00e9s et dent\u00e9s. Cette morphologie correspond tr\u00e8s probablement \u00e0 celle d\u2019un forficule m\u00e2le<\/strong>. Chez la femelle, les cerques sont g\u00e9n\u00e9ralement beaucoup plus droits.<\/p>\n

Comment s\u2019appellent les pinces du perce oreille ?<\/h2>\n

Ce que l\u2019on appelle couramment les pinces du perce oreille sont donc ses cerques. Ils constituent l\u2019un des caract\u00e8res les plus reconnaissables des forficules et expliquent en grande partie l\u2019apparence spectaculaire de l\u2019insecte lorsqu\u2019il est observ\u00e9 en macro photographie.<\/p>\n

\u00c0 quoi servent les cerques du perce oreille ?<\/h2>\n

Ces appendices ne sont pas simplement d\u00e9coratifs. Le perce oreille peut les utiliser pour se d\u00e9fendre, lors des interactions avec ses cong\u00e9n\u00e8res et pendant la reproduction. Chez les m\u00e2les, leur forme et leur taille peuvent \u00eatre particuli\u00e8rement impressionnantes.<\/p>\n

Perce oreille m\u00e2le ou femelle ?<\/h2>\n

La forme des cerques donne un excellent indice. Chez le m\u00e2le, ils sont g\u00e9n\u00e9ralement tr\u00e8s courb\u00e9s. Chez la femelle, ils sont plus droits. La pince tr\u00e8s arqu\u00e9e visible sur cette photographie indique donc vraisemblablement un m\u00e2le.<\/p>\n

Pourquoi l\u2019appelle t on perce oreille ?<\/h2>\n

Son nom spectaculaire ne signifie pas que l\u2019insecte cherche \u00e0 percer les oreilles humaines. Plusieurs explications historiques existent, notamment la ressemblance de ses cerques avec d\u2019anciens instruments ou sa pr\u00e9sence dans certains fruits \u00e0 noyau.<\/p>\n
