Gomphus simillimus m\u00e2le, Sort en Chalosse (France-40), 04\/07\/2020<\/figcaption><\/figure>\n\n\n\n
Description – Identification<\/span><\/h5>\n\n\n\n

Gomphus simillimus ressemble beaucoup \u00e0 son cousin Gomphus pulchellus<\/a> ; la diff\u00e9rence la plus \u00e9vidente au premier regard est la largeur des bandes noires ant\u00e9hum\u00e9rales, beaucoup plus grasses que celles de Gomphus simillimus. Ces bandes noires sont \u00e0 peu pr\u00e8s aussi larges que la bande jaune qu’elles encadrent, alors que pour Gomphus graslinii cette bande jaune est tr\u00e8s \u00e9troite, \u00e0 peine visible et parfois interrompue.
Il mesure 45 \u00e0 50 mm.<\/p>\n\n\n\n

Habitat<\/span><\/h5>\n\n\n\n

Ce sujet a \u00e9t\u00e9 d\u00e9couvert le long du Luy, petite rivi\u00e8re qui passe au pied du bourg de Sort en Chalosse (France – Landes) ; il s’agit d’une prairie<\/a> d’une vingtaine de m\u00e8tres de large sur 80 de long, bord\u00e9e d’un c\u00f4t\u00e9 par la rivi\u00e8re, de l’autre par une route assez fr\u00e9quent\u00e9e.
On le trouve le plus souvent sur les rivi\u00e8res m\u00eame larges, rarement sur les lacs ou mares. Sa vie larvaire dure 3 ans, sans doute 1 ou 2 ans de plus dans les zones les plus froides.<\/p>\n\n\n\n

Distribution g\u00e9ographique<\/span><\/h5>\n\n\n\n

En Europe, il est plus commun dans le sud-ouest de la France, m\u00eame si on peut le rencontrer en Espagne ou au Portugal.
Il est rare<\/em> en Maine-et-Loire ou il est vu tout de m\u00eame \u00e0 peu pr\u00e8s tous les ans, beaucoup plus commun donc plus au sud sur la fa\u00e7ade Atlantique ou la vall\u00e9e du Rh\u00f4ne.<\/p>\n\n\n\n

\u00c9tymologie<\/span><\/h5>\n\n\n\n

Gomphus<\/em> vient d\u2019un mot grec qui signifie cheville<\/em> ou boulon<\/em>, en r\u00e9f\u00e9rence \u00e0 la forme de l\u2019abdomen de la plupart des esp\u00e8ces, qui ressemble \u00e0 une cheville pour assembler les bateaux<\/em> (1).
Simillimus<\/em> est le superlatif du latin similis, qui signifie similaire<\/em>, Gomphus simillimus est celui qui est le plus similaire <\/em>\u00e0 Gomphus pulchellus.<\/p>\n\n\n\n\n\n
