Le complexe Chrysoperla carnea en Belgique (Neuroptera : Chrysopidae)

Abstract

De 1997 à 2002, près de 4000 Chrysoperla carnea sensu lato furent collectées dans quinze localités de Belgique, principalement dans la ville de Gembloux (Province de Namur). Le fauchage de la végétation à l’aide d’un filet représente le principal mode d’échantillonnage. Les individus capturés furent identifiés sur base des descriptions de Thierry et al. (1992), Duelli (1995, 1999 communication personnelle), ainsi que par comparaison, soit avec différents types morphologiques (de D. Thierry), soit à des individus identifiés sur base de leurs chants (par P. Duelli). Chrysoperla kolthoffi sensu Cloupeau (Ch.c.c.4. ou « motorboat » sensu Henry) constitue le taxon le plus représenté dans les différentes localités. Chrysoperla carnea sensu Cloupeau (« low motorboat » sensu Henry) est également souvent rencontrée abondamment, principalement en automne. Seule Chrysoperla lucasina Lacroix est observée plus rarement chaque année et dans chaque lieu. La fréquence saisonnière de Ch. carnea s.C. est variable. Ainsi, elle est relativement faible en été et elle augmente progressivement au cours de l’automne. A cette période, les proportions de Ch. kolthoffi diminuent tandis que le taux de Ch. lucasina reste stable.
