  • Acisoma trifidum <\/em>: 2 m\u00e2les observ\u00e9s pos\u00e9s (photos).<\/li>\n\n\n\n
  • Ceriagrion citrinum <\/em>: 14 m\u00e2les et 4 femelles (photos). Observation de tandems, dont certains sont proches d\u2019un contexte de ponte. Des m\u00e2les suppl\u00e9mentaires peuvent accompagner un tandem lorsque le couple se d\u00e9place et le suivre.<\/li>\n\n\n\n
  • Ceriagrion glabrum<\/em> : fourchette de 30 \u00e0 100 individus des deux sexes (photos). Observations de tandems et de pontes.<\/li>\n\n\n\n
  • Chalcostephia flavifrons <\/em>: 50 \u00e0 300 individus des deux sexes (photos). Les individus ont \u00e9t\u00e9 observ\u00e9s pos\u00e9s sur des v\u00e9g\u00e9taux ou en d\u00e9placement en vol. Cette esp\u00e8ce occupe aussi bien les herbiers d\u2019h\u00e9lophytes de lisi\u00e8re en contexte ombrag\u00e9 que lumineux.<\/li>\n\n\n\n
  • Chlorocypha curta <\/em>: un m\u00e2le en d\u00e9placement (en vol).<\/li>\n\n\n\n
  • Crocothemis sp. <\/em>: une femelle pos\u00e9e cf. erythraea<\/em> (photo : d\u00e9termination \u00e0 terminer).<\/li>\n\n\n\n
  • Pseudagrion hamoni <\/em>: 300 \u00e0 1000 individus. Observation de nombreux tandems voisins les uns des autres. On les voit par ailleurs en d\u00e9placement (en vol) ou proches d\u2019un contexte de ponte. L\u2019esp\u00e8ce vit en groupe, si bien que les individus vus isol\u00e9ment sont relativement peu nombreux. On les voit essentiellement au niveau des herbiers d\u2019h\u00e9lophytes de lisi\u00e8re ombrag\u00e9s \u00e0 quelques secteurs plus lumineux.<\/li>\n<\/ul>\n\n\n\n
