Abstract

Quantitative surveys were carried out in two European fluvial lower valleys, in Rumania (DanubePlain) and in France (Val-de-Loire). Various sites were investigated by various collecting methods. Faunisticrichness is higher in Val-de-Loire whilst the diversity indices (Shannon and Hurlbert) show that the Plainof the Danube exhibits a significantly greater level of biodiversity. Seventeen species appear jointly insamples of the two valleys. The Plain of the Danube harbours characteristic Eurosiberian elements:Chrysopa dasyptera and Chrysopa hungarica, Val-de-Loire shows Westmediteranean ones: Dichochrysapicteti, D. inornata and Chrysoperla mediterranea. Concerning actual numbers of individuals, the Plain ofthe Danube is dwelt equally by chrysopids glyco-palynophagous and aphidophagous as adults (50/50 %) contrarily to Val-de-Loire which is essentially by glyco-palynophagous species (98 %),overwintering as adults (89 %) or larvae (9 %).
