Distribution spatiale des larves de trois espèces d'Anisoptères

Abstract : The interspecific and ontogenetic variations in the larval distribution of Aeshna cyanea, Anax imperator and Libellula depressa were estimated on the basis of monthly samples in a pond in Brittany, France. The aeshnids co-occurred, but L. depressa usually inhabits the shallow parts only. The younger A. cyanea instars tend to congregate. In the FO and F-l aeshnid instars, the spatial overlap index decreases from April to May. No relationship between larval age and water depth could be evidenced.
