Abstract

The diel feeding behavior of four coexisting odonate larvae, Aeshna juncea, Coenagrion hastulatum, Cordulia aenea,and Leucorrhinia dubiawas studied in the laboratory. C. hastulatumand L. dubiawere equally active during day and night. While C. hastulatumconsumed an equal number of prey during day and night, L. dubiaconsumed more prey during night. In contrast, A. juncealarvae were most active and consumed more prey during day, while C. aenealarvae were most active and consumed more prey during night. In contrast to the other three species, A. junceashowed a longer reactive distance under light conditions. In A. junceaand L. dubiacapture efficiency was higher under light conditions, whereas in C. hastulatumand C. aeneait was the same irrespective of illumination. The results show that the time niche is an important component of the feeding in this guild.
