Foraging behavior ofPachydiplax longipennis (Odonata: Libellulidae)

Journal of Insect Behavior, 1997
Food intake, prey availability, and prey capture behavior at feeding areas were quantified in the dragonflyPachydiplax longipennis by observing focal individuals on artificial perches, where they exhibited marked short-term site fidelity. Prey capture success was high and relatively constant, but the frequency and duration of feeding flights depended ...

Movement and Demographics ofLibellula fulva(Odonata, Libellulidae)

Environmental Entomology, 2008
Many capture-recapture studies on adult dragonflies have found male-biased sex ratios. However, few have estimated survivorship of males and females separately from data on frequency of recaptures in the field. Even when daily survival and capture probabilities are estimated separately, controversies can arise on whether sex biases in local survival ...

Hygroreceptors in the larva of Libellula depressa (Odonata: Libellulidae)

Journal of Insect Physiology, 2007
Ultrastructural and electrophysiological (single-cell recordings) investigations were carried out on the coeloconic sensilla borne by the apical antenna of the larvae of Libellula depressa (Odonata: Libellulidae). These sensilla appear as pegs located in pits.
