Roosting site selection in the damselfly species calopteryx haemorrhoidalis (Odonata: Calopterygidae)
At a small stream in S' France the damselfly species Calopteryx haemorrhoidalis (Vander Linden 1825) was observed to determine temporal patterns of activity. Activity began within 90 min afterExpand

Heavy Metal Accumulation by Baetis rhodani and Macrobenthic Community Structure in Running Waters of the N' Harz Mountains (Lower Saxony/FRG) (Ephemeroptera: Baetidae)
6 running waters on the N' slopes of the Harz Mountains were studied in respect to their benthic macroinvertebrate communities and to heavy metal concentrations (cadmium, lead, copper and zinc) inExpand

Anti-predator strategies in oviposition site selection of Pyrrhosoma nymphula (Zygoptera: Odonata)
SummarySelection of sites for oviposition when the risk of predation by green frogs was variable studied in tandems of the damselfly Pyrrhosoma nymphula. In the absence of predators the number ofExpand

Impact of predation by spiders on a territorial damselfly (Odonata: Calopterygidae)
SummaryPredation by orb-weaving spiders and crab spiders on the damselfly Calopteryx haemorrhoidalis was studied at a small stream in Southern France. One species of orb-weaving spider, LarinioidesExpand

Site-specific mate-finding strategies and oviposition behavior inCrocothemis erythraea (Brullé) (Odonata: Libellulidae)
Mate-finding strategies and adaptations in pre- and postcopulatory behaviors to avoid male disturbance were studied in Crocothemis erythraea at two different sites. At ponds without perch sites malesExpand

Diel pattern of activity, mating, and flight behaviour in Onychogomphus uncatus (Odonata: Gomphidae)
Abstract The behaviour of Onychogomphus uncatus, including flight and mating activity, was studied at a fast-flowing irrigation canal. During the day, males perched in sections of the canal with aExpand

Female aggregation in Platycypha caligata (odonata: chlorocyphidae): a tactic to evade male interference during oviposition
Abstract Females of the African damselfly Platycypha caligata (Selys) oviposit on barkless driftwood in streams. Territorial males perform conspicuous courtship displays at these sites. ApproachingExpand

SummaryTandem pairs of the libellulid dragonfly Sympetrum vulgatum always start oviposition with contact guarding directly over the surface of shallow water, where they are exposed to green frogsExpand

Copulation, oviposition site selection and predation risk in the dragonfly species Crocothemis erythraea (Odonata: Libellulidae)
In the libellulid dragonfly Crocothemis erythraea (Brulle 1832), FF show multiple matings with several MM during one visit of the reproductive site. They oviposite at various locations of the water.Expand

Interspecific competition in sympatric Sympetrum sanguineum (Müller) and S. flaveolum (L.) (Anisoptera: Libellulidae)
The importance of interspecific competition for limited resources in the evolutionof species differences and community organization in insects seems unclear (WIENS, 1977; SCHAEFER, 1981). InExpand
