	Le monitoring des libellules et demoiselles réalisé dans dix rizières suisses en 2019 et 2020 a permis de mettre en évidence 42 espèces. Parmi celles-ci, 14 espèces se sont développées dans les champs, dont dix sont bivoltines (''[[Ischnura elegans]], [[Ischnura pumilio]], [[Anax ephippiger]], [[Anax imperator]], [[Anax parthenope]], [[Crocothemis erythraea]], [[Orthetrum albistylum]], [[Orthetrum brunneum]], [[Orthetrum cancellatum]], [[Sympetrum fonscolombii]]'') et quatre univoltines (''[[Sympecma fusca]], [[Sympetrum depressiusculum]], [[Sympetrum striolatum]], [[Sympetrum vulgatum]]''). La découverte d'exuvies de ''[[Sympetrum depressiusculum]], [[Sympetrum striolatum]]'' et ''[[Sympetrum vulgatum]]'' en juillet 2020 a permis de documenter leur développement et la survie des œufs lors de la récolte en octobre et de la préparation des parcelles pour le semis et la plantation en mai. Une émergence massive d'une deuxième génération d{{'}}''[[Anax ephippiger]]'' et de ''[[Sympetrum fonscolombii]]'' a été observée en 2019. Les estimations de population pour le site de Brugg s'élevaient à des milliers voire des dizaines de milliers d'individus, confirmant l'attractivité de cet habitat pour le développement des deux espèces migratrices en Europe centrale. Pour ''[[Anax ephippiger]]'', l'année 2019 correspond à l'un des plus grands afflux connus en Suisse et en Europe au cours des trente dernières années. Le développement avéré du Sympetrum depressiusculum dans la rizière de l'Ins suggère que les rizières ont une importance conservatoire pour cette espèce menacée.

	The dragonfly and damselfly monitoring carried out in ten [[Suisse\|Swiss]] paddy fields in 2019 and 2020 revealed 42 species. Of these, 14 species developed in the fields, of which ten are bivoltine (''[[Ischnura elegans]], [[Ischnura pumilio]], [[Anax ephippiger]], [[Anax imperator]], [[Anax parthenope]], [[Crocothemis erythraea]], [[Orthetrum albistylum]], [[Orthetrum brunneum]], [[Orthetrum cancellatum]], [[Sympetrum fonscolombii]]'') and four univoltine (''[[Sympecma fusca]], [[Sympetrum depressiusculum]], [[Sympetrum striolatum]], [[Sympetrum vulgatum]]''). The discovery of exuviae of ''[[Sympetrum depressiusculum]], [[Sympetrum striolatum]]'', and ''[[Sympetrum vulgatum]]'' in July 2020 documented their development and the survival of the eggs during the harvest in October and the preparation of the plots for sowing and planting in May. A mass emergence of a second generation of ''[[Anax ephippiger]]'' and ''[[Sympetrum fonscolombii]]'' was observed in 2019. Population estimates for the Brugg site amounted to thousands or even tens of thousands of individuals, confirming the attractiveness of this habitat for the development of both migratory species in Central Europe. For ''[[Anax ephippiger]]'', the year 2019 corresponds to one of the largest known influxes in [[Suisse\|Switzerland]] and Europe over the last thirty years. The proven development of ''[[Sympetrum depressiusculum]]'' in the rice field of Ins suggests that rice fields have a conservatory significance for this threatened species.
