Comment faciliter l'identification de l'entomofaune ? : Construction, évaluation et amélioration de clés d'identification numériques

Abstract : Digital identification keys are effective tools for identifying plants and animals, and are also used in citizen science programs. Accessible online, the Xper3 platform makes it possible to create biodiversity databases and to generate interactive identification keys.We investigated various approaches in order to facilitate the identification of French entomofauna, especially some insect taxa living in endangered environments, or having ecological and heritage significance: ladybirds and three orders of aquatic insects (dragonflies and damselflies, mayflies, stoneflies and beetles), at the larval and adult stages. For all these groups, we created seven digital identification keys that are reliable, intuitive and accessible to everybody, available online at the following address: infosyslab.fr/?q=fr/node/113. Thanks to the Xperience system that can to record details of the identifications made by the Xper3 key users, we surveyed the use of our key for odonate larvae and the ‘’Insects’’ key of the citizen science program on pollination Spipoll. We were able to better understand how these digital keys are used and what problems are encountered by their users. Areas for improvement were proposed to make identification keys more effective and easier to use. Our work also showed that the precision of digital identification keys increases when ecological data are integrated alongside morpho-anatomical characters. This addition is particularly relevant for young aquatic insect larvae, for which the identification at the species level can be impossible with morpho-anatomical data alone.
