Oedaleus decorus

Here is a picture of Oedaleus decorus

This rare grasshopper, considered as extinct since the 1930s, was accidentally rediscovered in 1992 in the Valais Alps. We now use this model for running our field practical with conservation biology students. Data on population extension, abundance and species’ habitat requirements have been collected over the years, which enabled us to build a habitat suitability model. The yearly field practical enables us to keep an eye on this threatened species of Switzerland. More recently, we have investigated the genetic structure of this relict population, comparing it with other Palaearctic populations. This information will guide future translocation trials aimed at reinstalling the species where habitat is deemed suitable, based on our spatial model.
