Observational study of grasshoppers(Orthoptera) on green roofs in northern Switzerland | JulieAnn Razryadov #greenroofs

It was interesting to observe such a diversity of grasshoppers on green roofs, with everything from the common Chorthippus biguttulus to the new find for Basel, Aiolopus thalassinus , but these data are hardly scratching the surface. However preliminary they may be, the results from this study are encouraging. At least one species was found on the majority of the roofs visited, which suggests that grasshoppers are able to colonize quickly, and in diverse habitats. Since the weather may have affected the low species count towards the end of August, it would be interesting to see whether earlier data collection (e.g. starting in June) would yield different results. If given more time, will more grasshoppers find this habitat and claim it as a suitable place to breed? To investigate such a question, an estimation of population sizes would be required. In order to rule out gra...
