Biotope or habitat preferences are important species characteristics that can be used for understanding their ecology, as well as their conservation, and even as a tool for crime investigations for detection of post-mortem body manipulation. However, the characterization of species- habitat preferences can be difficult. There are several limiting factors like lack of quantitative data and reliance on anecdotal evidence for this trait. Further, we must consider the reaction to the border between two neighboring hab...

The standard procedure for fluid preservation of insects consists of two steps. First, the specimen is killed and prepared in a fixative fluid and then transferred to a storage fluid. Recommendations for using specific chemicals or mixtures differ depending on the size and anatomy of the animal and vary among the authors. However, controlled comparative studies are often missing. The ideal method should preserve the specimen-s morphology as well as its genetic information. We have investigated the effect of 12 com...
