Description
Oto Nakladal, Eliska Havrankova, and Vaclav Zumr test whether the liquid inside beetle traps skews counts of beetle diversity, in a study from 2023. Window traps are a standard way to sample beetles, and studies fill them with liquids such as beer, wine, or vinegar. If one liquid draws more beetles, studies that use unlike liquids may not be fairly compared.
Twenty four traps were set in sunny and shady spots, split across four liquids with plain water as the baseline. Over two summer months in 2021, close to thirty thousand invertebrates were caught, of which almost four thousand were beetles from 120 species. Counts of most groups were alike for beer and wine, and alike for vinegar and water. The liquid choice did shift some results, the authors warn.
