Figure 1 from: Klopfstein S, Riedel M, Schwarz M (2019) Checklist of ichneumonid parasitoid wasps in Switzerland (Hymenoptera, Ichneumonidae): 470 species new for the country and an appraisal of the alpine diversity. Alpine Entomology 3: 51-81. https://doi.org/10.3897/alpento.3.31613

Figure 1 Occurrence data of the family Ichneumonidae (1,878 species recorded from Switzerland) and butterflies and zygaenid moths (226 species). The better-covered areas on the left map mostly reflect the main excursion areas of different hymenopterists, which might or might not correspond to centres of ichneumonid diversity. Note that the scale of the colour code is exponential.
