Significance of plant compartments as insect hibernation sites with respect to the arithmetic mean (± 95 % CI) of A the Shannon index B number of individuals and C number of species / morphotypes subdivided by mowing regime. Flower heads and stems are not found on mown meadows. Different capital letters indicate pairwise significant differences between plant compartments of unmown (dark grey) sampling sites, whereas asterisks indicate significant differences (* p < 0.05; ** p < 0.005; *** p < 0.001) between both the mowing regimes based on Tukey’s HSD post-hoc comparisons after linear mixed models. Shannon index (only significant results reported): p < 0.001; DF: 3,5; F-ratio: 8.3 (flower head – stem: p < 0.005, flower head – tuft: p < 0.001, flower head – leaves: p < 0.005). Unmown – mown testing: tuft: p < 0.005; DF: 1,873; F-ratio: 8.8. Number of Individuals (only significant results reported): p < 0.001; DF: 1,97; F-ratio: 4.1 (flower head – stem: p < 0.05, stem – tuft: p < 0.05). Unmown – mown testing: tuft: p < 0.05; DF: 1,301; F-ratio: 4.0. Leaves: p < 0.05; DF: 1,20; F-ratio: 5.0. Species/morphotypes: p < 0.05; DF: 1,93; F-ratio: 1.6. Unmown – mown testing: tuft: p < 0.05; DF: 1,303; F-ratio: 4.0. Leaves: p < 0.05; DF: 1,20; F-ratio: 5.0. n = 8.
