Selection of Oviposition Sites by Libelloides coccajus (Denis & Schiffermüller, 1775) (Neuroptera: Ascalaphidae), North of the Alps: Implications for Nature Conservation

Figure 3

Vegetation cover on three different-sized concentric circles around the oviposition sites. (As plants may partly overlap, vegetation cover may be greater than 100%.) Boxes represent the interquartile range (IQR) including the median, whiskers being a maximum of 1.5 times the IQR. Values outside the whiskers’ range are shown as circles. Within a study area, samples sharing the same letters were not significantly different according to a pairwise Wilcoxon signed-rank tests for α = 0.05, corrected sensu Holm [37]. The acronyms of the study sites are explained in Table 1.
