Separation of CHC profiles of the studied species by Non-metric Multidimensional Scaling. Coleoptera hunters (COLw) are indicated by circles, Hymenoptera hunters (HYMw) by squares and brood parasites by triangles. Similar hue colors are used to indicate host-brood parasites species pairs: orange (Cerceris arenaria / Hedychrum nobile), purple (C. interrupta / H. chalybaeum), yellow (C. quinquefasciata / H. niemelai), green (Philanthus coronatus and P. triangulum / H. rutilans), blue (C. rybyensis and C. sabulosa / H. gerstaeckeri). a Female brood parasites and their female hosts and b male brood parasites and their female hosts
