\"Though representing a rather easy prey and being presumably exposed to their enemies without protection, the populations of the most Emperor moths (Saturniidae) seem to only undergo insignificant quantitative fluctuations within decades; despite some eventually measurable parasitic or meteorological\  influence they remain mostly stable in a long-term average. This may raise the question which mechanisms or survival strategies \– besides a high fertility,\  successful reproduction, mimicry or fast development \– ensure existence and continuance to seemingly so vulnerable species in a longer period. Herein some single species of predators seem to play decisive parts. In this contribution a few obsevations are described on the behaviour of the european blue jay Garrulus glandarius (Linnaeus, 1758) towards some separated, free living populations of the Japanese Oak Silkmoth Antheraea yamamai (Gu\érin-M\éneville, 1861) and some of its closer relatives, the results of which are compared by further tests with some more distant species of Saturniidae moths; the obtained
data indicate a reciprocal adaptation of behaviour in the predators and their preys \— and seem to generally correspond with an ecological and evolutionary relationship between the singing birds and butterflies, revealing some mechanisms of their reproductional and territorial behaviour.\"
