Abstract
This study surveys and attempts to interpret the different behavioral interactions between the solitary wasp Liris nigra V.d.L, and crickets of the species Gryllulus domesticus L. in different hunting situations. Significant variations are recorded, some of which are predictable, others not. Wasp-cricket interactions and responses become more frequent, vigorous and complete from onset to peak of the hunting phase. Discussion is concerned mainly with releasing conditions, with characteristics and possible meaning of the interactions and responses. The problem is placed in the context of general defense, alarm reactions, predator-prey interactions and possible corresponding behavioral adaptations.
