oa Journal of the Entomological Society of Southern Africa - Directional calls and effects of turning behaviour in crickets
Previous reports of directional calling in crickets are confirmed for two tree crickets (Oecanthinae) and one bush cricket (Eniopterinae). These species also turn periodically while calling, causing the call intensity to fluctuate at any fixed point. The physical basis of directional calling is summarized, and some effects of turning behaviour are discussed.
