Extract

Intruding Oecanthus nigricornis (Walker) females stole nutritional glandular secretions from males engaged in post-copulatory behavior with their mates. This mating strategy may enhance female reproduction.

Mating behavior of Oecanthus spp. begins with elaborate male courtship involving vibratory, acoustic, and olfactory signalling. The female mounts the male, with copulation occurring soon after. During courtship and after copulation the female remains mounted and is provided with male metanotal glandular secretions. These nutritional secretions and the consumed spermatophore increase reproduction (Bell 1979; in press).
