Resumen:
The natural history and mating behavior of a species of tephritid fruitfly in the poorly studied genus Haywardinaare described for the first time.Haywardina cuculiHendel larvae were recovered over four field seasons frominfested fruit of Vassobia breviflora(Sendtn.) Hunz, which constitutes a new host plant record for this species. Recovered pupae emerged as adults over 183 days on average, suggesting that most individuals became dormant. Adult flies engaged in sexual activity as soon as two days after emergence, were highlypromiscuous, and displayed large variability in copulation duration. As for mosttephritid species in the subtribe Carpomyini, H. cuculiexhibited a resourcedefense mating system. Fly activity peaked around noon. Copulation could lastfrom 9 min to 17 h, with most copulations beginning in the afternoon and lastinguntil the following day. We discuss the potential significance of copulationduration variability in light of mate guarding and sperm competition hypothesisand outline future research to understandthe evolution of life history and thesebehavioral strategies.
