In parasitoid insects, females are generally expected to avoid parasitizing hosts already parasitized by other females, called superparasitism, and this prediction has been broadly supported across numerous species. However, in the parasitoid wasp Melittobia australica, multiple females were observed ovipositing on the same host despite the presence of nearby unparasitized hosts in the field. In this study, we first analysed field data using randomization tests, and found that females strongly aggregated on particular hosts rather than distributing randomly across hosts. We then conducted la","pubDate":"2026-10-20","url":"https://www.biorxiv.org/content/10.64898/2026.10.13.758990v1?rss=1"},"indexado":"2026-10-20T17:30:28.766Z"}}
