Vengeful Vines: Cell Death and Neoplasm Formation in Aristolochia (Aristolochiaceae, Piperales) in Response to Oviposition of Troidini (Papilionidae, Lepidoptera) Butterflies

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
This study investigates the oviposition ecology of the iconic Troidini butterflies on their host plants of the genus Aristolochia in Sabah, where we made the first observation of HR‐like cell death and neoplasm formation in response to oviposition of Troidini, signifying the first such record in the entire Magnoliid clade (> 10,000 spp.).
