We sought to elucidate the ecological interactions of perhaps the least known life\u2010stage of the butterflies: that of the egg with its host plant. We recorded oviposition location and egg survival rates for\n                    <jats:italic>Troides helena, Troides amphrysus<\/jats:italic>\n                    and\n                    <jats:italic>Pachliopta antiphus<\/jats:italic>\n                    on their host plants\n                    <jats:italic>Aristolochia acuminata<\/jats:italic>\n                    and\n                    <jats:italic>Aristolochia cf. foveolata<\/jats:italic>\n                    through systematic monitoring of the Poring Butterfly Garden (Sabah, Malaysia). Here, we make the first observation of hypersensitive response (HR)\u2010like cell death and neoplasm formation in response to butterfly eggs deposited on\n                    <jats:italic>Aristolochia<\/jats:italic>\n                    leaves. This represents the first documented case of such egg\u2010killing traits in the highly diverse Magnoliids (&gt;\u200910,000 spp.). HR\u2010like cell death under eggs showed a statistically significant negative effect on butterfly egg survival. Additionally, we provide a quantitative overview of the oviposition sites selected by Troidini, establishing that up to 37.6% of eggs are not oviposited on the host plant. Together, this suggests a fitness cost to butterflies and a possible behavioral avoidance mechanism. These findings on egg\u2010killing and oviposition behavior provide a significant contribution to the study of coevolutionary interactions between Troidini and\n                    <jats:italic>Aristolochia<\/jats:italic>\n                    . Furthermore, these observations provide valuable information for butterfly gardens and conservation projects, where egg\u2010killing by host plants may significantly impact butterfly survival. Overall, this research provides a unique egg\u2010based perspective on the ecological interactions between Troidini and their host plants.\n                  <\/jats:p>","DOI":"10.1002\/ece3.74426","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T23:29:36Z","timestamp":1790724576000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Vengeful Vines: Cell Death and Neoplasm Formation in Aristolochia (Aristolochiaceae, Piperales) in Response to Oviposition of Troidini (Papilionidae, Lepidoptera) Butterflies"],"prefix":"10.1002","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-4905-9350","authenticated-orcid":false,"given":"Veerle","family":"van Beeck","sequence":"first","affiliation":[{"name":"Biosystematics Group Wageningen University &amp; Research  Wageningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justinah","family":"Parantis","sequence":"additional","affiliation":[{"name":"Research and Education Division Poring Butterfly Farm Sabah Parks  Kota Kinabalu Sabah Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-6558-7152","authenticated-orcid":false,"given":"Berber E.","family":"Zandstra","sequence":"additional","affiliation":[{"name":"Biosystematics Group Wageningen University &amp; Research  Wageningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-8907-1989","authenticated-orcid":false,"given":"Tjomme","family":"Fernhout","sequence":"additional","affiliation":[{"name":"Biosystematics Group Wageningen University &amp; Research  Wageningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9529-4114","authenticated-orcid":false,"given":"Arthur","family":"Chung","sequence":"additional","affiliation":[{"name":"Sabah Forestry Department Forest Research Centre  Sandakan Sabah Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-9748-3129","authenticated-orcid":false,"given":"Nazirah","family":"Mustaffa","sequence":"additional","affiliation":[{"name":"Institute for Tropical Biology &amp; Conservation University Malaysia Sabah  Kota Kinabalu Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0841-3144","authenticated-orcid":false,"given":"Nina E.","family":"Fatouros","sequence":"additional","affiliation":[{"name":"Biosystematics Group Wageningen University &amp; Research  Wageningen the Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6054-4032","authenticated-orcid":false,"given":"Corn\u00e9 F.
