Disagreement with a Paragraph Under Ecology Header

"It has been shown that these can sequester the plant's tropane alkaloids and store them through the pupal stage on to the adult butterfly, where they are then used as a defense mechanism, making themselves less palatable to vertebrate predators." I read the original source article, not just the source book given in the Wiki article ( reference 9), and it does not say that the tropane alkaloids are used as a defense mechansim by adult butterflies; it says that they are used as a defense mechanism by the larvae. Yes, the alkaloids are passed to the pupae and the adults, but in smaller and smaller quantities. I would summarize the findings as : "It has been shown that these larvae can sequester the plantʻs tropane alkaloids, where they are used as a defense mechanism, making the caterpillars less palatable to vertebrate predators." Here is the link to the source article:https://www.researchgate.net/profile/Andre-Freitas-18/publication/248023926_Tropane_and_pyrrolizidine_alkaloids_in_the_ithomiines_Placidula_euryanassa_and_Miraleria_cymothoe_Lepidoptera_Nymphalidae/links/558355b408ae4738295b7587/Tropane-and-pyrrolizidine-alkaloids-in-the-ithomiines-Placidula-euryanassa-and-Miraleria-cymothoe-Lepidoptera-Nymphalidae.pdf KATHERINE WAGNER-REISS (talk) 12:49, 2 June 2023 (UTC)
