在攻击和食用以马利筋（A.syriaca）种子为食的马利筋虫（O. fasciatus）后，螳螂心叶虫（Tenodera ardifolia sinensis）会反刍，并显示出被硬核内酯中毒的迹象，硬核内酯是昆虫从宿主植物中分离出来的次级物质。在几次相遇之后，螳螂完全拒绝攻击马利筋虫；它们甚至拒绝攻击以向日葵种子为食的美味无毒的筋膜虫，因为向日葵是一种缺乏心髓内酯的植物。这是第一次报道马利筋作为防御无脊椎动物捕食者的功效，也是第一次报道马利筋中提取的物质对昆虫的催吐潜力。
After attacking and consuming milkweed bugs (O. fasciatus) raised on seeds of milkweed (A.syriaca), the mantid Tenodera ardifolia sinensis regurgitates and shows signs of poisoning by cardenolides, secondary substances sequestered by the bugs from their host plants. After several encounters, mantids refuse to attack milkweed bugs altogether; they even refuse to attack palatable and non-toxic O. fasciatus raised on seeds of sunflower, a plant lacking cardenolides. This is the 1st report of the efficacy of automimicry as a defense against invertebrate predators, and the 1st report of emetic potential of substances derived from milkweed against insects.
