一些植物在受到机械刺激时迅速闭合叶片，但还没有发现机械刺激导致花瓣快速闭合的情况。在这项研究中，我们发现在用镊子对花萼、闭合的花或花葶进行实验刺激后，东海毛毡苔在2-10分钟内闭合花瓣。虽然花瓣关闭诱导更迅速地通过触摸更接近花的位置，它不是通过刺激雄蕊和雌蕊诱导。不同种类的茅膏菜花瓣闭合的习性不同：在实验刺激花萼或花葶后，D。tokaiensis和D. spatulata通常关闭的花瓣，但D. rotundifolia和D.丰明没有关闭它们。花瓣闭合可能起着防御专门食花动物的作用。
Some plants rapidly close their leaves in response to mechanical stimulation, but no case is known in which mechanical stimulation causes rapid petal closure. In this study, we found that Drosera tokaiensis closes petals within 2–10 min after experimental stimulation of the calyx, closed flowers or scapes with a pair of tweezers. Although petal closure was induced more rapidly by touching a position closer to a flower, it was not induced by stimulating stamens and pistils. The habit of petal closure varies among species of Drosera: after experimental stimulations of the calyx or scapes, D. tokaiensis and D. spatulata often closed petals but D. rotundifolia and D. toyoakensis did not close them. The petal closure may function as defense against a specialist florivore.
