Agonopterix alstroemeriana alkaloids obtained from its host plant. They also have the advantage of local predators being less familiar with the species because they are non-native. The caterpillar may also benefit from the toxic alkaloids present in the poison hemlock host plant because they may increase the ability of "A. alstroemeriana" to recognize "Conium maculatum" as the correct location for oviposition. They pupate for 2 weeks in the soil, usually from late May to early June. The color of pupa is red-brown, with fine hairs densely located. The length of pupae is approximately 6–7 mm. After pupating, the moths emerge from the
Cooperia (plant) Cooperia (plant) Cooperia was a genus of tender herbaceous perennials native to South America and the southern reaches of North America. They were closely related to "Zephyranthes" and "Habranthus", all of which are members of the amaryllis family, Amaryllidaceae. All three genera were commonly known as rain lilies because of their propensity for blooming after rains. "Cooperia" blooms in summer and fall.
