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
Rockstone poison dart frog Rockstone poison dart frog The Rockstone poison dart frog ("Dendrobates nubeculosus") is a poorly known species of dendrobatid frogs endemic to Guyana. As it is known from only one specimen, very little information is currently available on "D. nubeculosus". It has been suggested to be one of the most poorly known species in the world. "D. nubeculosus" is a small to medium-sized poison dart frog; larger than many of its contemporary "Ranitomeya" species, but smaller than the other members of the genus "Dendrobates". The holotype specimen measures 2.5 centimetres in length, and the species' size range is unknown. It is
