Agonopterix alstroemeriana with the dry weight of the leaf. However, oviposition was not correlated positively with the concentration of alkaloids in the poison hemlock, which varies widely among individual plants. Therefore, it is difficult to predict whether increased alkaloids in the plant would increase or decrease the use of the hemlock moth as a biological control. The effects that the alkaloids in "Conium maculatum" cause on the moth, both physiologically and behaviorally, are relatively unknown. Persons interested in the biological control capabilities of "A. alstroemeriana" see behavioral dependency on the host plant as an asset when using this moth as a biological
Yellow-banded poison dart frog sex. Uniquely, it is also the only poison dart frog to estivate during dry spells. Yellow-banded poison dart frogs reproduce sexually. The mother lays her fertilized eggs (zygotes) in a body of water. When they hatch, they are called tadpoles. Like all Dendrobatidae, "D. leucomelas" frogs secrete toxins from their skin, which they gain from eating certain unspecified arthropod prey. It is uncertain precisely which arthropods lend their toxicity to which genus of Dendrobatidae, but one such arthropod is thought to have been identified as a possible source of the toxin for Dendrobatidae "Phyllobates terribilis" (aka the golden poison frog),
