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
Sky-blue poison frog Sky-blue poison frog The sky-blue poison frog ("Hyloxalus azureiventris") is a species of poison dart frog. It is endemic to Peru and known from the lower eastern versant of the Andes in the upper Amazon basin of the San Martín Region. The species has been placed in numerous genera, including the new genus "Cryptophyllobates" erected for it. However, it is now placed in "Hyloxalus"; although "Hyloxalus azureiventris" represents a distinct clade within "Hyloxalus", recognizing it formally would render the rest of "Hyloxalus" paraphyletic. Its main distinguishing feature is dorsolateral stripes that run down the back and end on the posterior.
