Conium maculatum disturbed ground. It is used as a food plant by the larvae of some Lepidoptera species, including silver-ground carpet. The poison hemlock moth ("Agonopterix alstroemeriana") feeds on the plant during its larval stage. "A. alstroemeriana" has been widely used as a biological control agent for "C. maculatum". Poison hemlock flourishes in the spring, when most other forage is gone. All plant parts are poisonous, but once the plant is dried, the poison is greatly reduced, although not gone completely. The plant is poisonous to animals that graze on it. "Conium" contains the piperidine alkaloids coniine, N-methylconiine, conhydrine, pseudoconhydrine and gamma-coniceine
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.
