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
Golden poison frog semiopaca", "C. rugiceps" and "C. sp. A". Other related toxins, histrionicotoxin and pumiliotoxin, are found in frog species from the genus "Dendrobates". The golden poison frog, like most other poisonous frogs, stores its poison in skin glands. Due to their poison, the frogs are deterrent to predators; "P. terribilis" poison probably kills any predator, except for one snake species, "Liophis epinephelus". This snake may be resistant to the frog's poison, but is not immune (Myers & Daly, 1978). The poisonous frogs and birds themselves are perhaps the only creatures to be immune to this poison. Batrachotoxin attacks the sodium channels
