Oecophoridae and Hawaii in an attempt to control the European gorse ("Ulex europaeus"), and the defoliating hemlock moth ("Agonopterix alstroemeriana") has been used against "Conium maculatum" poison hemlock in the United States. Oecophoridae Oecophoridae (concealer moths) is a family of small moths in the superfamily Gelechioidea. The phylogeny and systematics of gelechoid moths are still not fully resolved, and the circumscription of the Oecophoridae is strongly affected by this. Also possibly included is the Peruvian species "Auxotricha ochrogypsa", described by Edward Meyrick in 1931 as the sole member of its genus. In the past, the family was circumscribed more widely and
Poison dart frog by the relatively large size and high levels of toxicity of its members. Most species of poison dart frogs are small, sometimes less than in adult length, although a few grow up to in length. They weigh 1 oz. on average. Most poison dart frogs are brightly colored, displaying aposematic patterns to warn potential predators. Their bright coloration is associated with their toxicity and levels of alkaloids. For example, frogs of the genus "Dendrobates" have high levels of alkaloids, whereas "Colostethus" species are cryptically colored and are not toxic. Poison dart frogs are an example of an aposematic organism. Their
