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
Ludwigia (plant) of †"Ludwigia collinsoniae" and †"Ludwigia corneri" have been described from middle Miocene strata of the Fasterholt area near Silkeborg in Central Jutland, Denmark. Ludwigia (plant) Ludwigia (primrose-willow, water-purslane, or water-primrose) is a genus of about 82 species of aquatic plants with a cosmopolitan but mainly tropical distribution. At current, there is much debate among botanists and plant taxonomists as to the classification of many "Ludwigia" species. Botanists from the US Department of Agriculture are currently doing genetic analyses on plants from the Western US and South America to better classify members of this genus. The genus was named by Carl
