Pine processionary Pine processionary The pine processionary ("Thaumetopoea pityocampa") is a moth of the family Thaumetopoeidae. Sometimes placed in the genus "Traumatocampa", it is one of the most destructive species to pines and cedars in Central Asia, North Africa and the countries of southern Europe. The urticating hairs of the caterpillar larvae cause harmful reactions in humans and other mammals. The species is notable for the behaviour of its caterpillars, which overwinter in tent-like nests high in pine trees, and which proceed through the woods in nose-to-tail columns, protected by their severely irritating hairs, as described by the French entomologist Jean-Henri Fabre.
Human–animal hybrid in the U.S. Congress, several scientists have argued that legal barriers might go too far and prohibit medically beneficial studies into human modification. Although the two topics are not strictly related, the debates involving the creation of human-animal hybrids have paralleled that of the debates around the stem-cell research controversy. The question of what line exists between a 'human' being and a 'non-human' being has been a difficult one for many researchers to answer. While animals having one percent or less of their cells originally coming from humans may clearly appear to be in the same boat as other animals,
