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 that caregivers for the captive animals struggle with. A chimera is not the same thing as a hybrid because it is a being composed of two or more genetically distinct cell lines in one entity. The entity does not exist as a member of a separate species but has differing elements inside of it. An animal that has experienced an organ transplant or related surgery involving tissues from a different species is an example. Throughout past human evolution, hybridization occurred in many different instances, such as cross-breeding between Neanderthals and ancient versions of what are now modern humans. Some scientists
