Thaumetopoea processionea (Linnaeus, 1758) - (oak processionary moth)
The moth is a defoliator of oak trees in Europe and surrounding regions. Its distribution range extends up to the southern parts of Sweden in the north and to southern parts of Russia and parts of western Asia in the east. Outbreaks can turn into a major health hazard. The barbed and toxic hairs of the caterpillars cause allergic reactions in humans. They break of easily and can become airborne, causing dermatitis as well as pharyngitis when inhaled.
