Geographic Range [top]
Range Description:
P. nodosus has an almost cosmopolitan distribution, apart from northern Europe to the north of the UK, the Netherlands and Lithuania in each of which it is rare. It also appears to be absent from Australia and New Zealand, although it is present on many Pacific Islands. It occurs east through at least the southern parts of Russia east to southern China and Japan, south through much of south and southeast Asia to Papua New Guinea. It is also widespread throughout much of Africa, north and south of the Sahara, the Middle East and the Indian Ocean Islands, throughout North America (except the extreme north; Alaska and northern Canada) south through Mexico, the West Indies and Central America to South America
In the Indo-Burma region, it has been recorded from Quangbinh in northern Viet Nam and in northern Thailand. It may be present in Lao PDR, but this is not certain.
