Oak processionary
The oak processionary ''(Thaumetopoea processionea)'' is a moth whose caterpillars can be found in oak forests. They may pose a human irritant because of their poisonous setae (hairs), which may cause skin irritation and asthma.
== Distribution ==
The moths are widely distributed in central and southern Europe, and are occasionally found as far north as Sweden. In the southern countries of Europe the populations are controlled by natural predators, but these predators do not exist in northern Europe. Their range is expanding northward, possibly or partly as a result of global warming. The moth now has an established population in the UK. The eggs arrived on oak imported to the Richmond and Ealing areas of London in 2006 〔()〕
and the range of the species in the UK has been steadily expanding despite efforts to eradicate it. In 2013 the Forestry Commission announced helicopters would be deployed to "blanket spray woodland" where the caterpillars posed a health threat.
