Toxic moths that can cause itchy rashes, eye and throat infections and breathing difficulty are sweeping across the country, with members of the public urged to remain vigilant.
A number of oak trees in Derbyshire were confirmed to be infested with the oak processionary moth and a warning has been issued as the pest "poses a threat to both plant and human health".
The trees in the Long Eaton area are being treated and measures are being taken to prevent their potential spread, Derbyshire Live reports.
The oak processionary moth was first detected in Kew Gardens in South West London in 2006 after they were imported on oak from Europe. Action is being taken to try to find out how it has spread to Derbyshire, with sites in the surrounding area to be monitored over the coming weeks.
The caterpillars of the moth, which are visible until the end of July, are described as having blackheads and bodies covered in long hairs. They usually move nose-to-tail in a procession.
The long hairs have proteins that can cause itchy rashes, itchy eyes and throat irritation. They can also cause breathing difficulties in people and pets.
Their nests are normally the size of a tennis ball and are typically dome or teardrop-shaped. They are white when fresh, but soon become discoloured and brown.
Nicola Spence, UK chief plant health officer, said: "Oak processionary moth is an insect pest of oak trees and poses a threat to both plant and human health. We are taking swift and effective action to treat the infested trees and eradicate the pest from this area, and prevent further spread in the surrounding area.
"The Government takes the management of the moth very seriously and has a robust programme in place to reduce the level of pest prevalence and protect oak resource, whilst supporting landowners to manage the risks associated with the moth in the areas where it has been identified."
The pests feed on the leaves of several species of oak trees, which can cause the trees to lose leaves and limit their growth.
Anyone spotting the moth, should report it, with photos, on the TreeAlert portal. Alternatively, you can email opm@forestrycommission.gov.uk or call 0300 067 4442.
