"Generally, most of the pests and diseases tend to come into South-East England and spread northwards. Here's one that might be moving in the opposite direction.""Generally, most of the pests and diseases tend to come into South-East England and spread northwards.

The study, co-ordinated by a team in Scotland, is looking for the public to help it understand how far the worm has spread, as well as what effect it is having on earthworms and other animals, such as moles that eat earthworms and beetles that predate on flatworms.The study, co-ordinated by a team in Scotland, is looking for the public to help it understand how far the worm has spread, as well as what effect it is having on earthworms and other animals, such as moles that eat earthworms and beetles that predate on flatworms.

Caterpillars of the non-native moth, which was first recorded in South-East England in 2002, tunnel through leaves of infested trees, causing them to turn autumnal brown, even in the middle of summer.Caterpillars of the non-native moth, which was first recorded in South-East England in 2002, tunnel through leaves of infested trees, causing them to turn autumnal brown, even in the middle of summer.
A scientific paper published in 2014, which used data gathered by participants in the Opal study, found that the pest had been recorded in most areas south of Newcastle. A scientific paper published in 2014 found that the pest had been recorded in most areas south of Newcastle.
