Oak Processionary Moths found in Chobham

Oak processionary moths, a non-native species whose caterpillars can be harmful to people and animals and badly damage some species of oak trees by devouring the leaves, have been found in Chobham.

They were in pheromone traps on Surrey Heath Borough Council land at Chobham Meadows and are the first sign that the moth has spread from neighbouring boroughs.

The Surrey Heath Borough Council Tree Officer says the small, brown moths will inevitably lay eggs and spread further but the public can help the local authority get their colonies under control by reporting any signs that they are in local trees.

The signs to look out for are nests (white in colour during the height of the summer and then fading to brown) on the trunks of oak trees or on the ground and then, from next spring, the caterpillars that will hatch in March of April. 

Their distinctive characteristic, which is where they name comes from, is moving in nose-to-tail processions 

The key advice is to stay away from both the caterpillars and their nests, which will be full of caterpillar hairs, but to report any sightings immediately.

The fine hairs can cause skin rashes, and less commonly sore throats, breathing difficulties and eye problems.
