Caterpillar web infestation threatens town's street trees

A Midlands council has said it may have to remove street trees that are infested with caterpillar webs, even though the webs are harmless and the trees still apparently healthy.

Corby Borough Council said that the cherry trees, on the town's Cottingham Road, were infested with ermine moth (Yponomeuta sp.) larvae for a second year running, leaving them defoliated and covered in webs.

"These caterpillars are not hazardous to human health but can cause significant damage to trees long term which could result in them eventually needing to be removed," the council said in a statement.

"We are working with external consultants to see if there are any possible solutions to break the cycle of the caterpillars returning and will continue to monitor the situation."
