What is Oak processionary moth (OPM)

Oak processionary moth caterpillars

The caterpillars of OPM infest oak trees, eating (defoliating) the leaves, weakening the tree and leaving it vulnerable to other threats.

OPM was first identified in London in 2006 and has spread to some surrounding counties including Surrey and other parts of south east England.

OPM moths spread by flying from one tree to the next. Normally they stay close to the tree they were on as a caterpillar.
