  • Thank you for the report. Fortunately this is not oak processionary moth, instead it is most likely to be brown-tail moth (Euproctis chrysorrhoea), a long established species mostly found in southern England. The larvae are dark and hairy with a pair of distinct orangey 'warts' towards the rear end, and the white marks along their sides. They spend the winter as half grown caterpillars, before emerging in late-March/April once the weather warms up and the leaves of their host trees begin to flush. They feed on the leaves over the next few weeks before leaving the nest to pupate out of sight in May.

    Contact with the hairs on these caterpillars should be avoided as they can cause an itchy skin rash. These can be shed over the plant’s leaves and in the nests they build, and as such I would advise caution around them. They do not spread hairs over a wide distance, and as such there is little chance of being affected by the hairs if you don’t touch them.

    Many thanks for the enquiry.
