In our location there were three areas where the trees were full of Harlequin larva and pupa. On some trees there was litterally not one leaf with one or the other on it. They all dispersed on emergence and disappeared.
Belonging to the Colchester Natural History Society on a recent meeting I spoke to fellow members who had noted the lack of Harlequins in their various haunts.
I realise of course that they do hibernate and can cause problems in dwellings, but have not heard of mass hibernation in our locallity.
