Many tents observed on mixed predominantly quickthorn/blackthorn hedge, though a few tents on bramble and oak. Active larvae found in the one tent I opened. Tents very tough. Leaves appeared to have been removed (browsed?) from above the tents. Larvae were never seen feeding outside the tents in daytime. Accumulations of frass within the tents. Larvae small (ca 10mm) and darkly coloured.
