Conservation, Natural History, Nature Reserves Herald moth brightens a day of clipping path edges 11 July 2017 Ian Alexander Herald Moth on Netty’s glove, whirring its wings to warm up. Its food plants are Willow and Aspen; we found it under a Grey Poplar so that’s probably what it grew up on. We found another specimen a minute later. They were cold and groggy on this cool, rainy day. Clipping path edges: the ivy had grown over the edging poles, sometimes by a foot or so.
