The black arches or nun moth, Lymantria monacha, a small Palaearctic moth. They can be pests in a forest as they can consume 100 pine or 1000 spruce needles and twice as many are damaged by biting off. Spruces die at 70 percent needle loss and pine at 90 percent. #nature #moth #ecology #wildlife #photo #biology
