As may be well imagined, Mr. Bignell with his lantern stealing up the side of a hedge in the night often enough routed the poachers and sent them flying, thinking they were being watched by a policeman. On one occasion he scared an owl. "I was enjoying myself, on my knees, hunting over the contents of my net that I had used for sweeping the low foliage, to see what captures I had made. My nose and bull's-eye lantern were thrust close to the ground, to prevent anything escaping observation. In the midst of this occupation an owl swooped down to see what was up, when I turned my lantern on him, and away he flew in a mighty hurry, bringing the back of his wings together with great force, like a man clapping his hands. He was evidently in great alarm, and uttered an unearthly scream. It certainly gave me also a turn, it was so sudden." All moths with highly pectinated antennæ, that is to say with their feelers comb-like at the extremities, have the most extraordinary power of scenting a female moth at a great distance, even two or three miles, with a favourable wind. Mr. Bignell says: "I once had a virgin female of the Oak-egger moth, and was desirous of getting some males. I started off with the lady in a tin box, with a perforated zinc top, to give her air and allow her perfume to escape. I walked through the fields towards Milehouse to where was a turnstile; and at this spot lighted on a weary policeman resting. As it was a dull day, without any token of the sun breaking out, to attract butterflies for their usual gambols, the policeman jeeringly remarked that I had missed the right day. I replied that I thought not, and that I could collect as many as I desired, in fact, I could make them come to me. He laughed incredulously. I then took out my tin box and placed it on the wall, and, magician-like, whistled and waved my hand. The policeman stared, and thought I was befooling him. But lo, in two or three minutes one male alighted close to the box, soon followed by others, and in a quarter of an hour I had at least fifty, and so tame that I picked them up with my fingers and distributed them among about a dozen people who had gathered to see what I was about. The policeman stared with open eyes and mouth, quite satisfied that my whistle and mysterious signs in the air with my hand had called the insects to me. Satisfied with what I had got I waved again and bade the moths depart, and clapped the box in my pocket. Next day I took the empty box out with me into the country. I had several males following me, and some actually penetrated into my pocket where was the empty box, proving that the perfume still remained in it, though wholly imperceptible to myself." On one occasion Mr. Bignell and a friend set out at night to find the beautiful moth _Heliophobus hispidus_, knowing its haunts, between the south side of the Plymouth citadel and the sea, where it is to be found in September or October resting on the grass.
