The food was not long in arriving. The first shoal of gnats, mosquitoes, and lady-birds, which Geronimo ignored, was very soon followed by the daddy-longlegs, the lacewing flies, the smaller moths, and some of the more robust beetles. Watching Geronimo's stalking tactics was quite an education. A lacewing or a moth, having spun round the lamp until it was dizzy, would flutter up and settle on the ceiling in the white cirle of lamplight printed there. Geronimo, hanging upside down in his corner, would stiffen. He would nod his head two or three times very rapidly, and then start to edge across the ceiling cautiously, millimetre by millimetre, his bright eyes on the insect in a fixed stare. Slowly he would slide over the plaster until he was six inches or so away from his prey, whereupon he stopped for a second and you could see his padded toes moving as he made his grip on the plaster more secure. His eyes would become more protuberant with excitement, what he imagined to be a look of blood-curdling ferocity would spread over his face, the tip of his tail would twitch minutely, and then he would skim across the ceiling as smoothly as a drop of water, there would be a faint snap, and he would turn round, an expression of smug happiness on his face, the lacewing inside his mouth with its legs and wings trailing over his lips like a strange, quivering walrus moustache. He would wag his tail vigorously, like an excited puppy, and then trot back to his resting place to consume his meal in comfort. He had incredibly sharp eyesight, for I frequently saw him spot a minute moth from the other side of the room, and circle the ceiling in order to get near enough for the capture.

His attitude towards rivals who tried to usurp his territory was very straightforward. No sooner had they hauled themselves over the edge of the sill and settled down for a short rest after the long climb up the side of the villa, than there would be a scuffling noise, and Geronimo would flash across the ceiling and down the wall, to land on the window-sill with a faint thump. Before the newcomer could make a move, Geronimo would rush forward and leap on him. The curious thing was that, unlike the other geckos, he did not attack the head or body of his enemy. He made straight for his opponent's tail, and seizing it in his mouth, about half an inch from the tip, he would hang on like a bulldog and shake it from side to side. The newcomer, unnerved by this dastardly and unusual mode of attack, immediately took refuge in the time-honoured protective device of the lizards: he would drop his tail and scuttle over the edge of the sill and down the wall to the zinnia bed as fast as he could. Geronimo, panting a little from the exertion, would be left standing triumphantly on the sill, his opponent's tail hanging out of his mouth and thrashing to and fro like a snake. Having made sure his rival had departed, Geronimo would then settle down and proceed to eat the tail, a disgusting habit of which I strongly disapproved. However, it was apparently his way of celebrating a victory, and he was not really happy until the tail was safely inside his bulging stomach.

Most of the mantids that flew into my room were fairly small. Geronimo was always eager to tackle them, but they were too quick for him. Unlike the other insects the mantids seemed unaffected by the lamplight: instead of whirling round and round drunkenly, they would calmly settle in a convenient spot and proceed to devour the dancers whenever they settled to regain their strength. Their bulbous eyes seemed just as keen as the gecko's, and they would always spot him and move hurriedly, long before he had crept within fighting range. The night of the great fight, however, he met a mantis that not only refused to fly away, but actually went to meet him, and it was almost more than he could cope with.

I had for some time been intrigued by the breeding habits of the mantids. I had watched the unfortunate male crouching on the back of a female who, with complete equanimity, was browsing on him over her shoulder. Even after his head and thorax had disappeared into the female's neat mouth his hinder end continued to do its duty. Having watched their rather savage love life, I was now very anxious to see the laying and hatching of the eggs. My chance came one day when I was in the hills and I came face to face, as it were, with an exceptionally large female mantis who was stalking regally through the grass. Her belly was distended, and I felt sure that she was expecting a happy event. Having paused, swaying from side to side on her slender legs, and surveyed me coldly, she continued on her way, mincing through the grass-stalks. I decided that the best thing to do would be to capture her so that she could lay her eggs in a box where I could watch over them in comfort. As soon as she realized that I was attempting to capture her, she whirled round and stood up on end, her pale, jade-green wings outspread, her toothed arms curved upwards in a warning gesture of defiance. Amused at her belligerence towards a creature so much bigger than herself, I casually caught her round the thorax between finger and thumb. Instantly her long, sharp arms reached over her back and closed on my thumb, and it felt as though half a dozen needles had been driven through the skin. In my surprise I dropped her and sat back to suck my wound: I found that three of the little punctures had gone really deep, and that, by squeezing, tiny drops of blood appeared. My respect for her increased; she was obviously an insect to be reckoned with. At the next attempt I was more cautious and used two hands, grabbing her round the thorax with one and holding on to her dangerous front arms with the other. She wiggled ineffectually, and tried to bite me with her jaws, lowering her evil little pointed face and nibbling at my skin, but her jaws were too weak to have any effect. I carried her home and imprisoned her in a large gauze-covered cage in my bedroom, tastefully decorated with ferns, heather, and rocks, among which she moved with light-footed grace. I christened her Cicely, for no obvious reason, and spent a lot of time catching butterflies for her, which she ate in large quantities and with apparently undiminishing appetite, while her stomach got bigger and bigger. Just when I was certain that at any moment she would lay her eggs, she somehow or other found a hole in her cage and escaped.

I was sitting in bed reading one night when, with a great whirring of wings, Cicely flew across the room and landed heavily on the wall, some ten feet away from where Geronimo was busily cleaning up the last bits of an exceptionally furry moth. He paused with bits of fluff adhering to his lips, and gazed in astonishment at Cicely. He had, I am sure, never seen such a large mantis before, for Cicely was a good half-inch longer than he was. Amazed by her size and taken aback by her effrontery at settling in his room, Geronimo could do nothing but stare at her for a few seconds. Meanwhile Cicely turned her head from side to side and looked about with an air of grim interest, like an angular spinster in an art gallery. Recovering from his surprise, Geronimo decided that this impertinent insect would have to be taught a lesson. He wiped his mouth on the ceiling, and then nodded his head rapidly and lashed his tail from side to side, obviously working himself up into a death-defying fury. Cicely took no notice at all, but continued to stare about her, swaying slightly on her long, slender legs. Geronimo slid slowly from the wall, gulping with fury, until about three feet away from the mantis he paused and shifted his feet in turn to make sure that his grip was good. Cicely, with well-simulated astonishment, appeared to notice him for the first time. Without changing her position she turned her head round and peered over her shoulder. Geronimo glared at her and gulped harder. Cicely, having surveyed him coolly with her bulging eyes, continued her inspection of the ceiling as if the gecko did not exist. Geronimo edged forward a few inches, and scuffled his toes once more, and the tip of his tail twitched. Then he launched himself forward, and a strange thing happened. Cicely, who up till then was apparently absorbed in the inspection of a crack in the plaster, leapt suddenly into the air, turned round, and landed in the same spot, but with her wings spread out like a cloak, reared up on her hindlegs, and curved both serviceable forefeet at the ready. Geronimo had not been prepared for this spiky reception, and he skidded to a halt about three inches away and stared at her. She returned his stare with one of scornful belligerence. Geronimo seemed a little puzzled by the whole thing; according to his experience the mantis should have taken flight and zoomed away across the room at his approach, and yet here she was standing on end, arms ready to stab, her green cloak of wings rustling gently as she swayed from side to side. However, he could not back out now, having got so far, so he braced himself and leapt in for the kill.
