The storm had passed and the light was fine, so we posed the moth before the camera several times. It was nervous business, for he was becoming restless, and every instant I expected him to fly, but of course we kept him guarded.
There was no hope of a female that late date, so the next step was to copy his colours and markings as exactly as possible. He was the gaudiest moth of my experience, and his name seemed to suit rarely well. Citheroma—a Greek poet, and Regalis—regal. He was truly royal and enough to inspire poetry in a man of any nation. His face-was orange-brown, of so bright a shade that any one at a glance would have called it red. His eyes were small for his size, and his antennae long, fine, and pressed against the face so closely it had to be carefully scrutinized to see them. A band of bright canary-yellow arched above them, his thorax was covered above with long silky, orange-brown hairs, and striped lengthwise with the same yellow. His abdomen was the longest and slenderest I had seen, elegantly curved like a vase, and reaching a quarter of an inch beyond the back wings, which is unusual. It was thickly covered with long hair, and faintly lined at the segments with yellow. The claspers were very sharp, prominent brown hooks. His sides were dotted with alternating red and orangebrown spots, and his thorax beneath, yellow. The under side of the abdomen was yellow, strongly shaded with orange-brown. His legs and feet were the same.
His fore-wings were a silvery lead colour, each vein covered with a stripe of orange-brown three times its width. The costa began in lead colour, and at half its extent shaded into orange-brown. Each front wing had six yellow spots, and a seventh faintly showing. Half an inch from the apex of the wings, and against the costa, lay the first and second spots, oblong in shape, and wide enough to cover the space between veins. The third was a tiny dot next the second. The hint of one crossed the next vein, and the other three formed a triangle; one lay at the costa about three-quarters of an inch from the base, the second at the same distance from the base at the back edge of the wing, and the third formed the apex, and fell in the middle, on the fifth space between veins, counting from either edge. These were almost perfectly round. The back wings were very hairy, of a deep orange-brown at the base, shading to lighter tones of the same colour at the edge, and faintly clouded in two patches with yellow.
Underneath the fore-wings were yellow at the base, and lead colour the remainder of their length. The veins had the orange-red outlining, and the two large yellow dots at the costa showed through as well as the small one beside them. Then came another little yellow dot of the same size, that did not show on the upper side, and then four larger round spots between each vein. Two of them showed in the triangle on the upper side full size, and the two between could be seen in the merest speck, if looked for very closely.
The back wings underneath were yellow three-fourths of their length, then next the abdomen began a quarter of an inch wide band of orange-brown, that crossed the wing to the third vein from the outer edge, and there shaded into lead colour, and covered the space to the margin. The remainder of the wing below this band was a lighter shade of yellow than above it. From tip to tip he measured five and a half inches, and from head to point of abdomen a little over two.
While I was talking Regalis, and delighted over finding so late in the season the only one I lacked to complete my studies of every important species, Arthur Fensler brought me a large Regalis caterpillar, full fed, and in the last stages of the two days of exercise that every caterpillar seems to take before going into the pupa state. It was late in the evening, so I put the big fellow in a covered bucket of soft earth from the garden, planning to take his picture the coming day. Before morning he had burrowed into the earth from sight, and was pupating, so there was great risk in disturbing him. I was afraid there were insects in the earth that would harm him, as care had not been taken to bake it, as should have been done.
A day later Willis Glendenning brought me another Regalis caterpillar. I made two pictures of it, although transformation to the pupa stage was so far advanced that it was only half length, and had a shrivelled appearance like the one I once threw away. I was disgusted with the picture at the time, but now I feel that it is very important in the history of transformation from caterpillar to pupa, and I am glad to have it.
Two days later, Andrew Idlewine, a friend to my work, came to the Deacon with a box. He said that he thought maybe I would like to take a picture of the fellow inside, and if I did, he wanted a copy; and he wished he knew what the name of it was. He had found it on a butternut tree, and used great care in taking it lest it 'horn' him. He was horrified when the Deacon picked it up, and demonstrated how harmless it was. This is difficult to believe, but it was a third Regalis and came into my possession at night again. My only consolation was that it was feeding, and would not pupate until I could make a picture. This one was six inches from tip to tip, the largest caterpillar I ever saw; a beautiful blue-green colour, with legs of tan marked with black, each segment having four small sharp horns on top, and on the sides an oblique dash of pale blue. The head bore ten horns. Four of these were large, an inch in length, coloured tan at the base, black at the tip. The foremost pair of this formidable array turned front over the face, all the others back, and the outside six of the ten were not quite the length of the largest ones.
The first caterpillar had measured five inches, and the next one three, but it was transforming. Whether the others were males and this a female, or whether it was only that it had grown under favourable conditions, I could not tell. It was differently marked on the sides, and in every way larger, and brighter than the others, and had not finished feeding. Knowing that it was called the 'horned hickory devil' at times, hickory and walnut leaves were placed in its box, and it evinced a decided preference for the hickory. As long as it ate and seemed a trifle larger it was fed. The day it walked over fresh leaves and began the preliminary travel, it was placed on some hickory sprouts around an old stump, and exposures made on it, or rather on the places it had been, for it was extremely restless and difficult to handle. Two plates were spoiled for me by my subject walking out of focus as I snapped, but twice it was caught broadside in good position.
While I was working with this caterpillar, there came one of my clearest cases of things that 'thrust themselves upon me.' I would have preferred to concentrate all my attention on the caterpillar, for it was worth while; but in the midst of my work a katydid deliberately walked down the stump, and stopped squarely before the lens to wash her face and make her toilet. She was on the side of the stump, and so clearly outlined by the lens that I could see her long wavering antennae on the ground glass, and of course she took two plates before she resumed her travels. I long had wanted a katydid for an illustration. I got that one merely by using what was before me. All I did was to swing the lens about six inches, and shift the focus slightly, to secure two good exposures of her in fine positions. My caterpillar almost escaped while I worked, for it had put in the time climbing to the ground, and was a yard away hurrying across the grass at a lively pace.
