Moths of the Limberlost - Part 10

Part 10

Only those interested as I was, and who have had similar experience, know how to sympathize. I had thought a crowbar would be required to open one of those screens! With sinking heart I hurried to my room. Joy! There was yet hope! The escaped moth was the only one that had emerged. The first thing was to fasten the screen, the next to live with the remaining coc.o.o.ns.

The following morning another, female appeared, and a little later a male.

The coc.o.o.ns were long, slender, closely leaf-wrapped and hung from stout spinning longer than the average leaf stem. The outside leaf covering easily could be peeled away as the spinning did not seem to adhere except at the edges. There was a thin waterproof coating as with Cecropia, then a little loose spinning that showed most at top and bottom, the leaf wrapping being so closely drawn that it was plastered against the body of the heavy inner case around the middle until it adhered. The inner case was smooth and dark inside and the broken pupa case nearly black.

The male and female differed more widely in colour and markings than any moths with which I had worked. At a glance, the male reminded me of a monster Mourning Cloak b.u.t.terfly. The front wings from the base extending over half the surface were a dark brownish black, outlined with a narrow escalloped line of clay colour of light shade. The black colour from here lightened as it neared the margin. At the apex it changed to a reddish brown tinge that surrounded the typical eye-spot of all the Attacus group for almost three-fourths of its circ.u.mference. The bottom of the eye was blackish blue, shading abruptly to pale blue at the top. The straggle M of white was in its place at the extreme tip, on the usual rose madder field. From there a broad clay-coloured band edged the wing and joined the dark colour in escallops.

Through the middle of it in an irregular wavy line was traced an almost hair-fine marking of strong brown. The back wings were darker than the darkest part of the fore-wings and this colour covered them to the margin, lightening very slightly. A clay-coloured band bordered the edge, touched with irregular splashes of dark brown, a little below them a slightly heavier line than that on the fore-wing, which seemed to follow the outline of the decorations.

Underneath, the wings were exquisitely marked, flushed, and shaded almost past description in delicate and nearly intangible reddish browns, rose madder on grey, pink-tinged brown and clay colour.

On the fore-wings the field from base to first line was reddish brown with a faint tinge of tan beside the costa. From this to the clay-coloured border my descriptive powers fail. You could see almost any shade for which you looked. There were greyish places flushed with scales of red and white so closely set that the result was frosty pink. Then the background would change to brown with the same over-decoration. The bottom of the eye-spot was dark only about one-fourth the way, the remaining three-fourths, tan colour outlined at the top with pale blue and black in fine lines.

The white M showed through on a reddish background, as did the brown line of the clay border. The back wings widespread were even lovelier. Beginning about the eighth of an inch from the top was a whitish line tracing a marking that when taken as a whole on both outspread wings, on some, slightly resembled a sugar maple leaf, and on others, the perfect profile of a face. There was a small oblong figure of pinkish white where the eye would fall, and the field of each s.p.a.ce was brownish red velvet. From this to the clay-coloured band with its paler brown markings and lines, the pink and white scales sprinkled the brown ground; most of the pink, around the marking, more of the white, in the middle of the s.p.a.ce; so few of either, that it appeared to be brown where the clay border joined.

The antennae were shaped as all of the Attacus group, but larger in proportion to size, for my biggest Promethea measured only four and a quarter from tip to tip, and for his inches carried larger antlers than any Cecropia I ever saw of this measurement, those of the male being very much larger than the female. In colour they were similar to the darkest part of the wings, as were the back of the head, thorax and abdomen. The hair on the back of the thorax was very long. The face wore a pink flush over brown, the eyes bright brown, the under thorax covered with long pinkish brown hairs, and the legs the same. A white stripe ran down each side of the abdomen, touched with a dot of brownish red wine colour on the rings. The under part was pinkish wine crossed with a narrow white line at each segment. The claspers were prominent and sharp.

The finishing touch of the exquisite creation lay in the fact that in motion, in strong light the red wine shadings of the under side cast an intangible, elusive, rosy flush over the dark back of the moth that was the mast delicate and loveliest colour effect I ever have seen on marking of flower, bird, or animal.

For the first time in all my experience with moths the female was less than the male.

Even the eggs of this mated pair carried a pinkish white shade and were stained with brown. They were ovoid in shape and dotted the screen door in rows. The tiny caterpillars were out eleven days later and proved to be of the kind that march independently from their sh.e.l.ls without stopping to feed on them. Of every food offered, the youngsters seemed to prefer lilac leaves; I remembered that they had pa.s.sed the winter wrapped in these, dangling from their twigs, and that the under wings of the male and much of the female bore a flushing of colour that was lilac, for what else is red wine veiled with white? So I promptly christened them, 'The Pride of the Lilacs.' They were said to eat ash, apple pear, willow, plum, cherry, poplar and many other leaves, but mine liked lilac, and there was a supply in reach of the door, so they undoubtedly were lilac caterpillars, for they had nothing else to eat.

The little fellows were p.r.o.nouncedly yellow. The black head with a grey stripe joined the thorax with a yellow band. The body was yellow with black rings, the a.n.a.l parts black, the legs pale greyish yellow. They made their first moult on the tenth day and when ready to eat again they were stronger yellow than before, with many touches of black. They moulted four times, each producing slight changes until the third, when the body took on a greenish tinge, delicate and frosty in appearance. The heads were yellow with touches of black, and the a.n.a.l shield even stronger yellow, with black. At the last moult there came a touch of red on the thorax, and of deep blue on the latter part of the body.

In spinning they gummed over the upper surface of a leaf and, covering it with silk, drew it together so that nothing could be seen of the work inside. They began spinning some on the forty-second, some on the forty-third day, when about three inches in length and plump to bursting. I think at a puncture in the skin they would have spurted like a fountain. They began spinning at night and were from sight before I went to them the following morning. So I hunted a box and packed them away with utmost care.

I selected a box in which some mounted moths had been sent me by a friend in Louisiana, and when I went to examine my coc.o.o.ns toward spring, to my horror I found the contents of the box chopped to pieces and totally destroyed. Pestiferous little 'clothes' moths must have infested the box, for there were none elsewhere in the Cabin. For a while this appeared to be too bad luck; but when luck turns squarely against you, that is the time to test the essence and quality of the word 'friend.' So I sat me down and wrote to my friend, Professor Rowley, of Missouri, and told him I wanted Promethea for the completion of this book; that I had an opportunity to make studies of them and my plate was light-struck, and house-moths had eaten my coc.o.o.ns. Could he do anything?

To be sure he could. I am very certain he sent me two dozen 'perfectly good' coc.o.o.ns.

From the abundance of males that have come to seek females of this species at the Cabin, ample proof seems furnished that they are a very common Limberlost product; but I never have found, even when searching for them, or had brought to me a coc.o.o.n of this variety, save the three on one little branch found by Raymond, when he did not know what they were. Because of the length of spinning which these caterpillars use to attach their coc.o.o.ns, they dangle freely in the wind, and this gives them especial freedom from attack.

CHAPTER XV The King of the Poets: Citheronia Regalis

To the impetuosity of youth I owe my first acquaintance with the rarest moth of the Limberlost; "not common anywhere," say scientific authorities. Molly-Cotton and I were driving to Portland-town, ten miles south of our home. As customary, I was watching fields, woods, fence corners and roadside in search of subjects; for many beautiful coc.o.o.ns and caterpillars, much to be desired, have been located while driving over the country on business or pleasure.

With the magnificent independence of the young, Molly-Cotton would have scouted the idea that she was searching for moths also, but I smiled inwardly as I noticed her check the horse several times and scan a wayside bush, or stretch of snake fence. We were approaching the limits of town, and had found nothing; a slow rain was falling, and the shimmer on bushes and fences made it difficult to see objects plainly. Several times I had asked her to stop the horse, or drive close the fields when I was sure of a moth or caterpillar, though it was very late, being close the end of August; but we found only a dry leaf, or some combination that had deceived me.

Just on the outskirts of Portland, beside a gra.s.sy ditch and at the edge of a cornfield, grew a cl.u.s.ter of wild tiger lilies.

The water in the ditch had kept them in flower long past their bloomtime. On one of the stems there seemed to be a movement.

"Wait a minute!" I cried, and Molly-Cotton checked the horse, but did not stop, while I leaned forward and scanned the lilies carefully. What I thought I saw move appeared to be a dry lily bloom of an orange-red colour, that had fallen and lodged on the gra.s.ses against a stalk.

"It's only a dead lily," I said; "drive on."

"Is there a moth that colour?" asked Molly-Cotton.

"Yes," I replied. "There is an orange-brown species, but it is rare. I never have seen a living one."

So we pa.s.sed the lilies. A very peculiar thing is that when one grows intensely interested in a subject, and works over it, a sort of instinct, an extra sense as it were, is acquired. Three rods away, I became certain I had seen something move, so strongly the conviction swept over me that we had pa.s.sed a moth. Still, it was raining, and the ditch was wet and deep.

"I am sorry we did not stop," I said, half to myself, "I can't help feeling that was a moth."

There is where youth, in all its impetuosity, helped me. If the girl had asked, "Shall I go back?" in all probability I would have answered, "No, I must have been mistaken. Drive on!"

Instead, Molly-Cotton, who had straightened herself, and touched up her horse for a brisk entrance into town, said, "Well, we will just settle that 'feeling' right here!"

At a trot, she deftly cut a curve in the broad road and drove back. She drew close the edge of the ditch as we approached the lilies. As the horse stopped, what I had taken for a fallen lily bloom, suddenly opened to over five inches of gorgeous red-brown, canary-spotted wing sweep, and then closed again.

"It is a moth!" we gasped, with one breath.

Molly-Cotton cramped the wheel on my side of the carriage and started to step down. Then she dropped back to the seat.

"I am afraid," she said. "I don't want you to wade that ditch in the rain, but you never have had a red one, and if I bungle and let it escape, I never will forgive myself."

She swung the horse to the other side, and I climbed down.

Gathering my skirts, I crossed the ditch as best I could, and reached the lily bed, but I was trembling until my knees wavered.

I stepped between the lilies and the cornfield, leaned over breathlessly, and waited in the pelting rain, until the moth again raised its wings above its back. Then with a sweep learned in childhood, I had it.

While crossing the ditch, I noticed there were numbers of heavy yellow paper bags lying where people had thrown them when emptied of bananas and biscuits, on leaving town. They were too wet to be safe, but to carry the moth in my fingers would spoil it for a study, so I caught up and drained a big bag; carefully set my treasure inside, and handed it to Molly-Cotton. If you consider the word 'treasure' too strong to fit the case, offer me your biggest diamond, ruby, or emerald, in recompense for the privilege of striking this chapter, with its accompanying ill.u.s.tration, from my book, and learn what the answer will be.

When I entered the carriage and dried my face and hands, we peeped, marvelled, and exclaimed in wonder, for this was the most gorgeous moth of our collections. We hastened to Portland, where we secured a large box at a store. In order that it might not be dark and set the moth beating in flight, we copiously punctured it with as large holes as we dared, and bound the lid securely. On the way home we searched the lilies and roadside for a mile, but could find no trace of another moth. Indeed, it seemed a miracle that we had found this one late in August, for the time of their emergence is supposed to be from middle May to the end of June. Professor Rowley a.s.sures me that in rare instances a moth will emerge from a case or coc.o.o.n two seasons old, and finding this one, and the Luna, prove it is well for nature students to be watchful from May until October. Because these things happened to me in person, I made bold to introduce the capture of a late moth into the experience of Edith Carr in the last chapter of "A Girl of the Limberlost." I am pointing out some of these occurrences as I come to them, in order that you may see how closely I keep to life and truth, even in books exploited as fiction. There may be such incidents that are pure imagination incorporated; but as I write I can recall no instance similar to this, in any book of mine, that is not personal experience, or that did not happen to other people within my knowledge, or was not told me by some one whose word I consider unquestionable; allowing very little material indeed, on the last provision.

There is one other possibility to account for the moth at this time. Beyond all question the gorgeous creature is of tropical origin. It has made its way north from South or Central America.

It occurs more frequently in Florida and Georgia than with us, and there it is known to have been double brooded; so standing on the records of professional lepidopterists, that gives rise to grounds for the possibility that in some of our long, almost tropical Indiana summers, Regalis may be double brooded with us. At any rate, many people saw the living moth in my possession on this date.

In fact, I am prepared to furnish abundant proof of every statement contained in this chapter; while at the same time admitting that it reads like the veriest fairy tale 'ever thought or wondered.'

The storm had pa.s.sed 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 s.p.a.ce 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 s.p.a.ce 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 s.p.a.ce 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 b.u.t.ternut 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.
