Moths of the Limberlost Part 4

The eggs on the floor and curtains were guarded with care. They were dotted around promiscuously, and at first were clear and of amber colour, but as the little caterpillars grew in them, they showed a red line three fourths of the way around the rim, and became slightly depressed in the middle. The young emerged in thirteen days. They were nearly half an inch long, and were yellow with black lines. They began the task of eating until they reached the pupa state, by turning on their sh.e.l.ls and devouring all of them to the glue by which they were fastened.

They were given their choice of oak, alder, sumac, elm, cherry, and hickory. The majority of them seemed to prefer the hickory.

They moulted on the fifth day for the first time, and changed to a brown colour. Every five or six days they repeated the process, growing larger and of stronger colour with each moult, and developing a covering of long white hairs. Part of these moulted four times, others five.

At past six weeks of age they were exactly as Mr. Eisen had described them to me. Those I kept in confinement pupated on a bed of baked gravel, in a tin bucket. It is imperative to bake any earth or sand used for them to kill pests invisible to the eye, that might bore into the pupa cases and destroy the moths.

I watched the transformation with intense interest. After the caterpillars had finished eating they travelled in search of a place to burrow for a day or two. Then they gave up, and lay quietly on the sand. The colour darkened hourly, the feet and claspers seemed to draw inside, and one morning on going to look there were some greenish brown pupae. They shone as if freshly varnished, as indeed they were, for the substance provided to facilitate the emergence of the pupae from the caterpillar skins dries in a coating, that helps to harden the cases and protect them.

These pupae had burst the skins at the thorax, and escaped by working the abdomen until they lay an inch or so from the skins.

What a "cast off garment" those skins were! Only the frailest outside covering, complete in all parts, and rapidly turning to a dirty brown. The pupae were laid away in a large box having a gla.s.s lid. It was filled with baked sand, covered with sphagnum moss, slightly dampened occasionally, and placed where it was cool, but never at actual freezing point. The following spring after the delight of seeing them emerge, they were released, for I secured a male to complete my collection a few days later, and only grew the caterpillars to prove it possible.

There was a carnival in the village, and, for three nights the streets were illuminated brightly from end to end, to the height of Ferris wheels and diving towers. The lights must have shone against the sky for miles around, for they drew from the Limberlost, from the Canoper, from Rainbow Bottom, and the Valley of the Wood Robin, their winged creatures of night.

I know Emperors appear in these places in my locality, for the caterpillars feed on leaves found there, and enter the ground to pupate; so of course the moth of June begins its life in the same location. Mr. Pettis found the mated pair he brought to me, on a bush at the edge of a swamp. They also emerge in cities under any tree on which their caterpillars feed. Once late in May, in the corner of a lichen-covered, old snake fence beside the Wabash on the s.h.i.+mp farm, I made a series of studies of the home life of a pair of ground sparrows. They had chosen for a location a slight depression covered with a rank growth of meadow gra.s.s. Overhead wild plum and thorn in full bloom lay white-sheeted against the blue sky; red bud spread its purple haze, and at a curve, the breast of the river gleamed white as ever woman's; while underfoot the gra.s.s was obscured with ma.s.ses of wild flowers.

An unusually fine cl.u.s.ter of white violets attracted me as I worked around the birds, so on packing at the close of the day I lifted the plant to carry home for my wild flower bed. Below a few inches of rotting leaves and black mould I found a lively pupa of the Yellow Emperor.

So these moths emerge and deposit their eggs in the swamps, forests, beside the river and wherever the trees on which they feed grow. When the serious business of life is over, attracted by strong lights, they go with other pleasure seeking company, and grace society by their royal presence.

I could have had half a dozen fine Imperialis moths during the three nights of the carnival, and fluttering above buildings many more could be seen that did not descend to our reach. Raymond had such a busy time capturing moths he missed most of the joys of the carnival, but I truly think he liked the chase better. One he brought me, a female, was so especially large that I took her to the Cabin to be measured, and found her to be six and three quarter inches, and of the lightest yellow of any specimen I have seen.

Her wings were quite ragged. I imagined she had finished laying her eggs, and was nearing the end of life, hence she was not so brilliant as a newly emerged specimen. The moth proved this theory correct by soon going out naturally.

Choice could be made in all that plethora, and a male and female of most perfect colouring and markings were selected, for my studies of a pair. One male was mounted and a very large female on account of her size. That completed my Imperialis records from eggs to caterpillars, pupae and moths.

The necessity for a book on this subject; made simple to the understanding, and attractive to the eye of the ma.s.ses, never was so deeply impressed upon me as in an experience with Imperialis.

Molly-Cotton was attending a house-party, and her host had chartered a pavilion at a city park for a summer night dance. At the close of one of the numbers; over the heads of the laughing crowd, there swept toward the light a large yellow moth.

With one dexterous sweep the host caught it, and while the dancers crowded around him with exclamations of wonder and delight, he presented it to Molly-Cotton and asked, "Do you know what it is?"

She laughingly answered, "Yes. But you don't!"

"Guilty!" he responded. "Name it."

For one fleeting instant Molly-Cotton measured the company. There was no one present who was not the graduate of a commissioned high school. There were girls who were students at The Castle, Smith, Va.s.sar, and Bryn Mawr. The host was a Cornell junior, and there were men from Harvard and Yale.

"It is an Eacles Imperialis Io Polyphemus Cecropia Regalis," she said. Then in breathless suspense she waited.

"Shades of Homer!" cried the host. "Where did you learn it?"

"They are flying all through the Cabin at home," she replied.

"There was a tumbler turned over their eggs on the dining-room floor, and you dared not sit on the right side of the library window seat because of them when I left."

"What do you want with their eggs?" asked a girl.

"Want to hatch their caterpillars, and raise them until they transform into these moths," answered poor Molly-Cotton, who had been taught to fear so few living things that at the age of four she had carried a garter snake into the house for a playmate.

"Caterpillars!" The chorus arose to a shriek. "Don't they sting you?

Don't they bite you?"

"No, they don't!" replied Molly-Cotton. "They don't bite anything except leaves; they are fine big fellows; their colouring is exquisite; and they evolve these beautiful moths. I invite all of you to visit us, and see for yourselves how intensely interesting they are."

There was a murmur of polite thanks from the girls, but one man measured Molly-Cotton from the top curl of her head to the tip of her slippers, and answered, "I accept the invitation. When may I come?" He came, and left as great a moth enthusiast as any of us. This incident will be recognized as furnis.h.i.+ng the basis on which to build the ballroom scene in "A Girl of the Limberlost", in which Philip and Edith quarrel over the capture of a yellow Emperor. But what of these students from the great representative colleges of the United States, to whom a jumbled string made from the names, of half a dozen moths answered for one of the commonest of all?

CHAPTER V The Lady Bird: Deilephila Lineata

In that same country garden where my first Cecropia was found, Deilephila Lineata was one of my earliest recollections. This moth flew among the flowers of especial sweetness all day long, just as did the hummingbirds; and I was taught that it was a bird also--the Lady Bird. The little tan and grey thing hovering in air before the flowers was almost as large as the humming-birds, sipping honey as they did, swift in flight as they; and both my parents thought it a bird.

They did not know the humming-birds were feasting on small insects attracted by the sweets, quite as often as on honey, for they never had examined closely. They had been taught, as I was, that this other constant visitor to the flowers was a bird. When a child, a humming-bird nested in a honeysuckle climbing over my mother's bedroom window. My father lifted me, with his handkerchief bound across my nose, on the supposition that the bird was so delicate it would desert its nest and eggs if they were breathed upon, to see the tiny cup of lichens, with a brown finish so fine it resembled the lining of a chestnut burr, and two tiny eggs. I well remember he told me that I now had seen the nest and eggs of the smallest feathered creature except the Lady Bird, and he never had found its cradle himself.

Every summer I discovered nests by the dozen, and for several years a systematic search was made for the home of a Lady Bird.

One of the unfailing methods of finding locations was to climb a large Bartlett pear tree that stood beside the garden fence, and from an overhanging bough watch where birds flew with bugs and worms they collected. Lady Birds were spied upon, but when they left our garden they arose high in air, and went straight from sight toward every direction. So locating their nests as those of other birds were found, seemed impossible.

Then I tried going close the sweetest flowers, those oftenest visited, the petunias, yellow day lilies, and trumpet creepers, and sitting so immovably I was not noticeable while I made a study of the Lady Birds. My first discovery was that they had no tail.

One poised near enough to make sure of that, and I hurried to my father with the startling news. He said it was nothing remarkable; birds frequently lost their tails. He explained how a bird in close quarters has power to relax its muscles, and let its tail go in order to save its body, when under the paw of a cat, or caught in a trap.

That was satisfactory, but I thought it must have been a spry cat to get even a paw on the Lady Bird, for frequently humming-birds could be seen perching, but never one of these. I watched the tail question sharply, and soon learned the cats had been after every Lady Bird that visited our garden, or any of our neighbours, for not one of them had a tail. When this information was carried my father, he became serious, but finally he said perhaps the tail was very short; those of humming-birds or wrens were, and apparently some water birds had no tail, or at least a very short one.

That seemed plausible, but still I watched this small and most interesting bird of all; this bird that no one ever had seen taking a bath, or perching, and whose nest never had been found by a person so familiar with all outdoors as my father. Then came a second discovery: it could curl its beak in a little coil when leaving a flower.

A few days later I saw distinctly that it had four wings but I could discover no feet. I became a rank doubter, and when these convincing proofs were carried to my father, he also grew dubious.

"I always have thought and been taught that it was a bird," he said, "but you see so clearly and report so accurately, you almost convince me it is some large insect possibly of the moth family."

When I carried this opinion to my mother and told her, no doubt pompously, that 'very possibly' I had discovered that the Lady Bird was not a bird at all, she hailed it as high treason, and said, "Of course it is a bird!" That forced me to action. The desperate course of capturing one was resolved upon. If only I could, surely its feet, legs, and wings would tell if it were a bird. By the hour I slipped among those bloom-bordered walks between the beds of flaming sweet-williams, b.u.t.tercups, phlox, tiger and day lilies, Job's tears, hollyhocks, petunias, poppies, mignonette, and every dear old-fas.h.i.+oned flower that grows, and followed around the flower-edged beds of lettuce, radishes, and small vegetables, relentlessly trailing Lady Birds.

Pa.s.s after pa.s.s I made at them, but they always dived and escaped me. At last, when I almost had given up the chase, one went nearly from sight in a trumpet creeper. With a sweep the flower was closed behind it, and I ran into the house crying that at last I had caught a Lady Bird. Holding carefully, the trumpet was cut open with a pin, and although the moth must have been slightly pinched, and lacking in down when released, I clung to it until my mother and every doubting member of my family was convinced that this was no bird at all, for it lacked beak, tail, and feathers, while it had six legs and four wings. Father was delighted that I had learned something new, all by myself; but I really think it slightly provoked my mother when thereafter I always refused to call it a bird. This certainly was reprehensible. She should have known all the time that it was a moth.

The other day a club woman of Chicago who never in her life has considered money, who always has had unlimited opportunities for culture both in America and Europe, who speaks half a dozen languages, and has the care of but one child, came in her auto mobile to investigate the Limberlost. Almost her first demand was to see pictures. One bird study I handed her was of a brooding king rail, over a foot tall, with a three-foot wing sweep, and a long curved bill. She cried, "Oh! see the dear little hummingbird!"

If a woman of unlimited opportunity, in this day of the world, does not know a rail from a humming-bird, what could you expect of my little mother, who spoke only two languages, reared twelve l.u.s.ty children, and never saw an ocean.

So by degrees the Lady Bird of the garden resolved itself into Deilephila Lineata. Deile--evening; phila--lover; lineata--lined; the Lined Evening Lover. Why 'evening' is difficult to understand, for all my life this moth occurs more frequently with me in the fore and early afternoon than in the evening. So I agree with those entomologists who call it the 'white-lined morning-sphinx.'

It is lovely in modest garb, delicately lined, but exceedingly rich in colour. It has the long slender wings of the Sphingid moths, and in grace and tirelessness of flight resembles Celeus, the swallow of the moth family.

Its head is very small, and its thorax large. The eyes are big, and appear bigger because set in so tiny a head. Under its tongue, which is a full inch long, is a small white spot that divides, spreads across each eye, and runs over the back until even with the bases of the front wings. The top of the head and shoulders are olive brown, decorated with one long white line dividing it in the middle, and a shorter on each side. The abdomen is a pale brown, has a straight line running down the middle of the back, made up of small broken squares of very dark brown, touched with a tiny mark of white. Down each side of this small line extends a larger one, wider at the top and tapering, and this is composed of squares of blackish brown alternating with white, the brown being twice the size of the white. The sides of the abdomen are flushed with beautiful rosy pink, and beneath it is tan colour.

The wings are works of art. The front are a rich olive brown, marked the long way in the middle by a wide band of buff, shading to lighter buff at the base. They are edged from the costa to where they meet the back wings, with a line of almost equal width of darker buff, the lower edge touched with white. Beginning at the base, and running an equal distance apart from the costa to this line, are fine markings of white, even and clear as if laid on with a ruler.

The surprise comes in the back wings, that show almost entirely when the moth is poised before a flower. These have a small triangle of the rich dark brown, and a band of the same at the lower edge, with a finish of olive, and a fine line of white as a marginal decoration. Crossing each back wing is a broad band of lovely pink of deeper shade than the colour on the sides. This pink, combined with the olive, dark browns, and white lining, makes the colour scheme of peculiar richness.

Its antennae are long, clubbed, and touched with white at the tips.

The legs and body are tan colour. The undersides of the wings are the same as the upper, but the markings of brown and buffish pink show through in lighter colour, while the white lining resembles rows of tan ridges beneath. Its body is covered with silky hairs, longest on the shoulders, and at the base of the wings.

The eggs of the moth are laid on apple, plum, or woodbine leaves, or on grape, currant, gooseberry, chickweed or dock. During May and June around old log cabins in the country, with gardens that contain many of these vines and bushes, and orchards of bloom where the others can be found the Lined Evening Lover deposits her eggs.

The caterpillars emerge in about six days. The tiny ovoid eggs are a greenish yellow. The youngsters are pale green, and have small horns. After a month spent in eating, and skin casting, the full-grown caterpillar is over two inches long, and as a rule a light green. There are on each segment black patches, that have a touch of orange, and on that a hint of yellow. The horn increases with the growth of the caterpillar, can be moved at will, and seems as if it were a vicious 'stinger.' But there is no sting, or any other method of self-defence, unless the habit of raising the head and throwing it from side to side could be so considered. With many people, this movement, combined with the sharp horn, is enough, but as is true of most caterpillars, they are perfectly harmless. Some moth historians record a mustard yellow caterpillar of this family, and I remember having seen some that answer the description; but all I ever have known to be Lineata were green.
