Moths of the Limberlost: A Book About Limberlost Cabin

by Gene Stratton-Porter

In the sunshine and fresh air the male began to dry rapidly, and no doubt he understood the presence of his kind, for he was much more active than the females. He climbed the twig, walked the twine body pendent, and was so energetic that we thought we dared not trust him out of doors; but when at every effort to walk or fly he only attempted to reach the females, we concluded that he would not take wing if at liberty. By this time he was fully developed, and so perfect he would serve for a study.

I polished the lenses, focused anew on the tree, marked the limits of exposure, inserted a plate, and had everything ready. Then I brought out the female, Molly-Cotton walking beside me hovering her with a net. The moth climbed from the twig to the tree, and clung there, her wings spread flat, at times setting them quivering in a fluttering motion, or raising them. While Molly-Cotton guarded her I returned for the male, and found him with wings so hardened that could raise them above his back, and lower them full width.

I wanted my study to dignify the term, so I planned it to show the under wings of one moth, the upper of the other. Then the smaller antennae and large abdomen of the female were of interest. I also thought it would be best to secure the male with wings widespread if possible, because his colour was stronger, his markings more pronounced. So I helped the female on a small branch facing the trunk of the tree, and she rested with raised wings as I fervently hoped she would. The male I placed on the trunk, and with wide wings he immediately started toward the female, while she advanced in his direction. This showed his large antennae and all markings and points especially note worthy; being good composition as well, for it centred interest; but there was one objection. It gave the male the conspicuous place and made him appear the larger because of his nearness to the lens and his wing spread; while as a matter of fact, the female had almost an inch more sweep than he, and was bigger at every point save the antennae.

The light was full and strong, the lens the best money could buy, the plate seven by nine inches. By this time long practice had made me rather expert in using my cameras. When the advancing pair were fully inside my circle of focus, I made the first exposure. Then I told Molly-Cotton to keep them as nearly as possible where they were, while I took one breathless peep at the ground glass.

Talk about exciting work! No better focus could be had on them, so I shoved in another plate with all speed, and made a second exposure, which was no better than the first. Had there been time, I would have made a third to be sure, for plates are no object when a study is at all worth while. As a rule each succeeding effort enables you to make some small change for the better, and you must figure on always having enough to lose one through a defective plate or ill luck in development, and yet end with a picture that will serve your purpose.

Then we closed the ventilators and released the moths in the conservatory. The female I placed on a lemon tree in a shady spot, and the male at the extreme far side to see how soon he would find her. We had supposed it would be dark, but they were well acquainted by dusk. The next morning she was dotting eggs over the plants.

The other cocoons produced mostly female living moths, save one that was lost in emergence. I tried to help when it was too late; but cutting open the cocoon afterward proved the moth defective. The wings on one side were only about half size, and on the other little patches no larger than my thumb nail. The body was shrunken and weakly.

At this time, as I remember, Cecropia eggs were the largest I had seen, but these were larger; the same shape and of a white colour with a brown band. The moth dotted them on the under and upper sides of leaves, on sashes and flower pots, tubs and buckets. They turned brown as the days passed. The little caterpillars that emerged from them were reddish brown, and a quarter of an inch long.

I could not see my way to release a small army of two or three hundred of these among my plants, so when they emerged I held a leaf before fifty, that seemed liveliest, and transferred them to a big box. The remainder I placed with less ceremony, over mulberry, elm, maple, wild cherry, grape, rose, apple, and pear, around the Cabin, and gave the ones kept in confinement the same diet.

The leaves given them always were dipped in water to keep them fresh longer, and furnish moisture for the feeders. They grew by a series of moults, like all the others I had raised or seen, and were full size in forty-eight days, but travelled a day or two before beginning the pupa stage of their existence. The caterpillars were big fellows; the segments deeply cut; the bodies yellow-green, with a few sparse scattering hairs, and on the edge of each segment, from a triple row of dots arose a tiny, sharp spine. Each side had series of black touches and the head could be drawn inside the thorax. They were the largest in circumference of any I had raised, but only a little over three inches long.
