The Yellow Emperor: Eacles Imperialis
Several years ago, Mr. A. Eisen, a German, of Coldwater, Michigan, who devotes his leisure to collecting moths, gave me as pinned specimens a pair of Eacles Imperialis, and their full life history. Any intimate friend of mine can testify that yellow is my favourite colour, with shades of lavender running into purple, second choice. When I found a yellow moth, liberally decorated with lavender, the combination was irresistible. Mr. Eisen said the mounted specimens were faded; but the living moths were beautiful beyond description. Naturally I coveted life.

I was very particular to secure the history of the caterpillars and their favourite foods. I learned from Mr. Eisen that they were all of the same shape and habit, but some of them might be green, with cream-coloured heads and feet, and black face lines, the body covered sparsely with long hairs; or they might be brown, with markings of darker brown and black with white hairs; but they would be at least three inches long when full grown, and would have a queer habit of rearing and drawing leaves to their mouths when feeding. I was told I would find them in August, on leaves of spruce, pine, cherry, birch, alder, sycamore, elm, or maple; that they pupated in the ground; and the moths were common, especially around lights in city parks, and at street crossings.
