The following account is by Prof. E. W. Claypole in Psyche (iii, p. 463) : 



Several years ago I noticed, in the early part of May, that many of the leaves of 

 tb« Ohio buckeye, JEsculus glabra, drooped and withered very soon after they had 

 unfolded from the bud. For two or three years these drooping leaves caught my 

 attention. On gathering them I uniformly found a small hole in the leaf-stalk, from 

 ■which a tunnel, sometimes 12™™ in length, ran aloug the stalk. Above this hole the 

 leaf was dying, below it the stalk was still alive. In some few instances I found in 

 the tunnel a small yellowish caterpillar, evidently the author of the mischief. 

 Wherever the hole in the stalk was closed with droppings the caterpillar was present, 

 but whenever the hole was open the caterpillar was gone, leading to the inference 

 that it had escaped through the opening. 



In the early part of May, usually about the 2d or 3d, I found the drooping leaves 

 of the buckeye in great numbers. I gathered, May 8, a quantity of the leaves, and 

 among them, a single specimen in which the caterpillar was in the main stem of the 

 young shoot and not in the leaf-stalk — the only instance of the kiud that I have met 

 with. Taking the specimens home, I placed them under a bell glass in order to 

 determine the first point in doubt, the destination of the caterpillars after leaving 

 the leaf-stalk. Two days afterwards, on May 10, I found that the leaf stalks were all 

 -empty, and the caterpillars hidden in the faded leaf at the top of the stem, in which 

 they had previously burrowed. On May 15, five days later, the caterpillars were 

 still in the dead leaves, and I went to the trees to try and find some more specimens, 

 but was unsuccessful. However, on May 21, I found a few rolled-up leaves contain- 

 ing caterpillars, brought them home, and placed them with the others. 



On May 23, the surviving caterpillars were still feeding, but there were many dead 

 ones. 



On May 25 I found the first chrysalis among the leaves. It was light red in color, 

 with eight rings on the abdomen. The rolled-up leaf was lined inside with silk. 

 These facts show nothing in any way peculiar, and the same description would apply 

 to thousands of other chrysalids.
