in the trees, since the leaves of both walnut and ailanthus are compound and it 

 would be impossible to encase the entire leaf stalk in silk. I have never been able 

 to obtain the pupae of Hyperchiria io in the woods. The chrysalids of the great 

 leopard moth Ecpantheria scribonia in its years of plenty may often be found 

 in numbers under the bark of old dead stumps. The pupae of hawk moths are 

 usually found by accident. In gardens where tomatoes and potatoes have been 

 cultivated and in tobacco patches, the jug-handled chrysalids of Celeus and Car- 

 olina are often spaded up in the Spring and quite plentifully in Southern sweet 

 potato patches, Macrosila cingulata. By turning over logs in the forest and prying 

 up flat rocks I have occasionally found chrysalids of Dolba hylaeus, Eacles im- 

 perialis and Citheronia regalis. The latter two the giants of all our Northern 

 chrysalids. The hairy cocoons of the woolly bears are often to be found under 

 boards and around sheds in our own back yards. I have found the chrysalids 

 of the red admiral in cupped leaves of the big-leafed nettle, suspended from the silk 

 iining of the leaf shelter, similarly in the narrow-leafed nettle and thistle in an in- 

 tricacy of leaves and webs I have found pupae of the painted lady. About hop 

 vines and elm sprouts, chrysalids of Interrogationis and comma are often found. 

 Under little shelters formed by drawing together and fastening with silk, the croton 

 leaves, pupae of Anaea andria are not rare in season. The pupae of Papilios are 

 occasionally found under shelter, as beneath a fence rail or a loose rock near the 

 foodplants. I once obtained chrysalids of the eight-spotted-forester when feeding 

 the larvae on grape leaves, by cutting corn cobs in inch lengths and placing in the 

 jars. The larvae bored into the pith and pupated there. 



The larvae of Catocala grynea are also borers, though they will spin on a 

 twig or stem by chewing the bark and spinning it into the cocoon. Ordinarily, 

 when handy, they bore into rotten wood and pupate. Perhaps polygama and 

 ultronia will do the same.
