72 CATERPILLARS AND THEIR MOTHS 



at the tip. The spiracles were deep blue-black, ringed 

 with palest blue. The anal shield had a yellow tip. 

 There were no oblique lines on the sides such as many 

 sphingid larvae have. The spiracles were very con- 

 spicuous. 



They were very hungry creatures, and there were a 

 good many of them, and before they were full fed 

 they ate every leaf of the Tatarian honeysuckle, and 

 began on a bush of Symphoricarpos racemosus, the 

 snowberry-bush, which is almost always found in old 

 gardens or by the front door of very old farm-houses. 

 They were not delicate at all, nor were any of them 

 stung, so we reared the whole boxful, though nearly 

 half of them lost the slender blue-black tips of their 

 caudal horns at some stage of their life. They reached 

 us in May, and on the 16th of June they stopped eat- 

 ing, emptied their intestines, and began hurrying 

 around the tins, growing purplish on their backs and 

 duller in color all over. When they tired of crawling, 

 or spinning-time had come, each spun a slight web, 

 holding leaves together, or fastening them to the bot- 

 tom of the tin. 



On the 18th the pupae cast the caterpillar-skin, and 

 the next day they had become brown, with darker 

 wing-cases. They were about an inch long, or a trifle 

 longer, and rather slender, with no raised tongue-case. 



We put all the pup^e in a box with glass set in the 

 lid, giving them chojiped sphagnum for bedding, and 

 devoted ourselves to crawlers who were feeding vora- 

 ciously, as is the habit of caterpillars. We did not 

 think of their emerging soon, but after some years of 

 work with crawlers one seems to acquire an instinct
