many quite distinct blackish spots, regularly arranged and each bearing a 

 short hair. In figure 132 is represented an ajiple-worm only a few days 

 old, much enlarged, upon which these spots were very distinct. 



The Jiist meal of the Utile apple-tvorm. — \\'e have seen some of the 

 newly-hatched catcrpilhirs eating their first mea!. After emerging from 

 the egg those we saw wandered al^otit on tlie surface of the apple until 

 they found some angular place like the point where the calyx lobes 

 join the skin of the fruit, or near the stem, or in an old curculio scar, 



or where a leaf or another apple touched 

 the one upon which the worm hatched; often 

 they simply crowded in between two of the 

 calyx lobes and got their first meal within 

 the little cavity at the blossom-end. In 

 short, our observations agree with those of 

 Koebele and Washburn that the young 

 caterpillar enters the fruit somewhere else 

 than at the point where the egg is laid. 



When a suitable place was found, the worm 

 often tunneled its way through the skin and 

 went directly toward the core. Where a leaf 

 or another apple touched, the worm sometimes 

 ate away the skin for a space about as large 

 as a pin's head before burrowing in ; in this 

 case the entrance-hole was closed with a net- 

 work of silken threads in which bits of apple 

 were intermingled. In one instance a worm 

 at' little holes through the skin near the stem 

 in three or four places before it finally began 

 its journey toward the core ; other writers have 

 noted this same habit of the young worms in 

 first entering a fruit. Thus the young cater- 

 pillar may get its first meal at almost any place 

 on the apple, but usually this meal, or any subsequent meal for that 

 matter, includes only a very small portion of the outer surface of the 

 fruit. As has long been nf)ted by writers, most of the young worms 

 enter the fruit in the spring or early sunnner at the blossom-end. 

 They either crawl betwee'n the calyx lobes or tunnel into the calyx 

 cavity at the point where the lobes join the surface of the fruit. Thus 

 more often the young apple-worm takes its first meal out of sight in the 

 calyx cavity and is protected by the tightly closed calyx lobes.
