CARE OF CATERPILLARS AND MOTHS 39 



In order to know the lives of the crawlers, exact 

 notes must be kept, and nothing trusted to memory. 

 The box of eggs should be numbered to correspond 

 with a page in the note-book. On this page should 

 be written the date when the eggs were laid, a descrip- 

 tion of the eggs and whether they were laid singly, in 

 rows, in a mat, or encircling a stem; the date of 

 hatching ; whether or not the larv» ate the shells ; any 

 other habits observed; and a full description of the 

 young caterpillars. The boxes containing the cater- 

 pillars, as they are divided after removal from the 

 egg-box, should be given the same number, and the 

 note-book page should have the name as well if it is 

 known. 



The record of the caterpillars' life should give the 

 food-plant chosen, the dates of molts, full descriptions 

 of the larvae after each molt, habits, degree of voracity, 

 and any other characteristics observed. It should be 

 noted when the caterpillars stopped eating before 

 pupation, when the spinning or burrowing began, and 

 when the pupa cast the larva- skin, and the pupa 

 should be full}^ described and then given the same 

 number as the larva. 



Where the kinds of pupae can be kept in separate 

 boxes, each box can be numbered like the larva-tins 

 of the species, but where several species must be kept 

 in one box the box should be numbered or lettered, 

 and a list of the contents of " Box 1 " or " Box A " en- 

 tered in a note-book. In this case care must be taken 

 not to put into the same box pupae of species so similar 

 as to make any doubt as to which moth emerges from 

 which pupa or cocoon. For instance, if we had two
