14. Preserve some caterpillars in alcohol, and 

 put them in your collection near the cluster of 

 eggs. 



15. Observe and describe the making of cocoons. 

 Note the date when the cocoons are made. 



16. After you are familiar with the appearance of 

 the cocoons, look for them out of doors, and find out 

 where they are made. 



17. Open a cocoon a few days after it is made, 

 and describe the pupa. 



18. Preserve a pupa in alcohol, and put it next to 

 the larvae in your collection. 



19. Watch for the appearance of the adult moths, 

 and thus determine the duration of the pupa state. 



20. Preserve specimens of the cocoons and moths. 

 First kill the moths by putting them in the killing 

 bottle, then pin and spread them. When dry, take 

 them from the spreading board, and put them in the 

 collection with the other specimens illustrating the 

 transformations of the species. Try to get both sexes 

 of the moth ; the females are larger than the males, 

 and have narrower antenna3. 



21. Make a picture of the moth. 



22. Write an account of the life history of this 

 insect. 



23. Arrange the specimens of the apple-tree tent- 

 caterpillar in your collection under a copy of the
