ORCHARD LIFE.

i. Search for the eggs in any of the fruits named 

 above. Their presence can be easily determined by 

 a peculiar mark made by the female when laying her 

 eggs. A hole is made through the skin of the fruit, 

 and into this hole the egg is put. The insect then 

 makes a crescent-shaped incision partly surrounding 

 the one containing the egg. 



2. If the dot and crescent mark is found on the 

 fruit, search should be made for the adult insects. 

 These are most easily found early in the season, and 

 can be readily obtained by spreading a cloth under 

 an infested tree and jarring the tree. The adults 

 will drop to the ground feigning death. Specimens 

 should be pinned for your collection. 



The adult is a beetle. It is about one fifth of an 

 inch in length, and is dark brown spotted with black, 

 yellow, and white. The wing-covers are rough, and 

 the head is prolonged into a snout, which is bent 

 back under the prothorax when at rest. 



3. Preserve in alcohol specimens of fruit showing 

 the dot and crescent mark. Cherries will be most 

 available for this on account of their small size. Pre- 

 serve also specimens of the larvae. 



4. Describe the way in which the larvae injure the 

 fruit. 



5. Place infested fruit in a breeding cage on a 

 layer of earth ; determine method of passing the 

 pupa state ; preserve specimens of pupas ; and breed 

 the adult insect, so as to determine whether the in- 

 sects that you collected by jarring are really the 

 adult of this species. 



6. Write an account of the habits and appearance 

 of this insect.
