prematurely and fall. The grub, when full-grown, passes into the 

 ground and there pupates, the beetle issuing in the fall. The beetle 

 has a peculiar habit of dropping from the tree when distui'bed. 



The quince curculio {Conotraclielus eratBegi Walsh.) is a very similar 

 insect to the plum curculio. It is the cause of knotty or wormy 

 quinces. The weevil lays her eggs in little pits of the quince eaten by 

 the parent for that purpose. The grubs feed in the quince till the 

 early fall, when they leave it and burrow beneath the ground. Here 

 they pass the winter, pupating in early spring. 



The pear midge {Diplosis pyrivora Riley) is a tiny, two- winged fly 

 much like the Hessian fly, that appears in the spring and lays its eggs 

 in young pears. The larvae feed near the core, causing the fruit to 

 shrivel and drop. When full-fed they leave the fruit and pupate 

 about an inch or so beneath the surface of the ground. The winter is 

 passed in this condition, and the flies emerge the following spring.
