94 FRUIT TREES AND THEIR ENEMIES 



Raspberry Stcm-Biid Caterpillar {Lainpronia rubi- 

 ella). — This attacks the leaf-buds and shoots, not the 

 blossoms ; the eggs, however, are laid by the moth in 

 the blossoms, and the caterpillars remain near the 

 fruit till this is ripe ; they then let themselves down 

 to the ground and spin their cocoons, in which they 

 pass the winter, emerging from them in the following

 caterpillar is red, and about a quarter of an inch in 

 length. 



Remedies, — A common plan is to smear the canes 

 in early spring with grease. Spraying with weak 

 emulsion before the buds expand may be suggested.

 of ground beetles often do much damage to straw-

 soil during the day, and feed at night. 



Remedy. — Sink cheap pudding dishes, or similar 

 vessels, into the ground, so as to be flush with the 

 surface ; put into them pieces of lights and sugar- 

 water. The beetles come to feed on the lights, and 

 cannot get out of the basins. 



Cockchafer {Melolontha vulgaris^. — The beetle is 

 brown, and over an inch in length. It is active 

 during May and June, and does much damage to 

 the foliage of various trees. It lays its eggs 6 to 8 

 inches below the surface of the ground and the
