The Cherry Leaf -beetle (Galerucella cavicollis Lee.) 

 An oval, red beetle, one fourth 

 of an inch long, with black legs 

 and antennae, feeds on the leaves 

 of cherry, plum, and peach, and

The Strawberry Leaf-beetle (Tijpophorus canelliis Fab.) 

 A chunky, dark beetle, one eighth of an inch long, with four obhque, 

 black patches on its wings, occasionally appears in large numbers in 



strawberry fields early in 

 the season, and riddles 

 the leaves. The larvae 

 or grubs which follow 

 shortly are small and 

 thick bodied, and feed on 

 the roots of the plants. 

 The beetles hibernate as 

 adults. 



Prompt spraying with 

 Paris green or arsenate 

 of lead will check the 

 beetles.
