FARM FRIENDS AND FARM FOES 



Flea Beetles live as miners in the leaves and stems of va- 

 rious plants. Spraying with Bordeaux mixture is one of 

 the best methods of preventing their injuries. 



Long-horn Beetles 



The so-called Long-horn Beetles (Cerambycidae) form 

 one of the most important groups of the order. The adults 



have cylindrical bodies, frequent- 

 ly of large size, with feelers or an- 

 tenna; generally as long as the 

 bodies or longer. These beetles 

 deposit their eggs upon the bark 

 or wood of a great variety of trees 

 and shrubs, and the eggs hatch 

 into footless grubs that burrow 

 into the bark or wood of the host 

 plant. Some of the most destruc- 

 tive fruit-tree pests belong to this 

 family, a notable example being 

 the Round-headed Apple-tree 

 Borer, which is often very injurious in apple orchards. 



The Locust Borer is one of the most abundant as well 

 as most beautiful of the beetles belonging to this family. 

 It is attractively cdlored, being brown or 

 black, marked and striped with lines of 

 light yellow. This beetle is very abun- 

 dant in late summer and early autumn 

 upon the flowers of goldenrod, which it 

 visits in search of pollen. The life his- 

 tory briefly summarized is this : The 

 beetles found in August or September 

 deposit their eggs one at a time in the 

 crevices of the bark of the common or ^° 6™^^"
