AN ENTOMOLOGICAL CALENDAR.

In July your lawn may be dying in spots on account of the 

 work of the White Grub. Plenty of water will sometimes 

 cause the grass to out-grow their ravages. The robins will 

 help you by eating them. 



Note whether your wheat, barley or rye is "crinkling 

 down" owing to the presence of Hessian Fly or Chinch Bugs. 

 If the "flax seed" of Hessian Fly is present in abundance, 

 make a mental note to turn under the stubble without fail in 

 the fall. 



Do not let plant lice get the better of you, as they will in 

 roses, golden glow, buckthorn and plum and apple trees, if not 

 vigorously treated. 



SEPTEMBER ANQ OCTOBER. 



Wormy apples should not be stored for any length of time 

 in fruit cellar, barn or shed, for the Codling ]\Ioth larvae 

 ("apple w^orms") will find secure retreats in such places, and 

 emerge as moths in the spring. 



If you have reason to suspect the presence of grasshopper 

 eggs in large numbers in any of your fields, plow as late as 

 possible in the fall. This prevents the young hopper from 

 emerging in the spring. 



NOVEMBER AND DECEMBER. 



Clean up fallen limbs, rubbish and everything which offers 

 secure retreats for injurious insects during the winter season. 



Pruning limbs of fruit trees in winter will remove with the 

 cuttings many lice eggs, and frequently hibernating insects as 

 well. ' ---,€-■.
