Treatment: the grubs are easily controlled by spraying with 



poison, and, if this be done, there will be few^er beetles to fight 



in the spring. Early injury by the beetles may also be prevented 



by spraying the buds thoroughly, using one pound of poison to 



75 gallons of water, or by hand picking. 



20 Grape vine plume moth ( O x y - 

 ptilus periscelidactylus). 

 Small, greenish, hairy caterpillars 

 webbing together terminal leaves. 

 The caterpillars' w^ork is most ap- 

 parent the last of May or early June, 

 and w^hen abundant they may cause 

 considerable injury. The delicate, 

 brownish, plume moths appear about 

 the middle of June. 



Treatment: pick and destroy in- 

 fested tips. 



27 Eight spotted forester ( A 1 y p i a 

 o c t o m a c u 1 a t a ) . Reddish, 



black-ringed caterpillars about 1^ 

 inches long feeding on grape vine 

 and Virginia creeper in spring. The 



l>arent insect is a beautiful black moth marked with eight yellow 



spots on the wings and with 



handsome orange tufts on the 



forward and middle pairs of 



legs. 



Treatinent : handpicking ; 



spray with poison. 



28 White flower cricket 



( O ec a n thus n i v e u s ) . 



Scries of punctures in twigs of 



of various kinds are made by 



this insect for the reception of 



its eggs. The injury is usually 



too little to call for remedial measures, specially as the insects 



nrc predaceous and beneficial, and should therefore be protected.
