White flower cricket 



Oecanthus niveus DeGeer 

 This delicate, pale greenish or white insect is one of our common species from the 

 middle of August till the latter part of September, when it occurs on various plants, shrubs 



and trees. 



This flower cricket is about ^ inch in length and may be recognized 

 by its pale color and the usually two nearly circular, black spots on the 

 basal two segments of the antennae.

 habit, and though found on various plants during the daytime, it 

 is usually comparatively motionless, becoming more active on the 

 approach of night. It is at this time, according to Miss Murt-

 aphids were supplied, none would be found in the jar the 

 next morning. 



It is interesting in this connection to refer to the observation of an 

 Indiana nurseryman, who is reported by Professor Webster, substantially as 

 follows : This gentleman experienced much trouble from plant lice till 

 after he planted raspberries in his young orchard, after which his troubles
