The "Suck Fly." In spite of its name, this insect (Dicyphus 

 minimus Uhl.) (Fig. 231) is a true bug, and has in recent years 

 become quite troublesome to tobacco growers.

Life History. The insects are found on both sides of the leaves, 

 affecting the under side of the nymph or imperfect stage. The 

 eggs are said, by Quaintance, to be deposited singly within the 

 tissue of the leaf and they require about four days for hatching. 

 The entire cycle of one generation is completed in about fifteen 

 days.
