This species is known to the cranberry grower as the tip worm. 

 The first sign of its presence, according to Doctor Smith, is the 

 unusual prominence of certain terminal buds accompanied by a cessa- 

 tion in the growth of the leaves. An examination discloses the 

 yellowish Cecidomyiid larvae within the affected bud. The tip 

 usually though not always dies. This midge causes considerable 

 injury to cranberry beds.
