colored stripe running the entire length of the body just below 

 the spiracles, the body striped the entire length both above 

 and below with fine longitudinal whitish lines. The cater- 

 pillars become mature about the middle of June. and transform 

 to pupae just below the surface of the sand. The sulfur yellow 

 moths begin to appear in a few days and continue on the wing 

 until the middle of July. The second brood of caterpillars 

 becomes mature in late July and early August. 



The measures for the control of this species are the same as 

 those recommended above.

The Cranberry Gall-fly 

 Cecidomyia oxycoccana Johnson 



The terminal buds of the cranberry are sometimes deformed 

 into a gall-like growth by the presence of several yellowish or 

 orange-red maggots about one sixteenth inch in length. In- 

 fested buds are killed and when the injury occurs late in the 

 season the formation of fruit buds for the following year may 

 be prevented. The larva becomes full-grown in about ten 

 days, spins a delicate cocoon inside the deformed bud and there 

 transforms to a pupa. The adults emerge a few days later ; 

 they are delicate, two-winged, mosquito-like flies, having an 

 expanse of less than an eighth of an inch. The females have 

 the abdomen deep red and the sides of the thorax yellowish ; 

 the male is a uniform gray. The female is provided with an 

 extensile ovipositor at the tip of the abdomen by means of 

 which she is able to place her minute white eggs in the center 

 of a developing bud. There are several broods annually. 

 The insect also infests loose-strife and certain heaths. 



The cranberry gall-fly has never been a serious pest. It
