LIFE HISTORIES OF LEAFHOPPERS OF MAINE.

Acocephalus striatus Linn. 



This is one of the species collected in abundance in the sum- 

 mer of 19 1 3 and which it was deemed desirable to follow fur- 

 ther for the purpose of getting life-history details that might 

 be a better basis for the determining of measures for control. 

 It was taken in all parts. of the state where collections were 

 made and may be considered as of general distribution but it is 

 found in greatest numbers in meadows and pastures and espe- 

 cially in timothy meadows. There appear to be no references 

 to it as an economic species in American works and so far as I 

 know no studies in this country upon its life-history or habits 

 from an economic standpoint. It has been noted in collections 

 from Canada and the New England states for many years and 

 while a well known European species there is little reason to 

 look upon it as a recent introduction. 



Fig. 4. Acocephalus striatus. a, young nymph 1st instar (?) ; b, in- 

 termediate nymph; c, nymph of last instar. All figures enlarged, natural 

 size shown in length lines at left of each figure. (Original). 



It has been found associated with a number of different plants 

 but the nymphs have been taken especially in grassland usually 

 where there is an abundance of timothy and if there is any 

 very close restriction in food plant this grass is probably its 

 preference.
