STRAWBERRY WSECTS 371 



strawberry plants is sometimes very severe ; the beetles appear 

 in immense numbers and completely riddle the leaves. 



The beetles deposit their eggs on leaves of the evening prim- 

 rose and related plants. The larvae feed on the leaves and seed- 

 pods, going into the ground to transform. Then^ is only one 

 brood a year in the North and two or three in the South. 



Treatment. 



The beetles may be driven away by thorough applications 



of Bordeaux mixture. By adding arsenate of lead, 4 to 8 



pounds in 100 gallons, it is possible to kill a few of the beetles, 



but probably not enough to pay for the trouble. As the only 



known food-plants of the larvae are the evening primrose and 



its allies, such weeds should not ])e tolerated in the vicinity of 



strawberry beds.

The Imbricated Snout-beetle 

 Epiccerus imhricatus Say 



Strawberry plants are sometimes defoliated by this greenish- 

 brown snout-beetle f to J inch in length. The wing-covers are 

 crossed by two irregular light bands, more distinct in the males. 

 The greater part of the insect is clothed with small appressed 

 scales which are imbricated or overlap, like the scales of a fish, 

 hence the common name. The insect is found east of the Rocky 

 Mountains, except in the extreme North and South. It is 

 a general feeder in the adult stage, attacking, among others, 

 apple, peach, pear, cherry, raspberry, gooseberry, onions, beets 

 and cabbage, in addition to a large variety of wild plants. 



In confinement the female deposits her smooth elongate, dull 

 yellow eggs in clusters on a leaf and then glues another leaf or 

 a portion of the same leaf over them. The larva is a root 

 feeder, but its natural food-plant is unknown.
