STRAWBERRY. 87 



Another leaf enemy of the Strawberry is known as the 

 "Strawberry Leaf -roller" (Anchylopera frayarice, Walsh 

 and Riley), of which figure 28, a, gives the larva of nat- 

 ural size, and b, the moth, enlarged. This insect, like 

 the last, appears to be more abundant at the West than 

 eastward. Still I have frequently found it on the plants 

 in my garden, and I presume it is not uncommon in 

 strawberry plantations throughout the country, but only 

 noticed when so abundant as to strip the plants of their 

 leaves. In feeding, it folds up 

 the leaves, drawing the edges to- 

 gether with silken threads, and 

 then eats out the more tender or 

 pulpy parts. Prof. Riley ^flfp 

 states that there are two a 

 broods of this insect dur- a ' Larva ; & ' Moth '

of the first brood passing through their transformation on 

 the leaves, the moths appearing about the first of July. 

 The female moths deposit their eggs on the leaves, where 

 they soon hatch, and the worms commence their work ; 

 but those of the second brood, when coming to maturity 

 late in the fall, descend into the ground, change to pupae, 

 and remain in this state until the following spring. 

 Owing to the habit these worms have of rolling them- 

 selves up in the leaves, they are somewhat protected from 

 destruction by any dry or liquid application that may be 

 made to the plants for the purpose. Sweeping the leaves 

 with a broom will disturb and destroy a few of the worms, 

 but the most rapid method of destruction is burning oft 

 the leaves after the fruit is gathered, or passing a heavy 

 roller over the plants in time to destroy the second or late 

 brood in autumn. 



The Strawberry Crown Borer (Tyloderma fr agarics, 

 Riley), is another pest of the Strawberry, more or less 

 abundant in the Western States and Canada, but I have
