The Strawberry Crown-miner. 



Anarsia lineatella (?) 

 This is a small, reddish caterpillar (Fig. 35) that 

 bores the strawberry crown, making irregular chan- 

 nels through it in all directions. 

 It becomes fully grown early in 

 summer, and changes to the chry- 

 salis state, to emerge two or three 

 weeks later as a small, dark-gray 

 moth. Eggs are deposited by this 

 moth upon the crown of the plant, 

 and soon hatch into minute larva? Fig. 35. The strawberry

that bore the crown again, becom- 

 ing partially grown before winter, and hibernating 

 within their burrows. This is the life history of the 

 species in Canada ; probably farther, south there may 

 be two broods a year. 



Remedies. — No successful remedy for this insect 

 is known. Badly infested fields would probably 

 have to be plowed up, and this should be done 

 preferably in the fall or early spring. 



The Strawberry Crown-borer. 



Tyloderma fragarise. 



This insect has been known for many years as one 

 of the most destructive enemies of the strawberry in 

 the great small-fruit fields of the Mississippi Valley.
