Fig. 8. The Strawberry Crown-borer. (Tyloderma fragarie, Riley) 
beetle, side view: ¢. adult. dorsal view; d. pupa, from beneath. 
[A thick footless white grub, about a fifth of an inch in length, with a browne yel- 
low head, excavating the crowns of the strawberry during the summer and fall. 
This insect is one of the principal obstacles to successful straw- 
berry culture in those localities where it has gained a footing, and 
anything throwing light upon possible methods of controlling its 
injuries cannot fail to have a very considerable value to horticul- 
turists, even in those regions hitherto exempt from its attacks. Its 
characters and life history should be perfectly understood in order 
that all suitable precautions may be taken against invasion by it, 
and that its first appearances may be recognized if unfortunately 
it should be transported beyond its present range. Although it has 
hitherto done but little harm in the northern or central part of 
this State, the beetle certainly occurs as far northward as Minnes- 
ota, and there is no security that it may not become injurious 
wherever introduced. 
This insect has been known as one of the worst enemies of the 
strawberry for more than fifteen years, but it has never yet been 
treated in our State reports, and, indeed, its life history is but ust 
completed,
