This small caterpillar feeds on the leaves and fruit of the 

 raspberry and blackberry, especially the fruit, and is more con- 

 spicuous for its unwelcome presence there than for the amount 

 of injury which it does. It is particularly troublesome because 

 it has the ability to so thoroughly disguise itself that it is diffi- 

 cult to detect. It does this by fastening to the thorny prickles 

 on its body bits of dried berry, seed, pollen, leaves and other 

 debris which, added to its habit of looping itself into a small 

 ball, renders the disguise complete. 



Confining itself principally to the ripe fruit, no practical 

 remedy seems to be available. 



THE KASPBERRY-CANE MAGGOT

This is the larva of a true fly, grayish black in color, closely 

 resembling the common house-fly, though not quite as large. 

 The larva is a slender, white, footless maggot, found burrowing 

 in the tips of raspberry canes. It is closely related to the radish 

 and onion maggot. The eggs are laid early in spring, very soon 

 after the young canes start, in the fork at the base of the tip 

 leaves. The young larva burrows into the cane near the point of 

 hatching, works its way downward in the pith a short distance,
