HOP. 



it is well to have a stock liorc and there examined tbrougliout 

 the ground when the plants are dressed in the spring. 



Also, as the moths frequent grassy places, and the cater- 

 pillars feed on the roots of the Burdock and of the common 

 Nettle, it would be very desirable to clear off these large weeds 

 and also patches of neglected Grass which give harbourage by 

 day to the moths.

The caterpillars of this moth injure the Hop by feeding on 

 the leaves. They are of a pale green colour, with clearer 

 spots, and a whitish line on the sides and back ; slender in 

 shape and gradually smaller towards the head, and of the size 

 figured above ; and are distinguishable by having only three 

 pairs of sucker-feet (in addition to the true feet on the rings 

 next the head), and the pair of sucker-feet at the end of the 

 tail. 



When full-fed the caterpillar draws a leaf partly together, 

 and commonly changes to the chrysalis in a light cocoon 

 which it spins within the folds. 



The moth, which appears in June and July, or earlier, is 

 rather more than an inch in the spread of the wings, and is 

 variable in colouring. In well-marked specimens the fore 

 wings are greyish brown, darker from the base to about the 

 middle, with a zigzag blackish streak across near the tip, and 

 some raised tufts of black scales about the centre ; the hinder 

 part of the wings is palest. The hinder wings are brownish. 



The moths of this genus may be generally known by the 

 snout-like appearance of the front of the head, whence they 

 take their name. — ('Illus. Brit. Entom.')
