420 Insect Pests. 



raspberry and peach. The larva is found in September on the leaves. 

 It is reddish-grey mottled with brown, with a prominence on the 

 back of the third segment, and a smaller one on the sixth to tenth 

 segments. The moth occurs in June and July. 



The Dot Moth (Mamcstra persicarice) frequently may be found 

 on the lower leaves in caterpillar stage from July to October. 



The Fan Foot Moth (Zanclognatha tarsipenncdis}. The chief food 

 plant of the caterpillar is the raspberry, upon which it frequently 

 occurs in small numbers. The larva is dull grey, with black tri- 

 angular-shaped marks along the back, and the hind segment has four 

 while spots. It is found in September and October, and mostly feeds 

 amongst dried leaves. The pupa is formed in a cocoon amongst 

 leaves on the canes. The moth lias the fore wings brown with three 

 dark transverse lines, the basal one curved, the second waved and 

 broken, the third nearly straight, and there is also a small crescent- 

 shaped spot between lines one and two ; the hind wings are paler 

 basally and dusky towards the margin. Length of expanded wings 

 about 1 inch. Found in June and July. 



Melanthia albicillata in its larval stage feeds on raspberry and 

 bramble ; it is green, with triangular-shaped spots on the back of the 

 fourth to tenth segments and white lateral lines ; it is found in the 

 autumn and does no harm at all. 



Occasionally the larva of the Grizzled Skipper Butterfly (Si/rich- 

 thus mcdvcc, Linn.) occurs on the raspberry; it is green or brown, 

 with dark dorsal line, two white lines on the back, and one on each 

 side. It is found in April and May, but never occurs in sufficient 

 numbers to do any harm. 



THE RASPBERRY BEETLE. 



(Bijturus tomcntosus. Fabr.) 



There is no insect enemy so serious to raspberries as the Easp- 

 berry Beetle (Byturus tomentosus). It has, as one might imagine, 

 attacked loganberries also, and to such a serious extent as to threaten 

 their cultivation. "As many as six larvae have been found in one 

 loganberry. It has been known for a great many years, not only to 

 gardeners and fruit-growers, but also to the general public on account 

 of the larva the so-called Easpberry Maggot being so often found 

 in the fruit at table, especially when the fruit is picked on the strig. 

 Gardeners know it by the popular name of the " Easpberry Bug." 



Kirby and Spence, in 1827, wrote of this beetle, that " the foot
