THE RASPBERRY MOTH. 



{Lampronia rahicJIa. ])jerk.) 



The larva? of this small moth frequently cause much havoc in 

 raspberry" plantations, being most destructive to the canes. Many 

 gardens and plantations are said to be quite free from this pest, but 

 frequently a few may be found if careful search is made, and these 

 may, under favourable conditions, increase rapidly so that in a year 

 or two a plantation may be seriously threatened. Many patches of 

 raspberries are annually attacked, and in some years the crop has 

 been entirely lost. 



The small caterpillars of this moth are usually called the Easp- 

 berry Stem-bud Caterpillar or lied Easpberry (irul). These larvae 

 feed on the pith inside the terminal shoots, which 

 flag and then die away ; it will also be noticed that 

 ■^l^nr the base of the buds has been eaten away to such 



^^- an extent that neither foliage nor blossom appears, 



the shoots dying gradually. In most cases a dis- 

 tinct hole may be seen at the bases of the buds. 



So far as I know all varieties of raspberries are 

 attacked, and they have been found on the native 

 blackberry ; very probably therefore they will attack 

 the cultivated blackberry and loganberry. This 

 f^'" ■''•''• raspberry pest occurs in Kent, Worcestershire,

(Natural Size.) Buckinghamshire. I have also seen it in Surrey. 

 There are no records of its damage in Herefoi-d- 

 shire, but probably it exists there in small numbers. 



The first and best account of this moth was given by Professor 

 Westwood (1). To this nothing of importance has since been added, 

 except by Dr. Chapman (2).
