RASPBERRY. 



Raspberry Stem-bud Caterpillar. Lampronia rubiella, Bjerk. 



Lampronia rubiella.— Moth, magnified, and with lines showing natural size ; 

 caterpillars, natural size, and somewhat magnified, from life ; caterpillar and 

 chrysalis, greatly magnified, after Prof. J. 0. Westwood. 



At the end of August of the past season I was favoured by Mr. 

 Alfred Gant, of the Yorkshire College, Leeds, with iuformation of the 

 Raspberry Stem-bud Caterpillar of Lampronia rabieUa having been 

 causing serious damage in the neighbourhood of Leeds. 



The attack is not often mentioned, but sometimes is reported from 

 special localities as causing a great deal of mischief. The first notice 

 sent me of its presence was on May 2nd, 1883, when the late Mr. 

 Jenuer Weir, F.E.S., sent me a description of the method of its attack 

 on Raspberries in his garden at Chirbury, Beckenham, and also his 

 identification of the caterpillar as that of L. rubiella, which was a 

 valuable contribution, as coming from such a well-known entomologist. 

 In 1891 notes were sent of mischief caused by the caterpillars at 

 various widely- separated localities in England and Scotland ; and in 

 1899 mention was made of the attack being present to some slight 

 degree at two English localities, and of it being a serious trouble to 

 Raspberry growers in the district of Carluke, Co. Lanark, N.B. 



The following report, sent on August 31st by Mr. Alfred Gant, of 

 the Yorkshire College, Leeds, shows that in the past season it iias 

 appeared in the Leeds neighbourhood to a destructive extent : — 



" I should like to bring to your notice that this year there has been 

 a very serious attack of the Raspberry Stem-bud Caterpillar ( Lampronia 

 rubiella) in Garforth and its neighbourhood close by Leeds. A good 

 many Raspberries are grown in this district for the Leeds market, and 

 an attack of this description entails great loss upon the growers.
