RASPBERRY. 



Kaspberry Stem-bud Caterpillar. Lampronia rubiella, Bjerk. 



Lampkonia eueiella. — 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. 



The mischief caused by this attack in its commencement 

 may be readily known from that caused by the Byturus beetle 

 and its maggot, mentioned in the foregoing paper, by reason 

 of it affecting the inside of the young leaf-huds, or shoots, 

 or inth, whilst the beetle attacks the Easpberry blossom or 

 blossom-buds. In both cases egg-laying takes place in the 

 flowers. 



The infestation was described by Prof. J. 0. Westwood as 

 long ago as 1853 in the volume of the * Gardener's Chronicle ' 

 for that year, with good illustrations accompanying, from 

 which I borrow the much magnified figures of the caterpillar 

 and chrysalis given above, and from time to time the same 

 attack has been noticed ; but I never received any special 

 report of it as markedly injurious until 1883, when I was 

 indebted to Mr. Jenner Weir, F.E.S., for observations of the 

 habits of the larvae on Easpberry shoots in his garden at 

 Chirbury, Beckenham, and also for identification of cater- 

 pillars as being those of L. rubiella. * 



Since the above date, though the attack did harm in various 

 places, the only bad outbreak of which I have had information 



* The many appellations that have been bestowed upon it, of which the list 

 is given by Prof. Westwood in his excellent paper on this insect (' Gardeners' 

 Chronicle,' 1853, p. 757), are of some interest, as showing the great difficulties 

 which variety in scientific names causes to inquirers. The moth was Tinea 

 corticella of Linnjeus ; the Swedish naturalist, Bjerkander, named it Tinea 

 rubiella; it was placed by Stephens in the genus Lampronia ; Fabricius named 

 it Alucita variella ; Duponchel gave the specific name of viultipunctella ; 

 Sodofisky that of i'7t.'c/(t'?-c?Za; and it is stated to be Glijphipteryx variella of 

 Stainton's ' Catalogue of Tii^ieidje.' — E. A. 0.
