The larv;c of tliis small iiiotli frequently cause mucli havoc in raspberry plantations, being most destructive to the canes. Many crardeus and plantations are said to be quite free from this pest, but frequently a few may lie found if careful search is made, and these may, under favourable conditions, increase rapidly so that in a year or two a plantation may lie 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 liasp- iierry Stenr-ljud Caterpillar or Red Easpberry (^Jrub. These larvje feed on the pith inside the terminal shoots, which flag and then die away; it will also lie noticed that 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 liole may lie seen at the bases of the buds. So far as I know all varieties of raspberries are attacked, and tliey have been found on the native Ijlackljerry ; very probably therefore they will attack the cultivated blacklierry and loganberry. This raspberry pest occurs in Ivent, Worcestershire, CUoucestershire, Warwickshire, Cambridgeshire and Buckingliamshire. I have also seen it in Surrey. There are no records of its danuige in Herefo'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 lieen added, except by f >r. Chapman (2).
