recent borings; c, section through an old stem

A. ruficollis Fab. Common throughout the State in June. The larva 
bores in stems of blackberry and raspberry, forming galls on some 
varieties and becoming more or less injurious. Cutting out the galls 
and burning the cuttings in winter destroys the brood. As the eggs 
are all laid by July 1st, cutting out all shoots made at that time and 
depending upon those starting after that date will secure exemption 
for the year next following.
