The Grape Berry Moth (Polychrosis viteana Clem.) 
Most ‘ wormy ” grapes, so often seen on vines, exhibit the charac- 
teristic work of the grape berry moth. While the berry is still green, 
a purplish spot appears on one side. If it is cut open, a small 
greenish or purplish caterpillar will be found within. 
Thisis the larva of the sec- 
ond brood. Earlier in the sea- 
son, when the grapes are in 
blossom or the berries are just 
forming, the inconspicuous first 
brood of caterpillars is on the 
vines, eating into the blossoms 
and tiny fruit, and webbing up 
the clusters. = Rar
