|The grape cane
gall-maker is a sporadic pest of grapes in the eastern United States.
This insect produces noticeable red galls on new shoot growth just
above nodes. The majority of galls are beyond the fruit clusters
and cause no serious yield loss. Canes with galls can still produce
a crop the following year.
The adult is
a dark brown snout beetle about 1/8 inch
(4 mm) long that looks like the grape
cane girdler. The legless grub is white with a brown head and
slightly larger when full grown.
