At this time of year the larvae commence their nightly ascents in search of juicy young buds. They seem to selectively shear away the woolen jacket in order to reach the green goodness below. In doing so, they have robbed me of a summer cane which will potentially carry three bunches of riesling berries. On a good night, they will make their way along a whole cane, stripping every bud they come across. Spur-Pruning minimises the damage.
