Cabbage Stem Weevil
A grey weevil that mines inside brassica stems. Larvae tunnel through stems causing weakening. One of several Ceutorhynchus species affecting oilseed rape.
Did You Know?
Larval tunneling weakens plant stems to the point where they may snap in windy conditions.
Silver Birch Web-Spinning Sawfly
A flat-bodied sawfly with long filiform antennae and a broad head. Larvae roll or fold birch leaves with silk and feed within the shelters.
