Nysius vinitor
Rutherglen bugs are a common native insect that attack a wide range of crops and weeds including canola, lucerne, wheat, sunflowers, safflowers, linseed and sorghum. Adults are 4 mm long and grey-brown in colour with clear wings folded flat on their back. They are narrow-bodied with prominent dark eyes, and they are highly mobile. Nymphs are wingless and have a dark red, pear-shaped body. Rutherglen bugs are typically a problem in spring, but can also be a sporadic pest of seedling crops in autumn. They are regarded as opportunistic and can reach plague proportions in some seasons.
