Adults are 8 mm long, are greyish-brown with a V-shaped pale mark near the middle of the back and have a prominent snout... Larvae and adults chew sections out of the leaves of seedlings, usually in the evening and night... Eggs laid in the surface litter of the soil in autumn hatch into larvae that feed during the night on developing plants and shelter in the soil during the day...

Green vegetable bugs (GVB) and brown bean bugs (BBB) are equally damaging to pulse crops but green vegetable bugs (GVB) are considered a more important pest due to their abundance, widespread distribution and rate of reproduction... The damage potential of other pod sucking pests is not as great as GVB but they can cause severe damage when present in large numbers... Using the example above - if you find that the three GVB and one RBSB are 2nd instars instead of adults and the two BSB are 4th instars - an additional calculation is required to convert these instars into adult equivalents...

Preparation of arthropods for morphological identi cation often damages or destroys DNA within the specimen... DNA extraction methods often destroy the external physical characteristics essential for morphological identi cation... Methods used to prepare arthropod samples for morphological identi cation often prevent the analysis of DNA from the specimen, while the column-based DNA extraction methods most frequently used on arthropods require maceration of the sample, destroying the morphological characteristics required for identi cation...

Rutherglen bug ( Nysius vinitor ) and grey cluster bug ( Nysius clevelandensis ) are native species that can migrate into crops in very large numbers in favourable seasons... Rutherglen bug is a pest of many crops across Australia, while the grey cluster bug is only a pest in Queensland and northern New South Wales... Populations of Rutherglen bug (RGB) in cropping areas will breed on weeds, moving to available crops or weeds when hosts die off...
