Isopteran sp.
Larvae are shiny brown or black in colour on top with paler under parts. They have elongated and cylindrical bodies that are somewhat flattened towards the head. They have two prominent upturned spines on the end of the last body segment. Fully grown larvae only reach 10 mm in length and about 1.5 mm in width. Adult beetles are brown or dark brown and grow to approximately 8 mm long. Larvae attack canola, particularly on fine textured soils.
