Adelium brevicorne
Adult bronzed field beetles are up to 11 mm long and are shiny black in colour with a slight bronze appearance. Adults are flightless and emerge late in spring, then shelter in crop residues during summer and autumn. Larvae are dark brown with short legs and grow up to 12 mm long and 3 mm wide. They have cylindrical elongated bodies with 12 body segments and 6 legs. The last segment has 2 distinct upturned spines on the end. Larvae attack canola, particularly when sown into heavy stubble.
