Scientific name: Musgraveia sulciventris
Description
Bronze orange bug are a pest to citrus trees causing damage to new foliage, flowers and fruit. The nymphs are usually seen during the winter months on the underside of the leaf and appearing as small, green and disk shaped, and approximately 3mm. The adults are present in the warmer months and are 25 mm in diameter with and orange or orange-pinky appearance. As they age they become dark and almost black in colour. Both nymphs and adults produce foul smelling secretions that scorch and damage leaves. If you handle them it can cause staining to the skin. The combination of high temperatures and low humidity usually caused the bugs to die. During hot weather the bugs can usually be found at the base of the tree as they seek to keep cool.
