Cotton Harlequin Bug

The Cotton Harlequin Bug is a member of the Jewel bug family (Scutelleridae) named for their bright metallic colouration. The males and females are different colours, with the females mostly orange and the males mostly blue-red.


The Cotton Harlequin Bug feeds on many species belonging to the hibiscus plant family (Malvaceae), including ornamental hibiscus species and cotton. It feeds mostly on young shoots, piercing the stems and sucking the sugar-rich juices intended for shoot growth. They are sometimes a minor pest of cotton and have been known to cause the introduction of a fungus, which rots the cotton boll. In gardens, they cause flower buds to drop prematurely.

This species is common during summer in Sydney gardens and among ornamental trees in parks. The females tend their eggs to ward off the hungry eyes of wasp parasites.
