We found a few of these stink bugs on the flowering Phyllota phylicoides in Carbrook Wetland on Sep 2009.

The stink bug is brown in colour with olive-green thorax and greenish-brown head. The scutellum is brown with creamy white tip. The shoulder is round without spin.

The bugs were slow moving. When heavily disturbed, they walked slowly to the top of the plant, opened its wings and slowly flied to another host plant one to two meters away.

We noticed one of them was paler in colour, otherwise look the same. It walked freely and did not like just came out from last moulting. It could be the female, but not so sure.
