This bug is in the Shield-backed bug family. Shield-backed bugs are plant suckers.  They can be distinguished from other shield bugs by their scutellum completely covered the whole abdomen and wings. This is why sometimes they are miss-recognized as beetle. They are easily distinguished from beetles by having sucking mouthparts and the shield on the back is continuous, not the divided wings cover with separation at the middle.

Images thanks to Tracey Steele, Sydney 
On mid summer Dec 2008, Tracey in Sydney sent us the above photos and concerned about so many of those bugs on exposed roots and trunk of tree in her backyard. We know that for some insects, includes some shield bugs, females use Pheromone to attract males. Sometimes a number of males detect the smell of females and gather together around them. We never saw so many Metallic Jewel Bugs in one place and do not know why they were there. Please advise if you know the answer.
