Hi,
My backyard has heaps of these bugs. They tend to hide behind bark. I have never seen them fly. I always have a seed bell hanging from a tree to attract mostly rainbow lorrikeets. The bugs swarm over the bell when the birds have gone. What are they and most importantly are they a danger to plant and tree life ?

Unknown Australian True Bug

Harlequin Bug from Australia

Dear Henry,
We didn’t have any luck identifying your True Bug in the order Hemiptera on the Brisbane Insect website. The behavior you describe is similar to North American Boxelder Bugs in the family Rhopalidae, the Scentless Plant Bugs. Other good candidates are the family Lygaeidae, the Seed Bugs or Largidae, the Bordered Plant Bugs. Hopefully one of our readers will write in with an identification.

Daniel:
I believe this beautiful true bug is in the genus Dindymus (Pyrrhocoridae), probably D. versicolour . The common name in Australia is Harlequin Bug (sometimes Fire Bug), although that name also seems to be applied to several related species. They are considered a plant pest, particularly on fruit trees. As the species name suggests, they show considerable variation on color. Another possibility might be D. ventralis. Regards.

Thanks Karl,
Seems we overlooked the Fire Bug on the Brisbane Insect Website because of the coloration not matching the photo we received.
