Hibiscus Harlequin Bug (Tectocoris diophthalmus) from my Hibiscus Plants - Cairns
Just the next two I wanted to add with different angles. I had a number of these sucking bugs on my hibiscuses. I have others to post too. Some are even orange. This one I took mainly while it was crawling on my hairy finger (sorry). The bigger orange one is about 15 mm but this one here is maybe 8-10 mm. The colour varies from pale orange to heavily patterned in metalic green, blue and red. The back is covered with an enlarged shield-like scutellum.
They live in Northern and Eastern Australia and in Papua-New Guinea and some Pacific islands. They suck the sap from hibiscus plants and also from a species - Hibiscus tiliaceus. They can also attack cultivated cotton. The female lays clusters of eggs around twigs, and guards them until hatching. This is probably why they kept on the branches so much on one of my bushes but I did not think to look for eggs.
