Agonoscelis rutila
Family: Pentatomidae (stink bugs)
Order: Hemiptera
Although an Australian native insect, this bug usually feeds on the sap of introduced Horehound plants, or others in the mint family (Lamiaceae) sometimes causing wilting. Although they prefer Lamiaceae, they are known to aggregate on a variety of other plants. In this case I think it is a different plant family; Billy Goat Weed, Ageratum sp. in the family Asteraceae. They also feed on various seeds including the Horehound.
The species is quite communal and aggregates with others of the species on the target plants. It has the capability to control the spread of the Horehound plant, which is considered to be a weed. However the Bug is the target of parasitoid wasps including the introduced egg parasitoid, Trissolcus basalis. Ironically this wasp was introduced to Australia to control another bug, the Green Vegetable Bug but has turned to preying on the native Horehound bug (and 25 other native bugs as well). So it seems that an introduced wasp is preventing a native bug from controlling an introduced weed!
This was a focus stacked image from 46 individual handheld shots using a 90mm Sony lens and a Sony A7R with flash. The stacking was done using Boltnev and Kacher's "Focus Stacker" app.

Weiß jemand, was für eine Wanze das ist?
Does anyone know what kind of true bug this is?
out front in God's garden. "Seek" says it's a Carpenter Bee. Not the best shot and only got two ... but it's a beautiful pollinator!
Best viewed large,
Lady bug feasting on red aphids, my cup plant has turned red, never seen this before. Looks like they begin life black and then change to red, thought they were ants but looking closer are actually aphids. Rain will wash them off maybe, if it ever gets here, long hot drought conditions continue.
Pittosporum Bug (Pseudapines geminata) nymph
A different type of Pittosporum Bug, the first I have seen. It was on a leaf of our Pittosporum tree. Hopefully I will get to see an adult sometime, they are good looking bugs.
Last summer the wrens had a good year.

Pyrrhocoridae is a family of insects with more than 300 species world-wide. Many are red coloured and are known as red bugs and some species are called cotton stainers because their feeding activities leave an indelible yellow-brownish stain on cotton crops. A common species in parts of Europe is the firebug, and its genus name Pyrrhocoris and the family name are derived from the Greek roots for f... Wikipedia
Small "true" bug, about 4-5mm
The tip of the forewing of Heteroptera is fairly thick (~1.2 microns), thus there is no color iridescence visible (brown curve). The base is even thicker and leathary. This is the origin of the name "hemiptera" which means "half-winged". The newer name Heteroptera means also "mixed-wings". This leads to the typical "X" structure of the closed wings in dorsal view, which is an easy means to identify "true" bugs.
Hind wings in contrast, are much thinner (~0.2 microns here), which leads to a brillant blue-violett if illuminated coaxially.

If you ever wonder where the old VW Bugs went to, you can find many of them in Mexico. We found this one in San Miguel de Allende recently. This is processed in the spirit of Sliders Sunday. HSS!
The quote from the animation Bug's Life by the Grasshopper "You let one ant stand up to us, then they all might stand up! Those puny little ants out number us a hundred to one and if they ever figure that out there goes our way of life! It's not about food, it's about keeping those ants in line."
