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!

Weiß jemand, was für eine Wanze das ist?
Does anyone know what kind of true bug this is?
Like assassin bugs nymphs, stilt bug nymphs molt several times as they mature. I happened to catch one in the process on this gaura stem. It looks like most of the exuvia is sitting on the stem. It would have made an interesting video, but I wouldn't have been steady enough...
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.
I was going through some of the older photos and came across these little critters. Does anyone know what they are? I know I was in the village of Little Washington where there is a really large garden and I think these were probably not a welcome addition to the garden judging by the look of the leaf below them. Happy Sabbath to all, it's a wonderful, beautiful day here today. :)

Showcasing an array of bizarre food creations, the unusual menu consists of extreme 'delicacies' such as parfaits topped with a crisp cicada, dishes containing fried bugs and insects, as well as roasted crows and crocodile.

This beautiful flower in a neighbor's yard in Santa Rosa, Sonoma County, California is drawing insects. This was taken with my iPhone 14 Pro Max on the Raw and Macro settings.
In my garden 15th April 2022
I sat in the garden and watched things happen today.

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."

Bug is pretty hard to identify in this photo but it is firmly held at the tip of the beak. I probably would not have posted this if it were not my very first hummingbird image of 2022 ... :)
