This group is flourishing in an area beside cycle path that is no longer (regularly) mown - a conservation bollard marks the protection zone (see top right in my group shot). This protection started in 2022 (https://canberra.naturemapr.org/sightings/4445697) and has continued fairly reliably since then. With any luck, good seed should set this year.
I went yesterday afternoon and walked and watched this population. I saw not a single insect either leaving or visiting over about 10 minutes. Possibly was not the best time as cloud ranged from light to medium but it felt warm enough.
I also found the patch yesterday at about 1 pm - surprising we did not cross paths. I photographed several Lasioglossum lanarium resting in the Goodenia flowers but nothing on the Stackhousia as usual. Plan B is to observe them at night somewhere convenient.
