Tiny bees, only a few mm long, swarming between flowers of a garden-planted Babingtonia.
When disturbed the swarm flew off but returned to the same position at the end of the branch.
Identified as Hylaeus (Heterapoides) bacillarius by BJ via Bowerbird.
"Heteropsilopus (the dm-cu cross vein is sinuous) and I think this is the common H. ingenuus (Erichson) because you can see the enlarged modified tarsus II sticking outside the wings on both sides." Ken Walker
This black robber fly was about 15 mm long. The thorax was flat along the midline and symmetrically lumpy on either side. Eyes were large and facing upwards. Stiff white bristles seen between the eyes and on the face. Legs also had stiff white setae. Wings were dark and folded over the abdomen which had white spots on the lateral aspects of some of the tergites.
Spotted flying around dried logs ( Langwarrin Flora & Fauna Reserve).
