Thanks Tim - do you know what plant the aphids are on - I am a bit worried that it may be Black Citrus aphid, Toxoptera citricida, a pest of citrus for which there are no electronic records from the ACT. However the plant does not look like a Rutaceae which is its host family.

@MichaelMulvaney I don't know the plant Michael, but the GPS coordinates are accurate if that helps with the identification. I will try and get back to the Gardens today and if I can get you the details then I'll message you directly. Tim

@MichaelMulvaney Hi Michael. I've just checked the plant at ANBG where the aphids were sighted, and they are still in place as well as on an adjacent plant. The main plant on the side of a path has the following ID: Medicosma cunninghamii. B 9702734.3 112. Hope this helps. Tim

Bugger Medicosma is a member of the Rutaceae I will make a name suggestion and alert biosecurity @ACTBioSecurity @HelenCross
@KimPullen can you please give a second opinion re ID

It does look like T. citricida as illustrated in ALA, but I don't feel qualified to confirm it as that species.
ALA has an old (1960) record of Toxoptera citricida in Canberra, see:

Thanks Kim I did see that record but was confused as to whether it was a specimen provided by CSIRO Black Mountain or a specimen collected at Black Mountain - is there any way of knowing for sure?
25 Mar 2025
The ALA occurrence record gives Black Mountain as the Locality (i.e. place where the specimen was collected, as opposed to the place where it was subsequently lodged), and 'yellow tray trap' under Occurrence remarks. These traps are simply a shallow tray (white or sometimes coloured) filled with water and a small amount of detergent to break the surface tension. Insects may fall into it, or be attracted to it, and be trapped. They can be productive for small, delicate aerial insects such as aphids and micro-wasps.

Thanks Kim - Given long term presence in area may not be such a concern but will leave to @ACTBioSecurity to determine
