Hi Michael Batley Thanks for ID'ing this one. We have a few other unidentified bees. Could you please do us a favour and look at the gallery of unidentified insects, which is at: http://canberra.naturemapr.org/Community/Unidentified/4 Sometimes people put in sightings of bees without knowing whether they are a bee or not, in which case you don't get a notifying email. Something for you to keep in mind. Thank you
