The males of this Leioproctus Protomorpha sp. are particularly fast and noisy fliers. The males occasionally alight to take nectar but most of their time from mid-morning to late afternoon is spent in flight.
The Leioproctus Protomorpha sp. taken on the Eucalyptus platypus, known as the Coastal Moort, were taken in mid January.
Aaaaaarrrggghhh! Idiot! Idiot! Idiot! goes the silent scream in my head…
When I first saw this big beautiful one come walking over the flowers the mind said “by the size and length of it, it’s some kind of flower wasp…” never seen a grey one before… But the gut was saying “No, there’s something different about this one…” so I snapped a couple of half hearted pics…
When I loaded the pics on to the computer where I could see clearly, I saw the tuft of fur on the butt. That’s pre-pygidial fimbriae, a specialised adaptation found in ground nesting bees that is used to brush secretions produced by the abdomen on to the inner walls of her burrow, a bit like brushing Bondcrete on to fretting mortar to stop it falling apart…
Aaaarrrggghh… a brand new bee for the albums and I only took three pics… Stupid mind, I’m never listening to it again! 😆

The difficulty of identifying is illustrated here, with the first ID of this native bee, being that of the male Ctenocolletes nicholsoni, which has now been revised to Leioproctus Protomorpha sp.
Bee probably went through difficult times, flagellar segments broken, both sides… Stenotritidae, u are right. Metasomal segments elongated, extremity presence two tiny spines. It is a male. Apical margins of metasomal terga pale towards end, last tergite brown-black. Might be: Ctenocolletes nicholsoni (Ckl.).
