Epsilon chartergiforme (syn. Pseudepipona chartergiformis)
I spotted this small wasp which had distinctive black and yellow bands on the abdomen (gaster), and yellow spots on the thorax, of which I particularly like the "cranky face" marking. It was also smaller than other wasps and hornets I've seen in the area. The "black mud-nesting wasp" looks very similar, but I can't say promising simply because this species grows up to 20 mm long, whereas my spotting was only about 10-12 mm long.... http://www.brisbaneinsects.com/brisbane_... and.... https://www.brisbaneinsects.com/brisbane... Both are Paralastor sp. wasps. Another spotting that looks similar, but it's an unknown species.... https://www.ozanimals.com/Insect/Paper-W... Paper or potter, native or not, I just don't know yet. And they're not the best photos; it was a rescue mission, not a photo shoot. NB: My 900th spotting on PN. (2.488)
Rescued from inside an office at the Metroplex on Gateway estate, Murarrie, Brisbane.
CUT TO THE CHASE! I've just sent a message to the Australian Museum in Sydney, asking for their assistance to ID this spotting. 11/06/2020: The response.... This wasp is the species Epsilon chartergiforme, which is one of the Resin Mason Wasps. In checking with an entomologist they said that “species of Paralastor, , that might be mistaken for Epsilon. The nest would, of course, clinch the identification or close examination of a specimen.” PS: Now that I know what type of wasp this is, here's a fine example of why it's called a "resin mason wasp".... https://www.flickr.com/photos/58356728@N...
