Hemicordulia tau Tau Emerald

Suzanne Jones Thanks Russell. Just a question though. I thought that the pterostigma of Hemicordulia australiae was black, while the pterostigma of Hemicordulia tau was brown. Is this not correct? That was why I thought it was H. tau.

Russell Best You are spot on Suzanne. I was in a rush (doctors waiting room) and I didn't even look at the pterostigma. I first look at the abdomen shape for these two species and made my decision solely based on the shapely abdomen and thin 'waist', which points to H. aus. and not H. tau. But you are spot on in that pterostigma colour is an excellent distinguishing feature and in this case points clearly to H. tau. After your comment I looked at the other differenting features and half point to H. aus.. These features are yellow spot on tail in H. tau is absent, curvy abdomen with thin 'waist' for H. aus. is there, yellow veins on leading edge of wings for H. tau are there, brown pterostigma points to H. tau. I've had a look on the web and I can find no deviation from the black pterostigma in H. aus. so I will follow it up further. It is a very interesting case!

-
Russell Best I meant to conclude that the distinguishing features score is 2:2 between the two species!

Suzanne Jones I wondered if maybe it was my photo and that the wings were making it just look as if it had a thin waist, so have added another photo of the dorsal view, taken from a very slightly different angle. Don't know if it will help or not. The wings are a bit blurry in all my photos because the insect was moving them constantly.

David Francis Well spotted. I could dig them out.

Russell Best I think bits of root come off and they regrow - not sure? Roundup doesn't work either because the ends of roots survive. There is a cocktail that works but I don't know what it is. PV might know. If not I can try chasing up alternatives.

Chris Lindorff Hi Leuba. The name has now been added. Cheers. Chris.

David Francis Was this identified from brisbaneinsects? http://www.brisbaneinsects.com/brisbane_robberflies/BlackLeggedBlackRobberFly.htm
-
-
Leuba Ridgway Yes David. If it is incorrect please let me know. Thanks.
-
-
David Francis Leuba, your observation is a perfect match to the photos on brisbaneinsects which I always accept as being correct. Great record and photos, by the way - first on ALA for Australia!
-
-
-
Leuba Ridgway Thank you David. Andrenosoma queenslandi seems to be the accepted name on the Australian Faunal Directory which lists Laphria maura ( on Brisb. insects) as a synonym. I agree Mr Chew does a great job !

Chris Lindorff Name available in database to assign. Also, wondering about the dates of your observations. Is Natureshare picking up the date of the photo from the EXIF file correctly? If you upload the photo/s before entering in the rest of the data and saving, this should work ok. Otherwise, you may have to hit the button to tell it to use the Camera Data Stamp. For this photo, wondered if it could be correct, given the date of the same photo on ALA is a day earlier. Cheers. Chris.
-
-
Martin Lagerwey The error occurs because it was brought back and photographed the next day. I collect them in case dissections become important one day. It was seen on the earlier date but camera data is correct too. I can change that to the observed date if you think that is important.
-
-
Chris Lindorff A day here or there is not important at all. Thanks for the explanation. The same happened for me, when I photographed the beetles today that I collected yesterday. Cheers. Chris.
