Hi Michael & jgiacon, you may be right that it is Myrmecia forficata, but that species can be pretty similar looking to Myrmecia pyriformis (which I suspect that it is, but can't be sure) so I'm cautiously leaving it a genus level. Cheers, Jon
Hi John, the gold standard for trying to ID an ant from images is to have a picture of the head face-on, (flat on to the camera, neither tilted forward nor backwards), plus an image taken of the dorsal surface (from straight above the ant) and an image taken directly from the side. It is not easy to get these photos in field conditions, with a moving ant, but images taken from a few angles are generally helpful. The other thing is just image clarity, so the fine detail of the ant can be seen - also not always easy to do in the field. Good luck! Jon
