Yay. Got my colony of these big girls. Their nest in the wild was over a meter deep and about the same wide. They seem to have few chambers linked by long winding tunnels. Makes for a hard digging process. These rank number one in size but number 3 in agression out of all my myrmecia species, with the tarsata being a 2 2 and nigrocincta being 3 1. Apparently they have a more painful sting than the others too (thanks lance).
After a housing shortage I have decided to give these the outworld that is attached to my very large block and just give the block a temporary outworld. I will not bother making it too pretty as I have learned that they will just mess it up. I am not 100% positive that the queen is present but there seems to be one with wing stumps in the right place and we exhausted all of the possible hiding places in the ground. Time will tell.
As much as I like this species for their size, I highly doubt I will be collecting another colony. If I happen to see them flying ill grab a bunch for sure, but the time and energy needed to excavate them is just not worth it.
