This is the 2nd Tarantula Wolf Spider burrow that I discovered a while back (more info) and she was considerably smaller than the first one I found which of course is no longer with us.
However, this morning, I took a look to see how she was doing and noticed that she’s enlarged the burrow and weaved a huge new opening. It didn’t take long for her to come and poke herself out to see what I was doing.
Just for scale, the opening is now around 8cm! Also, the new resident down at the river burrow has closed the entrance, so I suspect she is already having babies!
