Interesting that the researcher in that paper has success with dirt in the chamber with the queens. I guess I will have to put some dirt back in with my Pogonomyrmex occidentalis queen.
Just wanted to update on this. My Pogonomyrmex occidentalis queen took full advantage of her test tube with dirt... by promptly digging it all out, creating a mound by the entrance with a gap for her to climb through, and a pile of sound outside the tube. She still likes to rest on the cotton plug in her empty tube.... typical.
She has, however, taken to the chia seeds I bought from the grocery store, at least it appears so. A small crater has appeared in the container, but I have yet to see where she is stashing the missing seeds. The honey water level in her liquid feeder is also steadily dropping.
I know she isn't a Pogonomyrmex californicus queen, but I want to feel included .
