Recently I noticed that my harvester ants seem to ignore the poppy seeds I give them. The colony lives in a test tube and has just 20 workers, they don't seem to drag those seeds around or deeper in the test tube. Even though poppy seeds are recommended for them at this stage.
Or they just eat so little that I cannot notice it? And can poppy seeds go rancid after some time?
I still can't give them any larger seeds with hard husks as soon as there's no majors yet.
