Hey all,
Just wondering if anyone has any ideas of why this is happening, good or bad. In the past few days our Acromyrmex versicolor have been putting sand into the section of their chamber where the lid connects (see attached). My wife thinks it is to minimize any draft that might be coming through. It has been getting a little cooler at night as we're getting into fall, perhaps it is related? Anyway, just curious if others have any thoughts on this, thanks!
Jeff
