I've got the new LIGHTYEAR® Liquid Ant Feeder with Blue 100 (liquid form) in it, in my formicarium with a few hundred Harvester ant workers.
After leaving the ants be for 8 hours and observing them this morning, they've taking small sand granules in the formicarium and dammed up the base of the feeder to cover the holes. In other words, the ants are blocking off the ability to feed from the liquid feeder.
Has anyone observed this? When there was sugar-water in there, they didn't do this to the feeder. Is this their way of trying to "store" the source of food? Any ideas?
I'll take a pic. when I'm back home after work today.
