Pheidole dentata
-----------------------
Well, they STILL refuse to stop production, and as a result, they've just about outgrown their Mini Hearth. I've had to add a test tube to the side connection port for them to store their hundreds of extra brood! Currently there's been an average of about 150 workers with the brood pile in the tube at all times, with about 10 majors accompanying them. They've been eating a large superworm every 2 days or so, and downing an entire liquid feeder full of sugar water each week. I've got some pictures that turned out decent, too.
I'm working on getting decent pics of my other ants that aren't in hibernation, so watch out for the next update here in a bit.
Also, try to count how many majors/major pupae are in those pics!
