It rained this evening, and I found a Brachymyrmex queen crawling along the wall in my ant room. I found another outside, crawling on the side wall of a plastic bin. I guess they like to climb walls.
Argentine ants were relocating to some dry leaf litter wedged in a tree, and I vacuumed up a few hundred workers and probably about 20 or so queens.
My Pheidole tysoni colony has tons of males that eclosed a week or two ago, and so I would speculate that they would be flying around now, as well.
