I've solved a mystery, part of one anyway. Often I finish a run with my chest and arms covered with dead ants. Vexing, because ants, as you know, live on the ground. I had always explained this conundrum by the brushing up against overhanging branches, because many of the trees here in central Texas are ant infested. Nay, the answer is much simpler. Upon closer inspection, the small dead ones have wings. Beg your pardon, highnesses.
Solenopsis invicta, or the red imported fire ant (RIFA), has undergone two critical mutations recently. Traditional territorial defense communication has broken down, leaving an intensified war raid attitude among all RIFAs, against anybody and anything, including their own. Secondly, one queen per colony, crux of formic hierarchy, has broken down as well, with several queens occupying a single colony. The result is an exponential increase in number and aggression among one of the most numerous and aggressive species in existence. The amount of queens that end up on my post-run chest is testament to the sheer number that patrol the ground. In central Texas, total
invicta numbers have increased 40 fold in the last 25 years, while
all other total arthropod, ant, and other insect numbers have fallen.
Invicta is responsible for more extinctions in the area during recorded history than any other known phenomenon.
