Colony is less than one year old at time of picture. They are bedded one foot from a brick wall in generally shaded mulched over clay/sand.
After a heavy storm these were grounded everywhere in the thousands. Their wings were wet and stuck on surfaces like pavement and cars. If turned over and unstuck their wings could dry, but many died.
App suggests leaf cutter ants, but with wings? And they’re at least an inch long
Biggest freaking ant I’ve ever seen
