Cutter Ants (edited for formatting and clarity)

Hello, everyone. While we were gone, the weather in South Texas was mostly cool and damp. The plants loved it! And, to my surprise, so did the ants that have made their home down the road.

This is what we saw while walking. (Bearing in mind that I had thought the ant city had died out last summer.)

 The shoe is left in for scale!

This was really sudden. Presumably the ants were hiding during the day, avoiding the heat, and possibly there was another entrance or two on the other side of the fence. 

These are the kind of ants that children's "ant science kits" come with. They cut leaves from trees, shrubs, and even small plants, carry them back into their underground city, and grow fungus on them. Then they eat the fungus. They're farmers, actually!
