It's a very large ant (for my few parameters) with a 10/12 mm. Have a very lethargic behavior (I sometimes thought it was dead) but sometimes she moved a little. He fled from the light and turned away from the wet cotton. In addition to all these details, part of her body is reddish brown with black head and striped abdomen.
