Stenamma debile - <p>A common but discrete ant species living in forest/woodland leaf litter. It has a pecular thanatosis behavior : when disturbed it mimics death by stopping any movements and taking strange positions with its legs. Progressively, it beggins to move again but with very jerky movements, limping as if it were wounded. Finaly it moves again normally. You can imagine this behavior from the series of 3 pictures here. I suppose that his name "debile" comes from that behavior. </p> <p><a rel="nofollow" class="external autonumber" href="https://www.flickr.com/photos/sanmartin/8732307193/">[1]</a> </p> © Gilles San Martin from Namur, Belgium - CC BY-SA 2.0 - Wikimedia Commons
