Comment:
this l.niger worker is repelled by the smell of s.fugax. and sometimes also by the powerful sting of this tiny and aggressive ant. the poison gland of s.fugax can spray an alkaloid repellant substance. so often there is no fight at all when s.fugax steals brood for food.

so i was surprised to see a colony of Solenopsis fugax. right near the chambers of lasius niger! -- Solenopsis fugax is a very tiny ant 2mm. 6000 of them have the weight of one gram. one colony can have several 100,000 workers! polygyn. is true kleptobiont or thief ant but can also live on its own, eats aphids.

scouts of S.fugax make many tiny tunnels to search for the brood of the other colony. lasius niger is too large to enter the tunnels.

my first ID attempt with key: solenopsis fugax - the antennae have a clear large club. mandibles have 4 teeth. the only solenopsis in Switzerland.
