Trivia
In real life, black ants can shoot formic acid. The developers don't implement this in the game because black ants are meant to get you used to basic game mechanics.
Black garden ants (Lasius niger) were replaced with black silky ants because the latter are hosts of the chosen slave-maker ants. They were removed from the game completely from version 0.05 onward.
