Pseudoneoponera sp.
When threatened, some species of Pseudoneoponera create a defensive foam from their venom gland. The foam is produced quickly and in impressive quantities, sometimes forming long chains of single bubbles. Here, I provoked the behavior by picking up a worker with forceps.

The quantity of defensive foam produced by a single Pseudoneoponera ant is surprisingly large. Koh Kong Province, Cambodia (laboratory colony at the University of Illinois)
When I pick up a Pseudoneoponera worker with forceps she emits a defensive stream of foam from her venom gland. (Also, it turns out she stings, too!) Koh Kong Province, Cambodia (laboratory colony at the University of Illinois)
