Colobopsis saundersi

Colobopsis saundersi, synonym Camponotus saundersi, is a species of ant found deep in Malaysia, belonging to the genus Colobopsis. At first glance it appears to be an ordinary ant. When either its colony or its own life faces danger far beyond what it can handle on its own a worker can explode suicidally and aggressively as an ultimate act of defense, an ability it has in common with several other species in this genus and a few other insects. The ant has an enormously enlarged mandibular (shotgun) gland, many times the size of a normal ant, which when its trapped in a corner with no escape, produces defense adhesive acidic secretions.
