Colobopsis saundersi

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.

When combat takes a turn for the worse, the worker ant violently contracts its abdominal muscles to rupture its gaster at the intersegmental fold, which also bursts the mandibular glands, thereby spraying a sticky secretion in all directions from the anterior region of its head.

[5][6] The glue, which also has corrosive properties and functions as a chemical irritant, can entangle and immobilize all nearby victims.

[9] The "toxic glue" of C. saundersi is predominately composed of polyacetates, aliphatic hydrocarbons, and alcohols.

However, the chemical is well known to be a urinary metabolite in mammals, with overproduction resulting in toxic acidosis in various species.

Colobopsis saundersi 's two oversized, poison-filled mandibular glands run the entire length of its body from its head to its bulbous gaster at its posterior .
