kamikazi ants

Woe is the insect that crosses the path of the Colobopsis explodens ant.
Scientists exploring the Borneo jungle have just discovered the species, which dwells in the trees, and they were most intrigued by the ant’s unique ability – to explode and shower toxic yellow goo on to its enemies....This suicidal tendency, which is similar to that of a bee delivering a sting when threatened, is called autothysis, and is common in superorganisms like ants, who work as a collective and where the needs of the group are more important than the individual in a colony.
