About the Bullet Ant

Paraponera clavata, commonly known as the bullet ant, is a species of ant known for its extremely painful sting. It inhabits humid lowland rainforests in Central and South America. The specific epithet of the ant, clavata, means "club-shaped". The generic name, Paraponera, translates to "near-Ponera". Because of its fearsome reputation, the ant has several Native American, Spanish, and Portuguese local names in different geographical areas; perhaps the best-known of these is the Venezuelan nickname hormiga veinticuatro (the "24 ant" or "24-hour ant"), referring to the full day of pain that follows being stung; it can also refer to the time it takes to kill a human. In Brazil, the Portuguese names given by locals include formiga cabo verde, formigão, or formigão-preto (big black ant); Native American–derived names include tocandira, and tocanquibira, from the Tupi–Guarani tuca-ndy, which translates to "the one wounding deeply". Other names by which it is called include chacha, cumanagata, munuri, siámña, and yolosa. In Costa Rica, P. clavata is known as bala, meaning "bullet". P. clavata also has several common names in English; it is most commonly known as the bullet... Wikipedia →
