In the case of fire ants, the venom consists mainly of alkaloid (>95%) and protein (<1%) components. [2] Stinging ants cause a cutaneous condition that is different from that caused by biting venomous ants.

[71] After getting stung, the immediate response consists of erythema and swelling.
Both the immense pain and the duration of the sting are due to the effects of poneratoxin. [5] In addition to the notorious pain, symptoms of stings from bullet ants (as well as stings from other ants of the genus Paraponera as well as the genus Dinoponera) include fever, cold sweats, nausea, vomiting, lymphadenopathy and cardiac arrhythmias.

Velvet ants avoid predation using the following defense mechanisms: a venomous sting (if female), aposematic coloration, a stridulatory organ in their abdomen, an alarm secretion from their mandibular gland, and a durable exoskeleton. This array of defenses has contributed to the velvet ants being attributed the title of "the indestructible ...
