Of all extant ant species, about 71% are considered to be stinging species, as some subfamilies have evolutionarily lost the ability to sting. [1] Notable examples include a few species of medical importance, such as Solenopsis (fire ants), Pachycondyla , Myrmecia (bulldog ants), and Paraponera (bullet ants).
The toxicity of the venom of the Maricopa harvester ant is well known. Its LD 50 value is 0.12 mg/kg (injected intravenously in mice); 12 stings can kill a 2-kg rat. In comparison, the LD 50 of the honey bee is 2.8 mg/kg—less than one-twentieth as strong. In humans, a Pogonomyrmex sting produces intense pain that can last up to four hours. [3 ...
Red bulldog ant. Bulldog ants, from the genus Myrmecia, are native to Australia, with all but one of the ninety or so species found on the continent. Belonging to the ant subfamily Myrmeciinae, they are among the most primitive extant ants in the world. This species is known to cause some fatalities in sensitive humans. [11] Bullet ant
[1] [2] They are often distinguished from poisonous animals, which instead passively deliver their toxins (called poison) to their victims upon contact such as through inhalation, absorption through the skin, or after being ingested. [1] [2] [3] The only difference between venomous animals and poisonous animals is how they deliver the toxins. [3]
The stings of the red imported fire ant in animals are painful, and may prove life-threatening. [70] In dogs, stings from the red imported fire ant can cause pustular dermatosis, a condition where pustules appear in crops as a result of the ant sting. [71] After getting stung, the immediate response consists of erythema and swelling.
Colobopsis saundersi (synonym Camponotus saundersi), also called the Malaysian exploding ant or suicide ant, is a species of ant found in Malaysia and Brunei, belonging to the genus Colobopsis. 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 ...
An ant pictured in the coat of arms of Multia, a town in Finland. Ant society has always fascinated humans and has been written about both humorously and seriously. Mark Twain wrote about ants in his 1880 book A Tramp Abroad. [233] Some modern authors have used the example of the ants to comment on the relationship between society and the ...
The original pissant is any of a certain group of large ant species, commonly called wood ants, that make mounded nests in forests throughout most of Europe. [2] The name pissant arises from the urine -like odour produced by their nesting material—needles and straw from pine trees—and the formic acid that constitutes their venom . [ 3 ]
